[RESOLVED] Fetching records from a pattern separated string

[computerzworld]

Hello,
I am having a string with the pattern like,

"test" <[e-mail]>, "test1" <[e-mail]>,"test2" <[e-mail]>, 

I want to separate out the string wrapped in <> (email addresses) in an array. How can I do this? please help me. Thanks in advance.

Hmm.. I'm going make some assumptions here;
a) in your array, all text contained within <....> are email addresses.
b) by separate, you want to simply 'get that information' as the term separate can mean splitting something, which is different.

something along these lines perhaps?

$arr = array('test <[e-mail]>', 'test1 <[e-mail]>', 'test2 <[e-mail]>');
foreach($arr as $val){
    if(preg_match('#<([^>]+)>#', $val, $match)){
        echo $match[1] . "<br />\n";
    }
}

output:

[e-mail]
[e-mail]
[e-mail]

Since the OP stated "I have a string...", I'm going to guess that the solution he/she's after is more like:

$data = '"test" <[e-mail]>, "test1" <[e-mail]>,"test2" <[e-mail]>,';
preg_match_all('/<(.*?)>/', $data, $emails);
$emails = $emails[1];

print_r($emails);

Output:

Array
(
    [0] => [e-mail]
    [1] => [e-mail]
    [2] => [e-mail]
)

Oh right, I see now.. from string to array.. I misunderstood.... my bad..
Then yes, preg_match_all, but it's better to use a negated character class instead of a lazy quantifier, as this is typically faster.

$data = '"test" <[e-mail]>, "test1" <[e-mail]>,"test2" <[e-mail]>,';
preg_match_all('/<([^>]+)>/', $data, $emails);
echo "<pre>" . print_r($emails[1], true);

thanks.. thats what exactly i want.... is there any good resource for learning regular expressions? thanks once again...

You can read up on regex in the php manual, or over at regular-expressions.info.

But my absolute favorite resource for regex undoubtedly comes from the book Mastering Regular Expressions, which I strongly recommend as it delves deep enough into the mechanics of how the regex engines think. It will really help you exploit regex's strengths and avoid some common pitfalls as well.
