1) There was no PCRE library when I first added regex support to PHP.
Henry Spencer's regex library, although not my initial choice, was
chosen because that is what came bundled with Apache.
2) The ereg_* functions implement the Posix 1003.2 extended regular
expression standard. The same regular expressions found in the
Unix command line utils like grep, egrep and fgrep. The preg_*
functions support the perverted Perl-style regular expressions.
3) Removing the ereg_* functions would cause a backward compatibility
nightmare. Thousands, if not hundreds of thousands of scripts out
there would have to be converted.
4) If you are using Apache you already have the library linked in anyway.
Removing PHP support wouldn't save you any "bloat". Not that this
"bloat" is at all significant on any modern OS with shared pages.
