Making array from sentence

I've got this sentence from database

0| Future plan 1| Low 2| Normal 3| High 4| Highest

And I've need to make it look similar to:

[0] => Future plan
[1] => Low
[2] => Normal
[3] => High
[4] => Highest

I cant find any thread, similar to this. Help please.

@ankhzet pointed out a flaw which this answer covers.

<?php
$v              = '0| Future plan 22 2| Normal 123| Low 3| High 4| Highest';
$arraySplit     = preg_split("/([0-9]+)\|/", $v, -1, PREG_SPLIT_DELIM_CAPTURE);
$arrayResult    = array();
for($i = 1; $i < count($arraySplit); $i+=2){
    $arrayResult[$arraySplit[$i]] = $arraySplit[$i+1];
}
pre($arrayResult);
?>

New output:

Array
(
    [0] => Future plan 22
    [2] => Normal
    [123] => Low
    [3] => High
    [4] => Highest
)

OLD

This method will maintain the ID's and is shorter than @ankhzet's answer. Here if you need it:

preg_match_all("/(\d+)\|([^0-9]+)/", $v, $array);
$array = array_combine($array[1], $array[2]);
pre($array);

Output looks like this:

Array
(
    [0] =>  Future plan 
    [2] =>  Normal 
    [1] =>  Low 
    [3] =>  High 
    [4] =>  Highest
)

FYI, pre() is just a function the wraps print_r() inside <pre></pre> tags.

REGEXP, suggested by @Epodax won't keep indexes:

$v = '0| Future plan 2| Normal 1| Low 3| High 4| Highest';
$array = preg_split("/[0-9]+\|/", $v, -1, PREG_SPLIT_NO_EMPTY);

dump($array);
// array:5 [▼
//   0 => " Future plan "
//   1 => " Normal "
//   2 => " Low "
//   3 => " High "
//   4 => " Highest"
// ]

If that matters, probably better be to use this:

$v = '0| Future plan 2| Normal 1| Low 3| High 4| Highest';
$v .= '0|';
$r = [];
while ($v) {
  if (!preg_match('/(\d+)\|(.+?)(?:(\d+)\|)/', $v, $m, PREG_OFFSET_CAPTURE))
    break;

  $idx = intval($m[1][0]);
  $r[$idx] = trim($m[2][0]);

  if (($offset = $m[3][1]) >= strlen($v))
    break;

  $v = substr($v, $offset);
}

dump($r);
// array:5 [▼
//   0 => "Future plan"
//   2 => "Normal"
//   1 => "Low"
//   3 => "High"
//   4 => "Highest"
// ]

I found something that SHOULD do the trick for you: preg_split

$string = "0| Future plan 1| Low 2| Normal 3| High 4| Highest";
$array = preg_split("/[0-9]+\|/", $string, -1, PREG_SPLIT_NO_EMPTY);

Use explode

$words = preg_replace('/[0-9]+/', '', $string);//remove all numbers from string
$array = explode ("|" , $words);
$array2 = array_filter($array)//remove empty elements

Given that in your string you have |, I made the following (extra checks must be made):

$string = '0| Future plan 1| Low 2| Normal 3| High 4| Highest';
$string = str_replace('|','',$string); //replace |
$length = strlen($string); //get length
for($i=0; $i<=$length-1;$i++)
{
    if(is_numeric($string[$i])) { //get numbers
        $word[$string[$i]] ='';
        $lastIndex = $string[$i]; //save last found
    } else {
        if($string[$i]!=' ') { //if not space append to array element of last number found
            $word[$lastIndex] .= $string[$i];
        }
    }
}
var_dump($word);

array (size=5)
  0 => string 'Futureplan' (length=10)
  1 => string 'Low' (length=3)
  2 => string 'Normal' (length=6)
  3 => string 'High' (length=4)
  4 => string 'Highest' (length=7)

First change database sentence and then in your case use php function explode ("| " , $string). This function can explode the string to array by delimiter.

try this:

<?php
   $str = "Future plan | Low | Normal | High | Highest";
   print_r (explode("|",$str));
?>
