[Resolved] Breaking a string and replacing elements

ajna

I am trying to use a complex pattern to create an image link -- rather than insert an html line of code into my table, I want to enter something like:

[swallowshirt.gif;154;96;left]

I then want to locate these entrys in a text entry and pull the elements out for use in an img src link that will replace the bracketed info in my text data.

I was looking at using preg_replace but have gotten totally lost.

Does anyone have any ideas or could you point me in the right direction?

Thanks!

Kev

$string = 'swallowshirt.gif;154;96;left';

$explode = explode(';', $string);
$image_tag = '<img src="' . $explode[0] . '" width="' . $explode[1] . '" height="' . $explode[2] . '" align="' . $explode[3] . '">';

echo $image_tag;

Thanks for the help -- but that didn't really help me with finding different instances of the pattern in a larger block of text. I found a different approach and I am now using the following -- works like a charm.

$tags=array
(
'#[img=(.?)](.?)[/img]#msi' => '<img src="'.$images_path.'\1" hspace="5" vspace="5" align="\2">'
);

$bodytext=preg_replace(array_keys($tags), array_values($tags), $bodytext);

Going to play around with patterns a bit to throw more variables in as needed.

Thanks for the help tho -- I am sure it will come in handy.
