Question

当我使用cURL获取网站并对结果执行strlen（）时，我得到72354.但是当我通过htmlspecialchars（）传递结果然后执行strlen（）时，我得到0.任何想法？这是我的代码：

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/search?q=test');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);

$result = curl_exec($ch);
echo strlen($result);
echo '<br>';
echo strlen(htmlspecialchars($result));

Answer 1

试

<?php

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.google.com/search?q=test');
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);

$result = curl_exec($ch);
echo strlen($result);
echo '<br>';
echo strlen(htmlspecialchars($result, ENT_QUOTES));
echo '<br>';
echo htmlspecialchars($result, ENT_COMPAT,'ISO-8859-1', true);

?>

htmlspecialchars不能处理字符串
