我想获取字符串值，然后使用urldecode()。
Javascript
document.write(unescape('%46%43%20%42%72%61%73%6f%76%20%76%73%2e%20%43%53%4d%53%20%49%61%73%69'));
PHP
$string = "document.write(unescape('%46%43%20%42%72%61%73%6f%76%20%76%73%2e%20%43%53%4d%53%20%49%61%73%69'));";
preg_match('/document.write(unescape(\'.*\'));/', $string,$matches);
var_dump($matches);
但是这返回array(0) { }
最佳答案
你可以试试
$string = "document.write(unescape('%46%43%20%42%72%61%73%6f%76%20%76%73%2e%20%43%53%4d%53%20%49%61%73%69'));";
preg_match('/document.write\(unescape\(\'(.*)\'\)\);/', $string,$matches);
var_dump($matches[1]);
输出
string '%46%43%20%42%72%61%73%6f%76%20%76%73%2e%20%43%53%4d%53%20%49%61%73%69' (length=69)
