The right function

[Paul C-T]

Hi,

Don't know the right function to use here. I have a php file containing
text only that will contain references to smilies formatted such as "...
then I told him the punch line (wink) ..." - obviously I want to detect the
(xxx) smilie and replace with an image.

I can sort of do this using multiple lines of code like this ...

$mytext= str_replace("(w ink)", "<IMG SRC=\"wink.gif\ ">", $mytext);
$mytext= str_replace("(s mile)", "<IMG SRC=\"smile.gif \">", $mytext);
$mytext= str_replace("(l augh)", "<IMG SRC=\"laugh.gif \">", $mytext);

.... but I would prefer to find a function that could detect the (xxx) and
simply call the relevant image using a variable ... <IMG SRC="$image.gif ">

Any ideas?

Paul.

Are you sure you want to make it unrestricted? You've only got a finite number
of images, surely, so you'd want to just limit it to that. In which case set up
an array, and loop over the array doing str_replaces as above.

$images = array('wink', 'smile', 'laugh');
foreach ($images as $image)
$mytext= str_replace("($ image)", "<IMG SRC='$image.gif '>", $mytext);

If you do want it unrestricted, then preg_replace is probably the direction
you want to go.

str_replace accepts arrays for the first and second parameter...

See example 1 on http://php.net/str_replace (specifically the
pizza/beer/... lines).

So it just appears that you should RTFM :)

Use glob() to scan for these images, then construct a replacement array for
strtr() based on the filenames. That way you can add additional smilies by
simply uploading new images.
