如何用给定的数字替换模式中的x？

Posted 2021-03-27

我还试过了......

 <?

$dataArry = array (
"aab"=> array(
    "mobile"=>'123456789',
    "country"=>"Antigua and Barbuda",
    "countryCode"=>"+1-268",
    "pattern"=>"3#4",
    "pattern2"=>"(xx)-xxxxxxx"
)
);

$data = $dataArry["aab"]["mobile"];    //  number with leading 0...

if ($data[0] == "0" ) {  //remove the leading 0 from number...
    $data = substr($data, 1); 
}

$pattern = $dataArry["aab"]["pattern2"];
echo preg_replace("([x]+)", $data, $pattern);

?>

我得到了(123456789)-123456789的结果，但我希望结果像(12)-3456789

实际上，我想根据该国家/地区转换所有数字格式的手机号码，因此，我在数据库中保存了一个国家/地区的模式。所以，我可以在以后需要显示时转换它们...

以前我使用的是这个代码，但它不是更动态，因为格式可以像(12) 44 33 222, or 12 44 33 22。所以我想保存像（xx）x​​x xx xxx，xx xx xx xx这样的模式，并用数字替换所有x。对于模式中的x，x的数量始终相同。

<?
$match = "";

$dataArry = array(
    "ind" => array(
        "mobile" => '07505942189',
        "country" => "india",
        "countryCode" => "+91",
        "pattern" => "3#3#4"
    ),
    "us" => array(
        "mobile" => '3784001234',
        "country" => "US",
        "countryCode" => "+1",
        "pattern" => "3#3#4"
    ),
    "aab" => array(
        "mobile" => '4641234',
        "country" => "Antigua and Barbuda",
        "countryCode" => "+1-268",
        "pattern" => "3#4"
    ),
    "afg" => array(
        "mobile" => '0201234567',
        "country" => "Afghanistan",
        "countryCode" => "+93",
        "pattern" => "2#7"
    )
);
$result .= $dataArry["afg"]["countryCode"] . " ";
$data = $dataArry["afg"]["mobile"]; // indian number with leading 0...
if ($data[0] == "0") { //remove the leading 0 from number...
    $data = substr($data, 1);
}


$string = $dataArry["afg"]["pattern"]; // pattern code 

$string = explode("#", $string); //making array of string pattern code.

foreach ($string as $vals) {
    $match .= "(d{" . $vals . "})";
}

//if(  preg_match( '/^+d(d{3})(d{3})(d{4})$/', $data,  $matches ) )
if (preg_match("/" . $match . "/", $data, $matches)) {
    for ($i = 1; $i < count($matches); $i++) {
        if ($i == 1) {
            $result .= "(";
        }
        $result .= $matches[$i];
        if ($i == 1) {
            $result .= ")";
        }

        if ($i < count($matches) - 1) {
            $result .= "-";
        }



    }
    echo $result;
}

答案

你可以使用preg_replace_callback来完成它：

$mobile = '123456789';
$pattern = '(xx)-xxxxxxx';

echo preg_replace_callback('/x+/', function ($match) use (&$mobile) {
    $length = strlen($match[0]);

    $replacement = substr($mobile, 0, $length);

    $mobile = substr($mobile, $length);

    return $replacement;
}, $pattern);
