没有结束分隔符'/'发现错误 [英] No ending delimiter '/' found error

问题描述

我调整了一个小脚本来检查反向链接。然而，我继续收到错误

I have adjusted a small script to check backlinks. Yet I keep on getting the error

警告：preg_match（）[function.preg-match]：在第17行找不到结束分隔符'/'。

Warning: preg_match() [function.preg-match]: No ending delimiter '/' found in line 17.

<?php
function file_get_contents_curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
$data = curl_exec($ch);
curl_close($ch);

return $data;
}

function google_backlink($uri)
{
$url = 'http://www.google.com/search?q=link:facebook.com&hl=en&filter=0';
$v = file_get_contents_curl($url);
preg_match('/<div id="resultStats">About \(.*?)\ ',$v,$s);
$s_number = explode(".", $s[1]);
$i = 0;
if ($s[1]!=0) {
    return $s[1];
} else {
    return ($r[1]) ? $r[1] : '0';
}
}

echo "Google backlink = ".google_backlink($url)."<br />";   
?>

有什么问题 preg_match（'/< div id =resultStats>关于\（。*？）\'，$ v，$ s）;

推荐答案

错误非常清楚，你没有包括尾随的 / ：

The error is very clear really, you didn't include the trailing /:

preg_match('/<div id="resultStats">About \(.*?)\ /',$v,$s);

老实说，我怀疑你的逃脱角色是否合适。也许你的意思是 \）？

I honestly doubt your escape characters are well placed though. Maybe you meant \)?
