【问题描述】：

1) 我无法与数组相交： 2）我无法使用键获取关联 POST 数组的值

$adbcols=Array ( [tcid] => tcid .... array containing database column names

$aformval=Array ( ['tcbcheck'] => on ['tcprice'] => 100 ['tctitf'] => 01 

.. 包含 POST 数据的数组

function amatchfnc($a, $b) 
    if ($a==$b)  return 0; 
    return ($a>$b) ? 1:-1; 
     // function amatchfnc($a, $b)

foreach ($_POST as $apie=>$aformval  ) 

       $aresf=array_intersect_ukey($aformval,$adbcols,"amatchfnc");
 

更多完整代码：

foreach ($_POST as $apie=>$aformval  ) 
echo "<br><br> apie:"; print_r($apie);  
echo "<br><br> aformval:";  print_r($aformval);  //prints, also  aformval[tcbcheck]
echo "<br><br> aformval[tcbcheck]".$aformval['tcbcheck']; //gives empy line     

if(isset($_SESSION['vcurprcode']))  $aformval['tcfkcode']=$_SESSION['vcurprcode']; 
                               $aresf=array_intersect_ukey($aformval,$adbcols,"amatchfnc");

echo "<br><br><br> print_r(aresf)="; print_r($aresf);
                                            insertvalues($aresf,$adbcols, $conn, $vdbname, $tprice);
 //foreach ($_POST as $apie ) 

来自 prin_r 的输出，回显：

$aresf 应该包含所有 $aformal 值。 我进行交集只是为了检查 aref 的列名是否与数据库的列名一致。 $adbcols 我是从数据库模式中获取的。

我发布的 html 文件包含以下段落：

<input type= "text" name="mon01['tcprice']"  value="<?php echo $mon01['tcprice']; ?>"  " > 

<input type="range" name="mon01[range]" min="0" max="1000" >

<input type="hidden" class="mon" name="mon01['tctitf']"  value="01"; " size="1" >

<input type="hidden" class="mon" name="mon01['tcdatefromto']"  
value="priceFrom20140101To20140131"; " size="1" >

<input type="hidden" class="mon" name="mon01['tcbset']"  value="3"; " size="1" >

<input type="hidden" class="mon" name="mon01['tcbsettit']"  value="month"; " >

<textarea  cols="50" rows="3" name="mon01['tcdesc']" 
value="<?php echo $mon01['tcdesc'];  ?>" > </textarea>

通常数组交集有效。下面的例子是一些数组：

<?php
$af=array( "a"=>"a","c"=>"c", "e"=>"e" );
$ad=array( "a"=>"a","b"=>"b","c"=>"c","d"=>"d", "e"=>"e" );

$af=array_intersect_ukey($af,$ad,"amatchfnc");
    echo "<br> print_r(af)="; print_r($aresf);
?>

给出：print_r(aresf)=Array ([a] => a [c] => c [e] => e)

但如果我尝试与 POST 数组 $aformval 相交，我会得到奇怪的结果。如何与 POST 数组相交？

【参考方案1】：

使用array_merge http://in1.php.net/array_merge

$result = array_merge($array1, $array2);

【参考方案2】：

我不完全确定您的要求，但我认为这是您想要的。你可以试试array_merge()。将一个或多个数组的元素合并在一起，以便将一个数组的值附加到前一个数组的末尾。由于您 have same key 在两个数组中，第二个数组的键 => 值将在结果数组中（在本例中为 $aformval）

$adbcols = array('tcid'=>'tcid','tcbcheck'=>'tcbcheck');
$aformval = array('tcprice'=>'100','tcbcheck'=>'on','tctitf'=>0,'tcid'=>1);
$arr = array_merge($adbcols,$aformval);
print_r($arr);

结果：

Array
(
    [tcid] => 1
    [tcbcheck] => on
    [tcprice] => 100
    [tctitf] => 0
)

如果您需要检查$aformaval keys 是否存在于$adbcols 中，请尝试

$arr =array_diff(array_keys($aformval),array_keys($adbcols));

如果count($arr) > 0，那么您在$aformval 中拥有$adbcols 中不存在的键。可以通过 print_r($arr); 看到区别

【讨论】：

我不需要附加值。我只想检查 $aformal 键是否对应于数据库列名。 $adbcols 包含数据库列名作为键和值:) 我从 mysql 数据库模式中获取它。

交集不适用于 POST 数组。如果我手动编写数组，它会起作用。也许有一些技巧必须如何处理帖子？

请阅读上面的答案。原因是我将 $aformval["'key'"] 与 $dbcols["key"] 相交。解决办法是改html表单。

【参考方案3】：

原因是我将$aformval["'key'"] 与$dbcols["key"] 相交

或者我必须制作不带引号的 html 表单：

<input type= "text" name="mon01[tcprice]" value="<?php echo $mon01[tcprice]; ?>"   > 

或者我必须向 adbcols 键添加 quates，即使用 $adbcols["'tcprice'"]。

 <input type= "text" name="mon01['tcprice']" value="<?php echo $mon01['tcprice']; ?>"   >
