php - 如何在数组变量中使用 Stristr

Question

我需要检查数组变量中的单词，我需要这样的东西:

$banned = array('word1','word2','word3','word4');


if (stristr($title, $banned) !== false) {

    //$title contains a banned word 

}else{

    //$title not contains any word of $banned variable array

}

Answer 1

<?php
$banned = array('word1','word2','word3','word4');

$hit = false;
foreach ($banned as $banned_item)
{
    if (strpos($title, $banned_item) !== false)
    {
        $hit = true;
        break;
    }
}

if ($hit)
{
    // $title contains a banned word
}
else
{
    //$title not contains any word of $banned variable array
}

上面的代码是区分大小写的，如果你想让你的代码不区分大小写，只需更改:

  if (strpos($title, $banned_item) !== false)

到:

  if (stristr($title, $banned_item) !== false)
