I'm trying to make a simple bbcode system, but I'm having a little issue with inserting a variable from the regexp expression into an array.
Here's the code:
$font_sizes = array(1 => 9,
2 => 13,
3 => 15,
4 => 17,
5 => 21,
6 => 26,
7 => 36 );
$pattern[2] = '#\[size="(.+?)"\](.+?)\[/size\]#is';
$replacements[2] = "[size={$font_sizes['$1']}]$2[/size]";
$post = preg_replace($pattern, $replacements, $post);
As you can see, I want size used in the bbcode to change based on the array. But the I can't get it working in this line:
$replacements[2] = "[size={$font_sizes['$1']}]$2[/size]";
Anyone got any ideas?
Thanks in advance,
Mark.

Hi there marked,
Remove the single quotes from around the quoted variable... '$i' to just $i
Hope that helps :)
I would post the code but it keeps coming up error when I try to post :(
Cheers,

Thanks for you reply,
I tried that before, as well as many other variations. Without the single quotes I get this error: Parse error: syntax error, unexpected T_LNUMBER, expecting T_VARIABLE or '$'

Hi there marked,
Oop's try this then, I hadn't noticed this on first read ;0
{".$font_sizes[$i]."}
The forum software won't let me post the code so just try replacing everything bewteen the braces as I have suggested. ;-p
This looks like you are trying to add the $font_sizes var to a string, in which case, that should now be fine, other than that I am stumped - it's too hot to think straight!
Cheers,
MRb
