Removing IMG tags

[MikeDXUNL]

say I have this stored in a variable:

 

$var = "<img src="/NR/somefolder/onemorefolder/thisimage.jpg" alt="Some ALT Text" width="85" height="120" />";

 

how can I remove the tag to retrieve only:

/NR/somefolder/onemorefolder/thisimage.jpg

This is pretty dirty, but it works provided they're all formatted the same way.

 

$words = explode('=',$var);
$words2 = explode('"',$words[1]);
echo $words2[1];

 

No idea if there's an easier/better way of doing it.

class ImageTags {
   protected static $src;
   public function parse($string) {
           if (preg_replace('/<img src="(.+)"(.*) \/>/Usie', "ImageTags::StoreSource('$1')", $string)) {
                         return TRUE;
           }
           else {
                        return FALSE;
          }
   }
   public static function StoreSource($src) {
         self::src[] = $src;
         reset($src);
   }
   public function getSource($elem=NULL) {
          if ($elem == NULL) {
               $currsrc = current($this->src);
               next($this->src);
              return $currsrc;
          }
         else {
              return $this->src[$elem];
         }
   }
}

 

At least that's how I'd probably do it.           

Usage:

$imgtag = new ImageTags();

if ($imgtag->parse($var)) {

       $src = $imgtag->getSource();

}

else {

       echo "\$var contained no img tags.";

}

 

EDIT: Forgot next() in the getSource function.

EDIT 2: Fixed missing function declaration and error in static function. =X

EDIT 3: Wow, another typo.  I'm so tired. =X

LOL found another mistake.  And it won't let me edit that post.  Sorry.  Here you go:

EDIT AGAIN: Finally fixed. Sorry about that.

 

class ImageTags {
    protected static $src = array();
    public function parse($string) {
            if (preg_replace('/<img src="(.+)"(.*)\/>/sie', "ImageTags::StoreSource('$1')", $string)) {
                          return TRUE;
            }
            else {
                         return FALSE;
           }
    }
    public static function StoreSource($src) {
          self::$src[] = $src;
          reset(self::$src);
          return $src;
    }
    public function getSource($elem=NULL) {
           if ($elem == NULL) {
               $currsrc = current(self::$src);
               next(self::$src);
               return $currsrc;
           }
          else {
               return self::$src[$elem];
          }
    }
}

 

At least that's how I'd probably do it.           

Usage:

$imgtag = new ImageTags();

if ($imgtag->parse($var)) {

       $src = $imgtag->getSource();

}

else {

       echo "\$var contained no img tags.";

}

You know, I'm actually going to make an HTML tag-parser class this weekend.  That ImageTags class now works properly.

 

I just did:

<?php
class ImageTags {
    protected static $src = array();
    public function parse($string) {
            if (preg_replace('/<img src="(.+)"(.*)\/>/Usie', "ImageTags::StoreSource('$1')", $string)) {
                          return TRUE;
            }
            else {
                         return FALSE;
           }
    }
    public static function StoreSource($src) {
          self::$src[] = $src;
          reset(self::$src);
          return $src;
    }
    public function getSource($elem=NULL) {
           if ($elem == NULL) {
               $currsrc = current(self::$src);
               next(self::$src);
               return $currsrc;
           }
          else {
               return self::$src[$elem];
          }
    }
}
$img = new ImageTags();
$var = '<img src="lol.png" alt="Rofl" />';
if ($img->parse($var)) {
      echo $img->getSource();
}
else {
      echo "Nope.";
}
echo "\n<br />";
?>

 

And it output "lol.png".
