Re: [PHP] regular expressions question
The + requires at least one character.
The * is "0 or more" characters.

What you tried only requires ONE a-z character somewhere in the input.
Try this:
preg_match('^[a-z]+$', $fname);
This will:
^ "anchor" the string at the beginning
[a-z]+ a to z, with at least one letter
$ "anchor" the string at the end
Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.
Oh, and the digit 3, for "bo3b" who was a programmer on the first
Apple Macintosh. His parents were hippies, and that really is his

What you tried only requires ONE a-z character somewhere in the input.
Try this:
preg_match('^[a-z]+$', $fname);
This will:
^ "anchor" the string at the beginning
[a-z]+ a to z, with at least one letter
$ "anchor" the string at the end
Note, however, that some people have other characters in their first
name, such as apostrophe, space, and dash.

[PHP] regular expressions question
Hi,
Is there any way to limit the user to a set of characters for example say i
want my user to enter any character between a and z (case insensitive). And if
the user enters just one letter not belonging to [a-z], this will not be
accepted.
I tried eregi('[a-z]', $fname) but this allows the user to enter abdg4512kdkdk
for example.
Thank you

Re: [PHP] regular expressions question
If I understand you correctly, I think you want this?
$matches = array();
$test = "(this)example";
preg_match("/\((.*)\)(.*)/", $test, $matches);
array_shift($matches);

[PHP] regular expressions question
I have a little question. I'm having some difficulty with regular expressions: here it is: (this)example should be output in an array [0]=> this [1]=> thisexample I'm supposing this should be done with preg_grep, but I'm not really familiar with some of it's syntax for the regular expression. I could use some ideas, cheers, Simon
