Question

For e.g. we have string

$somestring = '11;11;11;12;13';

and array

    $somearray = array(
  11 => array(
    prop => array(0=>11),
    uid => 1,
  ),
  21 => array(
    prop => array(0=>12),
    uid => 2,
  ),
  32 => array(
    prop => array(0=>11),
    uid => 1,
  ),  
  34 => array(
    prop => array(0=>11),
    uid => 2,
  ),  
 35 => array(
    prop => array(0=>13),
    uid => 1,
  ),  
  36 => array(
    prop => array(0=>13),
    uid => 3,
  ),  
  37 => array(
    prop => array(0=>12),
    uid => 1,
  ),  
  38 => array(
    prop => array(0=>12),
    uid => 3,
  ),  
  39 => array(
    prop => array(0=>12),
    uid => 1,
  ),
);

How to get from $somearray [uid] on condition that value of [prop] is equal same value in $somestring and output it by filled rows like this:

row1:11(uid:1);11(uid:1);11(uid:2);12(uid:2);13(uid:1)
row2:11(uid:);11(uid:);11(uid:);12(uid:1);13(uid:3)
row3:11(uid:);11(uid:);11(uid:);12(uid:3);13(uid:)
row4:11(uid:);11(uid:);11(uid:);12(uid:1);13(uid:)

I found a bit reletive solution here http://eval.in/6816 but it is not dealing with repeated values

Just copy it and execute,

<?php
error_reporting(0);
$somestring = '11;11;11;12;13';

$somearray = array(
  11 => array(
    prop => array(0=>11),
    uid => 1,
  ),
  21 => array(
    prop => array(0=>12),
    uid => 2,
  ),
  32 => array(
    prop => array(0=>11),
    uid => 1,
  ),  
  34 => array(
    prop => array(0=>11),
    uid => 2,
  ),  
 35 => array(
    prop => array(0=>13),
    uid => 1,
  ),  
  36 => array(
    prop => array(0=>13),
    uid => 3,
  ),  
  37 => array(
    prop => array(0=>12),
    uid => 1,
  ),  
  38 => array(
    prop => array(0=>12),
    uid => 3,
  ),  
  39 => array(
    prop => array(0=>12),
    uid => 1,
  ),
);

$sme_array    = explode(";",$somestring);
$somestrarray = array_unique($sme_array);
$res          = array();
foreach($somearray as $key=>$val){

    foreach($somestrarray as $value){
        if($val['prop'][0] == $value){
           $res[$value][]   = $val['uid'];
        }       
    }
}

$cnt_values  = array_count_values($somestrarray);

$num_loop    = 1;
foreach($cnt_values as $key=>$val){
  $num_loop  = (count($res[$key])/$val) > $num_loop?(count($res[$key])/$val):$num_loop;
}

for($i=0; $i<$num_loop; $i++){
    echo "row".($i+1).":";
    foreach($sme_array as $vals){
      if(array_key_exists($vals,$res)){
      echo $vals."(uid:".$res[$vals][0].");";
      array_shift($res[$vals]);
      }
    }
    echo "<br>";
}
