I fund few posts to explode data as array but mine is bit specific because the data has 2 parts

I have this 

title=Title1|link=Link1
title=Title2|link=Link2

and result I need is this

Array
(
    [0] => Array
        (
            [title] => Title1
            [link] => Link1
        )

    [1] => Array
        (
            [title] => Title2
            [link] => Link2

        )

)

data is coming from texarea separated by \n so the data you see is actual data

thank you!

I'm more a fan of explode() than preg_match() when you don't actually need regular expressions.

<?php

$text="title=Title1|link=Link1\ntitle=Title2|link=Link2";

$result=array();
$count=0;

// line by line...
foreach (explode("\n", $text) as $line) {
  // variable by variable...
  foreach (explode("|", $line) as $vars) {
    // separate LHS from RHS.
    $parts=explode("=", $vars);
    $result[$count][$parts[0]]=$parts[1];
  }
  $count++;
}

print_r($result);

?>

Don't forget to add code to handle lines that don't match the pattern you expect. Input validation is important.

it is a nice one also but preg is much simlper –  Benn Feb 20 '12 at 4:47
    
Nice to see comments in code. And +1 for code that actually works and also returns precisely the output that the OP asked for. –  Graham Feb 20 '12 at 4:50
    
actually much cleaner and sorted , thank you! will come handy –  Benn Feb 20 '12 at 4:50
    
I just had to change the answer to yours , this is what I call clean coding, many thanks! –  Benn Feb 20 '12 at 4:51
    
You're very welcome. Kudos to @Czechnology though for coming up with a one-liner that got you 90% of the way! –  ghoti Feb 20 '12 at 4:57

preg_match_all('~^title=(.+)\|link=(.+)$~m', $text, $reg, PREG_SET_ORDER);

print_r($reg) produces

Array
(
    [0] => Array
        (
            [0] => title=Title1|link=Link1
            [1] => Title1
            [2] => Link1
        )

    [1] => Array
        (
            [0] => title=Title2|link=Link2
            [1] => Title2
            [2] => Link2
        )

)

I'm sure you can easily modify that to fit your required schema.

sorry but I don't see how it produces and array i set $text as the data I have and print_r outputs 1 –  Benn Feb 20 '12 at 4:07
    
I agree that preg_match may be a very good option for this. –  Shea Feb 20 '12 at 4:10
    
ok can you please use example I gave , for example ,, $data ="title=Title1|link=Link1\ntitle=Title2|link=Link2"; –  Benn Feb 20 '12 at 4:12
    
@Benn, the output array is in $reg. See print_r($reg) (or - if you need to capture the output of print_r, use $str = print_r($reg, true)). –  Czechnology Feb 20 '12 at 4:12
    
nailed it brother! thank you! –  Benn Feb 20 '12 at 4:15

Maybe something like this, it's a bit verbose but you should be able to use it as the basis for something more elegant.

<?
$result=array();

foreach ($line in $iterable_variable_with_one_line_per_iteration){
    $subresult=array();
    foreach ($kv_pair in explode($line,"|")){
          $kv_pair_2 = explode($kv_pair,"=");
          $subresult[kv_pair_2[0]]=$kv_pair_2[1];
    }
    array_push($result,$subresult);
}
?>
