Re: [PHP] regexps
I need to use regular expressions, but i found that the current Perl-compaitable API unuseful in my case, infact i need to get the positions of every match to the pattern and i found nothing in the Manual that does so, does any one know a way to do this (the only one i found is specific to PHP 4.3.0) You could match all of the strings and then use one of the other string functions to find the position. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] regexps
using any of the string functions on the output would ofcourse cause a performance drawback (do you agree with me?), i had used a combination of string functions to do instead of regexps, which one will be faster as you think ? where can i suggest such a function on the current regexps API ?

It depends on exactly what your doing, how much text you have, and why you need to match the position as well as the text. where can i suggest such a function on the current regexps API ?

Hi,
i made some basic bench and see that it really depends...
try to make some basic search like ^[0-9]{1,4}$
how can u do this ? with substr, strlen, strstr and ifthenelse ?
i found really faster to use preg_match(), which is really faster
than if (ereg())...

RE: [PHP] regexps
here are two regexps that might do what you want
\w matches alphanum (1-9a-zA-z)
IMO, the best way to check for non-alphanum chars is
to check for \W (upper case is negation of alphanum,
which will match only non-alphanum).
if (preg_match('/^\w+$/', $data)) {
print entirely alphanum
}
if (preg_match('/\W+/', $data)) {
print Contains non-alphanum!!;
}

i need to find out if a string (user imputed) conatins numbers. I want
only a-zA-Z to be in a field. (their name for exampleand city)...i
have the following however my regexps are VERY weak as i am a beginner.
function validatetext($text){
if (is_string($text)== 1){
return good;
}else{
return bad;
}

Don't forget that zero and underscore! IMO, the best way to check for non-alphanum chars is to check for \W (upper case is negation of alphanum, which will match only non-alphanum). Yep, works nicely as long as including the underscore as one of the alphanumeric character is acceptable for your purposes. -- CC -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Why don't you do a function with an ereg inside? I don't think that exist a command like that... Rom - Original Message - From: Elliot L.

Re: [PHP] regexps
Most of the preg_ functions support arrays of values as input parameters. It's all in the documentation. "Elliot L.

Re: [PHP] regexps
You could loop it with foreach (which I think is the same way Perl handles
the ex you gave).
foreach ($myArr as $myStr) {
$myStr = ereg_replace($regexp, $myStr);
}
Note quite "one statement", but if you really wanted to shorted it (and in
the opinion of most sacrafice readability), you could say:
foreach ($myArr as $myStr) $myStr = ereg_replace(...etc...);
