parsing <img> tag

[guls_guys]

Hi guys

 

i am new to php and need help in pasrsing img tag

"<img src=\"images/hocnorwich/productInfo.jpg\" alt=\"Sophie Evening Gown\" title=\" Sophie Evening Gown \" width=\"105\" height=\"143\" />"

 

i want to change the width and height of image to 50% of current size

 

so how can i do this possible by parsing the string or making tokens or might be using some regular expressions (which i dont know how to use)

 

and i want to do it in php

 

hope to get a swift answer

 

cheers

Hello,

 

I would use image functions to read the image directly, get the actual width and height, and build the image tag with the height and width set to calculated to 50% of actual size.

thanks mate

 

problem is i dont get the image uploaded directly so i dont get its path

what i get is this variable with the complete img tag

 

so how can i read info from it and build new tag

hi guys

 

found the solution

 

$src=htmlentities($proImg,ENT_NOQUOTES);//$proImg got the string which i want to change

$src = preg_replace( '/(width|height)="\d+"/', '$1="10%"', $src);

echo $src= html_entity_decode($src);

 

Regards
