Answer 2

你没有防止贪婪匹配。 $pattern='/(<[img|IMG].+?src=\"?.+?)(images\/tmp\/)(.+?\.(jpg|gif|bmp|bnp|png)\"?.+?>)/';

Answer 3

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 = '<p><img src="http://localhost:8080/story/images/tmp/1403530150545.jpg" style="width: 268px;"><img src="http://localhost:8080/story/images/tmp/1403530147265.jpg" style="width: 268px;">test</p>';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;
}
替换后：
<p><img src="http://localhost:8080/story/images/pub/1403530150545.jpg" style="width: 268px;"><img src="http://localhost:8080/story/images/pub/1403530147265.jpg" style="width: 268px;">test</p>
