You can just download the source distribution of php, and on a linux
commandline do:
grep -inr preg_replace *
You'll find all occurances of preg_replace, including it's declaratin, which
I have copies below. It seems like it's being passed thru to another
function .. Which is also on the same file: ext/pcre/php_pcre.c (I've
searched a PHP5.0 sourcetree)
1111 /* {{{ proto string preg_replace(mixed regex, mixed replace, mixed
subject [, int limit])
1112 Perform Perl-style regular expression replacement. */
1113 PHP_FUNCTION(preg_replace)
1114 {
1115 preg_replace_impl(INTERNAL_FUNCTION_PARAM_PASSTHRU, 0);
1116 }
1117 /* }}} */

Onderwerp: [PHP] better understanding of ereg_replace and other
functions
Hi everybody,
Lot of places in manual i came across using "ereg_replace" or "ereg" is very
resource intensive and hence its better to use "preg_replace" or
"str_replace" or "strpos" if they do the jobs.
Now i am very curious to look at the source code (implementation) of these
function so as to be able to decide the right choice for me. Can any one of
you tell me where to find the source code of these functions. Do they
require special privileges ??
Please help me out
Binay
