php - 检查字符串是否包含数组的任何值？

Question

$search=array("<",">","!=","<=",">=")
$value="name >= vivek ";

我想检查 $value 是否包含 $search 数组的任何值。我可以找到使用 foreach 和 strpos 函数。不求助于foreach，我还能找到答案吗？如果是这样，请帮助我解决这个问题。

将$value分解成数组，然后使用php中的array_intersect()函数检查字符串是否不包含数组的值。使用下面的代码

    <?php
    $search=array("<",">","!=","<=",">=");
    $value='name >= vivek ';
    $array = explode(" ",$value);

    $p = array_intersect($search,$array);
    $errors = array_filter($p);
//Check if the string is not empty
    if(!empty($errors)){
    echo "The string contains an value of array";
    }
    else
    {
    echo "The string does not containe the value of an array";
    }

    ?>
