你没有防止贪婪匹配。
$pattern='/(<[img|IMG].+?src=\"?.+?)(images\/tmp\/)(.+?\.(jpg|gif|bmp|bnp|png)\"?.+?>)/';
你写的方法加一个参数U就可以了。
加上U,将懒惰匹配 变成 贪婪匹配。
$pattern='/(<[img|IMG].+src=\"?.+)(images\/tmp\/)(.+\.(jpg|gif|bmp|bnp|png)\"?.+>)/ U';
测试例子:
$content = 'test
';replace_img_publish_path($content);function replace_img_publish_path($content){ $pattern='/(<[img|IMG].+src=\"?.+)(images\/tmp\/)(.+\.(jpg|gif|bmp|bnp|png)\"?.+>)/U'; $replacement="\${1}images/pub/\${3}"; print preg_replace($pattern, $replacement, $content); exit;}
