尝试在任何网站内查找内容。如果内容存在,则需要做其他事情。
Xpath | PHP
<?php
//Load the HTML page
$html = file_get_contents('http://www.example.com/');
//Parse it. Here we use loadHTML as a static method
//to parse the HTML and create the DOM object in one go.
@$dom = DOMDocument::loadHTML($html);
//Init the XPath object
$xpath = new DOMXpath($dom);
$vals = $xpath->query( '//script[not[contains(text(), "sample")]]' );
if (($vals) > 0) {
echo 'finding text, not in the website';
} else {
echo "Test";
}
?>
我无法探讨如何执行此条件。

您可以使用count()
if ((count($vals)) > 0) {
echo 'finding text, not in the website';
} else {
echo "Test";
}
