ereg() is now preg match ?

depricated versions

[Matthew1980]

Hi there people of the forum,

I have just been 'tidying' up some old code, and found that ereg() is now depricated, at least that what php.net has confirmed, my problem is this (intentionally no semi-colon):-

!preg_match("^([a-z]|[0-9]|\.|-|_)+@([a-z]|[0-9]|\.|-|_)+\.([a-z]|[0-9]){2,4}$", $admin_email)

This generates a warning saying:-

No ending delimiter '^' found

Could someone point out where this should be as this isn't my strong suite..

Cheers,
Mrb

I have been eyeing this with alarm for some while, as I have some scripts from years ago that are still packed full of ereg directives.

Hi there g1smd,

Well it was a suprise to me too, I just need to know what's wrong with the pattern in there now, as this worked fine in ereg() & eregi(), but now it generates a warning that wasn't there yesterday! It must have been though, I haven't upgraded to the latest php release, I'm still on 5.3.0, until I need a reinstall ;-p

Cheers,

The pattern needs to be surrounded by a start and end deliminator to separate the pattern from the pattern modifiers.

Try the following:

!preg_match("/^([a-z]|[0-9]|\.|-|_)+@([a-z]|[0-9]|\.|-|_)+\.([a-z]|[0-9]){2,4}$/", $admin_email)

Hi there Eelixduppy,

Great, that's better no errors/warnings. I understand from that, if I was to place an 'i' after the last slash, it would make it case insensitive then? That's the gist I get from the php manual anyway...

Cheers,

Yes, that is correct. There are other modifiers too that allow you to do various things. here's the list if you haven't already found it: [php.net...]

The deprecated warnings for PHP6 were added in PHP5.3 to let developers know what changes are coming in PHP6.
