求问一个正则表达式的问题
想匹配一个网页地址中的所有图像地址，写了正则表达式如下：

$reg="/<img \s*.*src\s*=\s*[\"|\']?\s*([^ alt=" 求问一个正则表达式的有关问题 " >\"\']*)/i";

Copy after login

为什么像如下的图像文件地址：

<img  src="../Images/Album Cover/album_012.jpg" alt=" 求问一个正则表达式的有关问题 " >

Copy after login

只能匹配到：



到空格的时候就终止了？

（[^>\"\']*）这个条件应该不包含空格啊？

$s = '<img  src="../Images/Album Cover/album_012.jpg" alt=" 求问一个正则表达式的有关问题 " >';

preg_match_all($reg, $s, $m);

print_r($m);
