I think, I found the missing point. In your last example, you had an 'e' at the end of your regular expression (after the final #) which was missing in your first examply. I guess, this is doing the eval() job.

I still don't know exactly, what your problem is.

You are right, despite the ' ' around your function, the content gets eval()ed.

Now let's try this

$text=preg_replace('#\[x\](.*?)\[/x\]#e', "imagize('$1')", $text);

so that the $1 will be translated instead of taken literally.

I am able to execute and see the values with this line

<h5><?php $text= "[x]druvans@gmail.com[/x]"; $text=preg_replace('#\[x\](.*?)\[/x\]#e','imagize(\'$1\')',$text); echo $text;  ?></h5

I still cldnt figure out, how to integrate it to bbcode

you might try to change your code in something like:

$text = preg_replace("#\[x\](.*?)\[/x\]#", imagize($1), $text);

but I'm not sure, whether it works out for you. I have never used a function inside a preg_replace(), so I really don't know about it. If this doesn't work you might choose an iterative approach replacing one email address after the other. A third variant would be to apply your differently modified $text to the eval() function.

There is at least one more source for trouble in your imagize() function, that I found at a first glance. You use only the first part of the email address to determine the filename, so if you have two people with info@domain1.com and info@domain2.com they both will show up with the info.png image which serves for domain2.com.

I created a function called imagize, which basically converts the given text into a png image file, then returns the file name. This part works OK.

Now, I added all this to parser.php file and   

$text = preg_replace("#\[x\](.*?)\[/x\]#", "imagize('$1')", $text);

==>  imagize('druvan@gmail.com')

I am not able to execute  'imagize' function, can someone help me.

Result  <img src=imagize('$1') />
