Don't return Parathesis content

[Garethp]

Ok, so I'm getting a little better at regex then when I first started (Before I knew what .*? mean XD) and I'm wondering this. Say I use

 

preg_math('/[0-9]*? ([A-Za-z]*)/', $SomeStrings, $Matches);

 

On a series of strings where it matches that, how do I get it to NOT have the [A-Za-z] part in $Matches?

[.josh]

that can be interpreted at least 3 different ways.  I heard a rumor that the more specific you are about your question, the more likely people are going to (?:be able to)? help you.

 

1) match but not capture

change that part to (?:[A-Za-z*)

 

2) match anything but that (negated char class)

change that part to ([^A-Za-z*)

 

3) not look for it at all

remove it from your pattern

Simply remove the parentheses. They're the ones capturing the match. If you need to group part of the pattern without capturing the match (e.g. when using alternations), you can use non-capturing parentheses (?:pattern)

 

And CV beat me to it, but in turn I didn't interpret it in more than one way. lol

Awesome. Next question. Say I have

 

preg_match('/(?:Some ([0-9]*) Text)|(?[0-9]*) Some Text)/', $SomeString, $Matches);

 

it'll match Some 11 Text or 11 Some Text, but if it's Some 11 Text, the 11 with be stored in $Matches[1] while if it's 11 Some Text, the 11 will be stored in $Matches[2] and $Matches[1] will be blank. How do I make it so that the 11 in Some 11 Text will only back reference if that the rest of the string in (?:Some ([0-9]*) Text) matches. So basically I want 11 to be stored in $Matches[1] for both strings

[.josh]

well..this is what I came up with.  Though the number will appear in $Matches[2] either way, not $Matches[1]

preg_match('/(?:(Some )?([0-9]*)(?(1)| Some) Text)/', $SomeString, $Matches);

[.josh]

You know, I'm also wondering if we are making this more complicated than it needs to be.  Is the goal here to extract a number from a string, regardless of where that number is? Is there a reason you can't just do

 

/[0-9]+/

 

?

 

It would help if you actually posted an example of the actual content.

[Garethp]

This is my actual code

 

<?php

header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past

$NamePattern = '/(?:\[DATS\] Ryuusei no Rockman \- ([0-9]{1,})(?:v2)? (?:\[FINAL\])?\[XviD\]\[[0-9a-zA-Z]*\])|(?[0-9]*))/';
$WikiPattern = '';

//preg_match_all($WikiPattern, $result, $WikiMatch);

//Put these into an array here

//Open images directory
$dir = dir("Wiki");

//List files in images directory
while (($file = $dir->read()) !== false)
{
if($file == "." || $file == "..")
	{
	continue;
	}

if(preg_match($NamePattern, $file, $M))
	{
	//echo $file;
	print_r($M);
	}

else
	{
	//echo "<s>" . $file . "</s>";
	}
echo "<br>";
}

$dir->close();

//echo $result;
?>

 

Basically, it's meant to take all the file names of downloaded anime, which I have yet to rename, fetch a page with the list of their episode names (going to put that in later) and then assign those names to them automatically based on the episode number in the file name. Here are the names that I have to work with

I might be making it a little too complicated, but basically I want it to be a flexible script, so that I can use it to rename any TV Show or Anime automatically by just changing the Patterns.
