[SOLVED] How to remove [img] and [/img] tag

[lily]

Hi, I need to find the images from some text. The images are coded within tags (I purposely put a space between img and ], so that you can see the tags). I have found a way to take off tag if there is no other text in string.

For example:

$RawBody=""

$RawBody=preg_replace("#\[img\]([^?\['\"]+?)\.(gif|png|jpg|jpeg)\[/img\]#i", '\1.\2 ',$RawBody);

 

I will get image name: myimage.jpg. But if there is other text in $RawBody, then I can not get right result. For example, if I change $RawBody to:

$RawBody="This is my image , other text";

$RawBody=preg_replace("#\[img\]([^?\['\"]+?)\.(gif|png|jpg|jpeg)\[/img\]#i", '\1.\2 ',$RawBody);

 

I will not be able to get result "myimage.jpg". What to do to get right image name in second case? Thanks for help!

Couldn't you just use str_replace?  You are just trying to remove the two tags and leave everything between? 

 

$RawBody = str_replace("[img ]","",$RawBody);

$RawBody = str_replace("[/img ]","",$RawBody);

Thanks for reply, fanfavorite,

But I need to remove all text befor too. if

$RawBody="text, , other text";

 

I only need result "image.jpg", nothing else. Do you know what to do?

Thanks again.

Try this:

 

$RawBody="text, , other text";

$ini = strpos($string,"[img ]");

$ini += strlen("[img ]"); 

$len = strpos($string,"[/img ]",$ini) - $ini;

$newstring = substr($string,$ini,$len);

echo $newstring;
