Question

在下面的代码中，我如何检查$variable是否等于“$ one”。

<?php  
    $one = array (1,2,3);
    $two = array (4,5,6);

    $variables = array ($one, $two);

    foreach ($variables as $variable){
        //check if the $variable is equal to "$one"
            //do stuff that is specific for array $one
    }   
?>

Answer 1

有关详细信息，请访问this

<?php  
    $one = array (1,2,3);
    $two = array (4,5,6);

    $variables = array ($one, $two);

    foreach ($variables as $variable){
        //check if the $variable is equal to "$one"
           if($variable === $one)
            //do stuff
    }   
?>

Answer 2

简单地说，你不能。您可以在值中添加键：

<?php  
$one = array (1,2,3);
$two = array (4,5,6);

$variables = array ( 'one' => $one, 'two' => $two);

foreach ($variables as $key => $variable){
    //check if the $variable is equal to "$one"
    if( $key === 'one' ) {
        //do stuff that is specific for array $one
    }
}

Answer 3

  foreach ($variables as $variable){
        if($variable == $one)//TRUE if $a and $b have the same key/value pairs.
        {

        }
    }

如果您想检查订单和类型，您可以按照以下步骤进行操作：

  foreach ($variables as $variable){
        if($variable === $one)
        {

        }
    }

Answer 4

您可以查看

if($variable===$one)

你正在拍摄多维数组。请记住，您需要检查“===”，而不是“==”，因为它不是变量甚至是字符串。
