Match after a period?

[JAB Creations]

I'm trying to figure out how to make a regex to match after a period. So the string '24a6g3y5g35635.z' would match 'z'.

$cookie = 'audio.0_backgroundimages._browserpatch.1';

$my_pattern = '/.$/';

list($audio, $backgroundimages, $browserpatch) = split($my_pattern, $cookie);
echo $audio;

The desired match in this instance would be '0'.

Remember that a period in a regex is a special character. If you're looking for a period you need to escape it with a backslash.

Hi there,

Try:

$my_pattern = '/\.(.+)$/';

Let me see if I've got this right...

Your $cookie is 'audio.0_backgroundimages._browserpatch.1' and you want to do a split with the period as your delimiter, and you have three list variables, but you have 4 split instances. So yes as mentioned above you would need to escape the period (I personally like to bracket it, just in case you want more than one delimiter), so I would go:

list($audio, $backgroundimages, $browserpatch) = split('[.]',$cookie);

So in your example:

$audio = 'audio'
$backgroundimages = '0_backgroundimages'
$browserpatch = '_browserpatch'

Is that what you wanted to do? And is this a static format for your strings? Because you could just do a second list function afterwards on $backgroundimages:

list($int,$str) = split('_',$backgroundimages');

That would give you your 0

If you only want to match one character, I would use:

if (preg_match("/\.(.)/",$str,$match))
{
$result=$match[1];
}

Note that I'm not the best at regex though!

I haven't been able to keep up with posts of late due to some goofed XP slipstream installs...

I reference the "sets" in a way like CSS...

property.value
property.value_property.value_property.value_property.value

There are more like a dozen properties and values stored in the cookie. I just shortened it to avoid being obnoxious on the thread by creating a horizontal scrollbar. ;)

All I need the regex to do is get the value of a property. In this instance that value simply is '0' (for the property audio). The goal of course is to echo $audio at the end of all things said and done and have it echo '0', or if you change the 0 in the cookie to 11 then echoing $audio would echo '11'.

I use the dots and underscores because they don't turn in to %20, %35, etc symbols (they're not considered entities I presume so what are they correctly referenced as?)

...any way the . I decided to use to "connect" visually (as this is PHP) for concatenate (not to actually connect them, just a symbolization of sorts). The underscore separates each set.

This also works though it seems somewhat repetitive? But it works! So I'm still interested in the proper regex so I guess this would go a ways to demonstrate the desired effects...

<?php
$cookie3 = 'audio.0_backgroundimages._browserpatch.1_chatroom.0_connection.0_css3.0_cursors.0';
$pieces = explode('_', $cookie3);
foreach($pieces as $val) {
$contents=explode('.', $val);
$$contents[0]=$contents[1];
}
echo '$audio = <b>'.$audio."</b><br />\n";
echo '$backgroundimages = <b>'.$backgroundimages."</b><br />\n";
echo '$browserpatch = <b>'.$browserpatch."</b><br />\n";
echo '$chatroom = <b>'.$chatroom."</b><br />\n";
echo '$connection = <b>'.$connection."</b><br />\n";
echo '$css3 = <b>'.$css3."</b><br />\n";
echo '$cursors = <b>'.$cursors."</b><br />\n";
?>

Any way I'm still interested in the regex which I haven't been able to figure out yet. If this method above however creates less of a load I'd happily use it instead however. Either way the more ways I can figure out how to do any one particular thing would hopefully help me figure out how to change things to make them more efficient later on.

Looking at your example I don't know if I would use a regex but how's this?

$cookie3 = 'audio.0_backgroundimages._browserpatch.1_chatroom.0_connection.0_css3.0_cursors.0'; 
$pieces = explode('_', $cookie3); 
foreach($pieces as $value) { 
list($cat,$val) = split('\.',$value);
echo "$cat = <b>$val</b><br />\n";
} 

That seems to work and use a little less code. Oh well best I could do from what I inferred you needed done.
