Re: [PHP] Using eregi_replace()

http://php.net/manual/en/ref.pcre.php :
... Since PHP 4.0.4, you can also use Perl-style (), {}, [],
and matching delimiters. ...
the reason you use delimiters is so that you can use PREG modifiers after
the last delimiter, but still inside the expression. read up in the manual,

full ACK :)

Re: [PHP] using eregi_replace to replace only substrings -- not the entire string.
On Tue, 14 Aug 2001 12:23, Kurt Lieber wrote: I'm trying to update a number in a text file using eregi_replace. The original line is: $registrationLimit = 100; and I'd like to change it to: $registrationLimit = 300; now, 100 appears multiple times throughout the file, so I have to match on the whole string, not just 100. I used the following code: (this may wrap in your mail client) $contents = eregi_replace(registrationLimit = ([0-9]+);,registrationLimit = . $form_registrationLimit . ;,$contents); which works, but I'd like to find a more elegant way to do this, rather than rebuilding the entire string. I tried: $contents = eregi_replace(registrationLimit = ([0-9]+);,\\1$form_registrationLimit,$contents); but that only produces: $100300 (in other words, it combines the two values and strips out the registrationLimit = part...) After reading the manual, I understand why, but I'm hoping there's some similar such method where I can parenthesize a substring in the string pattern and then replace only that substring with my replacement string.
