婚配字符串

匹配字符串

$handle="http://ec2.images-amazon.com/images/I/311%2Bk07cuIL._SL500_AA280_.jpg,http://ec2.images-amazon.com/images/I/418Qdk6bctL._SL500_AA280_.jpg,http://ec2.images-amazon.com/images/I/51bsLAswKVL._SL500_AA280_.jpg";



preg_match_all('#src="(http://ec2\.images-amazon\.com/images/I/[a-z\d]+\._SL500_AA280_\.jpg)"#is',$handle,$m);



print_r($m[1]); 

我是要匹配http://ec2.images-amazon.com/images/I/任意字符._SL500_AA280_.jpg


preg_match_all('#src="(http://ec2\.images-amazon\.com/images/I/[a-z\d]+\._SL500_AA280_\.jpg)"#is',$handle,$m);
这段匹配不了，请问哪里的问题呢？？
------解决方案--------------------
源码中没有 src=" 字符，当然匹配不了。这样写：

preg_match_all('#http://ec2\.images-amazon\.com/images/I/.+?\._SL500_AA280_\.jpg#is',$handle,$m);

 

print_r($m);
