Question

php 正则替换img src

我这里写了个，你们运行下看看：

$str = '<center><img src="/ueditor/php/upload/image/20180118/1516250192768590.jpg" title="1516250192768590" alt="20160822181735.jpg"></center>';

$str=preg_replace('/<img.+(src="?)\/ueditor\/(.+\.(jpg|gif|bmp|bnp|png)\"?)>/i',"/upload/ueditor/\${2}",$str);

echo $str;
======怎样去掉：title和alr ====
目前问题就是， 这2个属性干不掉：title="1516250192768590" alt="20160822181735.jpg"

Answer 1

应该这样就可以了：

$str = '<center><img src="/ueditor/php/upload/image/20180118/1516250192768590.jpg" title="1516250192768590" alt="20160822181735.jpg"></center>';
$str=preg_replace("/<img.+(src=\"?)\/ueditor\/(.+\.(jpg|gif|bmp|bnp|png)?)(\".*?title.*?alt.*?)\>/i","<img src=\"/upload/ueditor/\${2}\">",$str);
echo $str;

这样得到的HTML代码为：

<center><img src="/upload/ueditor/php/upload/image/20180118/1516250192768590.jpg"></center>

这应该是你想要的结果哦
