Question

我想从链接源代码中获取哈希并将其存储在变量中源代码是：

Profile.init({"user_id":37462,"loc":null,"back":"Leeter Leeter","last_names":[],"max_name_len":280,"hash_hash":"8cc8f7b2dcb4331676"});

我想要的哈希是：8cc8f7b2dcb4331676

我试过这段代码，但它没有用。

<?php
$data = file_get_contents("Link");
if (preg_match("/hash_hash":"([a-zA-Z0-9]+)"/i", $data, $matches))
     print "The hash is: $matches[1]";
else
     print "The page doesn't have a hash";

您可以在preg_match_all（）中使用以下模式：

'/"hash_hash":"([^"]+)"/i'

示例：

$x='Profile.init({"user_id":37462,"loc":null,"back":"Leeter Leeter","last_names":[],"max_name_len":280,"hash_hash":"8cc8f7b2dcb4331676"})';
preg_match_all('/"hash_hash":"([^"]+)"/i',$x,$matches);
print_r($matches[1]);
