php 设置字符编码为utf-8

header("Content-Type: text/html;charset=utf-8");


路径格式化(替换双斜线为单斜线)

function path_formate($str){
    return str_replace(\'\\\\\\\\\',\'\\\\\',$str);
}

转码

function gbk($str){return iconv(\'utf-8\',\'gbk\',$str);}
function utf8($str){return iconv(\'gbk\',\'utf-8\',$str);}
---

打印输出

function dump($var)
{
    echo \'<pre>\';
    print_r($var);
    echo \'</pre>\';
}

function vp($var)
{
    echo \'<pre>\';
    var_dump($var);
    echo \'</pre>\';
}

function dd($var)
{
    echo \'<pre>\';
    var_dump($var);
    echo \'</pre>\';
    die;
}

api返回信息

/**
*  数据返回
 * @param  [int] $code [结果码 200:正常/4**数据问题/5**服务器问题]
 * @param  [string] $msg  [返回的提示信息]
 * @param  [array]  $data [返回的数据]
 * @return [string]       [最终的json数据]
*/
public function return_msg($code, $msg = \'\', $data = []) {
 
    /*********** 组合数据  ***********/
    $return_data[\'code\'] = $code;
    $return_data[\'msg\']  = $msg;
    $return_data[\'data\'] = $data;
 
    /*********** 返回信息并终止脚本  ***********/
    echo json_encode($return_data,JSON_UNESCAPED_UNICODE);
    die;
}

字符串截取

方法一:

在公共的common.php中

//字符串截取并且超出显示省略号
function subtext($text, $length)
{
if(mb_strlen($text, ‘utf8’) > $length)
return mb_substr($text,0,$length,’utf8′).’ …’;
return $text;
}

在模版中调用则:
{$tops.title | subtext=18}

方法二:

在公共的common.php中

//字符串截取

function cut_str($sourcestr,$cutlength)  

{  

   $returnstr=\'\';  

   $i=0;  

   $n=0;  

   $str_length=strlen($sourcestr);//字符串的字节数  

   while (($n<$cutlength) and ($i<=$str_length))  

   {  

      $temp_str=substr($sourcestr,$i,1);  

      $ascnum=Ord($temp_str);//得到字符串中第$i位字符的ascii码  

      if ($ascnum>=224)    //如果ASCII位高与224,  

      {  

$returnstr=$returnstr.substr($sourcestr,$i,3); //根据UTF-8编码规范,将3个连续的字符计为单个字符          

         $i=$i+3;            //实际Byte计为3  

         $n++;            //字串长度计1  

      }  

      elseif ($ascnum>=192) //如果ASCII位高与192,  

      {  

         $returnstr=$returnstr.substr($sourcestr,$i,2); //根据UTF-8编码规范,将2个连续的字符计为单个字符  

         $i=$i+2;            //实际Byte计为2  

         $n++;            //字串长度计1  

      }  

      elseif ($ascnum>=65 && $ascnum<=90) //如果是大写字母,  

      {  

         $returnstr=$returnstr.substr($sourcestr,$i,1);  

         $i=$i+1;            //实际的Byte数仍计1个  

         $n++;            //但考虑整体美观,大写字母计成一个高位字符  

      }  

      else                //其他情况下,包括小写字母和半角标点符号,  

      {  

         $returnstr=$returnstr.substr($sourcestr,$i,1);  

         $i=$i+1;            //实际的Byte数计1个  

         $n=$n+0.5;        //小写字母和半角标点等与半个高位字符宽...  

      }  

   }  

         if ($str_length>$i){  

          $returnstr = $returnstr . "...";//超过长度时在尾处加上省略号  

      }  

    return $returnstr;  

} 

在模版中调用则:
{$brand.brand_description|cut_str=###,10}


数组 字符串 对象 json格式的字符串互转

/**
 * 对象 转 数组
 *
 * @param object $obj 对象
 * @return array
 */
function object2array(&$object) {
    $object =  json_decode( json_encode( $object),true);
    return  $object;
}


/****对象转json数组格式的字符串*****/
function obj2arr($object) {
    
    $json_object = json_encode($object);
    echo "<pre>";
    var_dump($json_object);die;
    $arr = json_decode($json_object, 1);
    return $arr;
}

/**
 * 数组 转 对象
 *
 * @param array $arr 数组
 * @return object
 */
function array_to_object($arr) {
    if (gettype($arr) != \'array\') {
        return;
    }
    foreach ($arr as $k => $v) {
        if (gettype($v) == \'array\' || getType($v) == \'object\') {
            $arr[$k] = (object)array_to_object($v);
        }
    }
 
    return (object)$arr;
}


$arr = array(
    \'name\'=>\'haima\',
    \'age\'=>32,
    \'gender\'=>\'nan\'
);
$a=(Object)($arr); //数组转对象
echo \'<pre>\';
var_dump($a);

$jsonstring=json_encode($array,JSON_UNESCAPED_UNICODE); //对象转json字符串 不转义中文汉字
echo \'<pre>\';
var_dump($jsonstring);

$abj=json_decode($array); //json转对象
$array=json_decode($array,true); //json转数组


echo \'<pre>\';
$b=(Array)($a); //对象转数组
var_dump($b);

强制类型转换

/**
 * 强制类型转换
 * @param string $data
 * @param string $type
 * @return mixed
 */
private function typeCast(&$data, $type)
{
    switch (strtolower($type)) {
        // 数组
        case \'a\':
            $data = (array) $data;
            break;
        // 数字
        case \'d\':
            $data = (int) $data;
            break;
        // 浮点
        case \'f\':
            $data = (float) $data;
            break;
        // 布尔
        case \'b\':
            $data = (boolean) $data;
            break;
        // 字符串
        case \'s\':
        default:
            if (is_scalar($data)) {
                $data = (string) $data;
            } else {
                throw new \\InvalidArgumentException(\'variable type error:\' . gettype($data));
            }
    }
}

 

 


php序列化serialize与返回序列化unserialeze

serialize() 把变量和它们的值编码成文本
unserialize() 恢复原先变量


创建日志文件

  1. 方法一(适合临时用):
//数组/字符串都可以
file_put_contents( \'log.log\', date(\'Y-m-d H:i:s\',time()) .\' \' . var_export($_REQUEST,true) . "\\r\\n", FILE_APPEND);
  1. 方法二:

例: /www.wdmcake.com/data/log/日期/$file文件名

/**
*$str array/str 要写入的内容
*$dir str 日期文件夹里面的新建的文件夹名字  例如 /www.wdmcake.com/data/log/201806/sms_apiaas
*$file string 文件的名字 例:send_log_20180628.log
*/
function wdmlog($str,$dir=\'log\',$file=\'log\')
{
    if (!file_exists(ROOT_PATH . \'data/log/\' . date(\'Ym\'). \'/\' . $dir))
    {
        make_dir(ROOT_PATH . \'data/log/\' . date(\'Ym\'). \'/\' . $dir);
    }
    $str = is_array($str) ? var_export($str,true):$str;
       file_put_contents(ROOT_PATH . \'data/log/\' . date(\'Ym\'). \'/\' . $dir.\'/\' . $file .\'_\' . date(\'Ymd\') . \'.log\', local_date(\'Y-m-d H:i:s\') .\' \' . $str . "\\r\\n", FILE_APPEND);
}    
  1. 方法三:
function create_log($data,$merchant,$agency,$file=\'\')
{
   if(empty($merchant)) die("商户code不可为空");
   if(empty($agency)) die("平台code不可为空");
   $file_path = ROOT_PATH . \'logdata/\'.$merchant.\'/\'.$agency;
   if(!is_dir($file_path)){
        mkdir($file_path, 0777, true); 
    }    
    file_put_contents($file_path.\'/\'.$agency.\'_\' . $file . date(\'Ymd\',time()) . \'.log\', date(\'Y-m-d H:i:s\',time()) .\' \' . var_export($data,true) . "\\r\\n", FILE_APPEND);
}

获取ip地址

  1. 方法一
$_SERVER[\'REMOTE_ADDR\']
  1. 方法二
    /** 
     * 获得访问的IP 
     * Enter description here ... 
     */  
    function getIP() {  
        return isset($_SERVER["HTTP_X_FORWARDED_FOR"])?$_SERVER["HTTP_X_FORWARDED_FOR"]  
        :(isset($_SERVER["HTTP_CLIENT_IP"])?$_SERVER["HTTP_CLIENT_IP"]  
        :$_SERVER["REMOTE_ADDR"]);  
    } 
  1. 方法三
/**
 * 获得用户的真实IP地址
 *
 * @access  public
 * @return  string
 */
function real_ip()
{
    static $realip = NULL;

    if ($realip !== NULL)
    {
        return $realip;
    }

    if (isset($_SERVER))
    {
        if (isset($_SERVER[\'HTTP_X_FORWARDED_FOR\']))
        {
            $arr = explode(\',\', $_SERVER[\'HTTP_X_FORWARDED_FOR\']);

            /* 取X-Forwarded-For中第一个非unknown的有效IP字符串 */
            foreach ($arr AS $ip)
            {
                $ip = trim($ip);

                if ($ip != \'unknown\')
                {
                    $realip = $ip;

                    break;

            }
        }
        elseif (isset($_SERVER[\'HTTP_CLIENT_IP\']))
        {
            $realip = $_SERVER[\'HTTP_CLIENT_IP\'];
        }
        else
        {
            if (isset($_SERVER[\'REMOTE_ADDR\']))
            {
                $realip = $_SERVER[\'REMOTE_ADDR\'];
            }
            else
            {
                $realip = \'0.0.0.0\';
            }
        }
    }
    else
    {
        if (getenv(\'HTTP_X_FORWARDED_FOR\'))
        {
            $realip = getenv(\'HTTP_X_FORWARDED_FOR\');
        }
        elseif (getenv(\'HTTP_CLIENT_IP\'))

        else
        {
            $realip = getenv(\'REMOTE_ADDR\');
        }
    }

    preg_match("/[\\d\\.]{7,15}/", $realip, $onlineip);
    $realip = !empty($onlineip[0]) ? $onlineip[0] : \'0.0.0.0\';

    return $realip;
}

PHP限制IP访问 只允许指定IP访问 允许*号通配符过滤IP

/** 
 * 检测访问的ip是否为规定的允许的ip 
 * Enter description here ... 
 */  
function check_ip(){  
    $ALLOWED_IP=array(\'192.168.2.*\',\'127.0.0.1\',\'192.168.2.49\');  
    $IP=getIP();  
    $check_ip_arr= explode(\'.\',$IP);//要检测的ip拆分成数组  
    #限制IP  
    if(!in_array($IP,$ALLOWED_IP)) {  
        foreach ($ALLOWED_IP as $val){  
            if(strpos($val,\'*\')!==false){//发现有*号替代符  
                 $arr=array();//  
                 $arr=explode(\'.\', $val);  
                 $bl=true;//用于记录循环检测中是否有匹配成功的  
                 for($i=0;$i<4;$i++){  
                    if($arr[$i]!=\'*\'){//不等于*  就要进来检测,如果为*符号替代符就不检查  
                        if($arr[$i]!=$check_ip_arr[$i]){  
                            $bl=false;  
                            break;//终止检查本个ip 继续检查下一个ip  
                        }  
                    }  
                 }//end for   
                 if($bl){//如果是true则找到有一个匹配成功的就返回  
                    return;  
                    die;  
                 }  
            }  
        }//end foreach  
        header(\'HTTP/1.1 403 Forbidden\');  
        echo "Access forbidden";  
        die;  
    }  
}  

获取地址路径里0到第一个\\线的部分

function f_dirname($f_path){
    return substr($f_path,0,strrpos($f_path,\'\\\\\'));
}

获取当前文件所在的文件路径

define(\'CUR_API_PATH\', rtrim(str_replace(\'\\\\\', \'/\', dirname(__FILE__)),\'/\').\'/\');

获取随机字符串

/**
 * 随机字符
 * @param int $length 长度
 * @param string $type 类型
 * @param int $convert 转换大小写 1大写 0小写
 * @return string
 */
function random($length=10, $type=\'letter\', $convert=0)
{
    $config = array(
        \'number\'=>\'1234567890\',
        \'letter\'=>\'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ\',
        \'string\'=>\'abcdefghjkmnpqrstuvwxyzABCDEFGHJKMNPQRSTUVWXYZ23456789\',
        \'all\'=>\'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890\'
    );

    if(!isset($config[$type])) $type = \'letter\';
    $string = $config[$type];

    $code = \'\';
    $strlen = strlen($string) -1;
    for($i = 0; $i < $length; $i++){
        $code .= $string{mt_rand(0, $strlen)};
    }
    if(!empty($convert)){
        $code = ($convert > 0)? strtoupper($code) : strtolower($code);
    }
    return $code;
}

中文字符串反转


检查目标文件夹是否存在,如果不存在则自动创建该目录

/**

默认获得文件修改时间

function filetime($way,$char=\'m\'){
    date_default_timezone_set(\'PRC\');
    switch($char){
        case \'c\':$localtime = date(\'Y-m-d H:i:s\',filectime($way));

        break;
    }
    return $localtime;
}

判断后缀类型

function suffixtype($f_path){
    $info = pathinfo($f_path);
    $f_type = \'file\';
    switch(strtolower(@$info["extension"])){
        case \'jpg\':case \'jpeg\':case \'gif\':
