php preg_match_all combined with str_replace to replace all img_PHP tutorials in the content

img match php replace str content return picture replace of combine collection

There are a lot of javascript scripts and useless information in the collected image img tags. You must replace what you want, such as alt. Let’s take a look at the content to be filtered first. I copied it casually:

Copy code The code is as follows:

sdfsdfsdf“3568df.com500){this.resized=true; this.style.width=500;}”>sfsdfsdfasdfsadf”3568df.com500){this.resized=true; this.style.width=500;}”>sdfsadf”3568df.com500){this.resized=true;this.style.width=500;}”>sdfsdf

Replace the above into the following shape:
Copy code The code is as follows:

”My where src=”http://www.xxx.com /upimg/080330 /120D1232295023X0.gif” src=”http://www.xxx.com/upimg/080330 /120D1232295023X0.gif” This address should be retained because the pictures use the source address

The method is roughly: first read all the IMG tags in the content, then extract the SRC of each IMG tag, combine it into its own content, and finally replace it.
preg_match_all is the function I want. It can create a three-dimensional array of content matched by regular expressions. You can traverse, search and replace them. If you don’t know much about it, please check the manual. I won’t introduce it in detail here. Function code:
Copy code The code is as follows:

function replace($str)
{
preg_match_all( ”/]+>/isU”, $str, $arr);
for($i=0,$ j=count($arr[0]);$i<$j;$i++){
$str = str_replace($arr[0][$i],””My",$str);
}
return $str;
}
