I liked jesdisciple's approach to a camel case function, but needed something a little more
high powered, so here is my stab at this need:
<?php
/**
* Convert a string to camel case, optionally capitalizing the first char and optionally setting
which characters are
* acceptable.
*
* First, take existing camel case and add a space between each word so that it is in Title Form;
note that
* consecutive capitals (acronyms) are considered a single word.
* Second, capture all contigious words, capitalize the first letter and then convert the rest into
lower case.
* Third, strip out all the non-desirable characters (i.e, non numerics).
*
* EXAMPLES:
* $str = 'Please_RSVP: b4 you-all arrive!';
*
* To convert a string to camel case:
* strtocamel($str); // gives: PleaseRsvpB4YouAllArrive
*
* To convert a string to an acronym:
* strtocamel($str, true, 'A-Z'); // gives: PRBYAA
*
* To convert a string to first-lower camel case without numerics but with underscores:
* strtocamel($str, false, 'A-Za-z_'); // gives: please_RsvpBYouAllArrive
*
* @param string $str text to convert to camel case.
* @param bool $capitalizeFirst optional. whether to capitalize the first chare (e.g.
"camelCase" vs. "CamelCase").
* @param string $allowed optional. regex of the chars to allow in the final string
*
* @return string camel cased result

function strtocamel($str, $capitalizeFirst = true, $allowed = 'A-Za-z0-9') {
return preg_replace(
array(
'/([A-Z][a-z])/e', // all occurances of caps followed by lowers
'/([a-zA-Z])([a-zA-Z]*)/e', // all occurances of words w/ first char captured
separately
'/[^'.$allowed.']+/e', // all non allowed chars (non alpha numerics,
by default)
'/^([a-zA-Z])/e' // first alpha char
),
array(
'" ".$1', // add spaces
'strtoupper("$1").strtolower("$2")', // capitalize first,
lower the rest
'', // delete undesired chars
'strto'.($capitalizeFirst ? 'upper' :
'lower').'("$1")' // force first char to upper or lower
),
$str
);
}
