In the function ucsmart() posted by ieure at php dot net on 04-Dec-2005 11:57, I found a similar problem in this function to what he found in igua's.
<?php
function ucsmart($text)
{
return preg_replace('/([^a-z]|^)([a-z])/e', '"$1".strtoupper("$2")',
strtolower($text));
}
?>
"igua's code adds a backslash in front of the first single quote for me. This doesn't alter the content in any way other than changing case."
Actually, it did end up changing the content for me (php 5.0.4) in the way that this function escapes a single quotation (apostrophe) in the MIDDLE of a word.
For example:
who's online?
Became:
Who\'s Online?
The fix is simple however, and merely requires fine-tuning the regular expression:
<?php
function ucsmart($text)
{
return preg_replace('/([^a-z\']|^)([a-z])/e', '"$1".strtoupper("$2")',
strtolower($text));
}
?>
(note: while previewing this note before adding it, I am noticing php's website is not correctly displaying the change I made as I wrote it. After the first a-z in the expression, the single quotation should be escaped... If it isn't you will get a parse error! And apoligies if my text here is colored as php code; not my fault!)
This will not escape a single quotation mark which occurs in the middle of a word... Though, you may find that might need to add other characters inside the regular expression if you use other special characters inside your words and if you get funky output.
It's a great expression though! Simple, yet very powerful. Kudos!
