Problem on displaying Array elements

[allinurl]

I have an array that looks like the ex below, what I want to do is just get one element of its kind, for instance just get: JRA, JRB and not the rest of the repeated values.

Currently Im running throughout the whole array but it is not the way I want it.

 

  $data = array( array("CRA", 'First', 790, $name), array("CRB", 'Third', 721, "Yes"), array("CRA", 'Second', 721, "Yes"), array("CRA", 'Fifth', 721, "Yes"), array("CRB", 'Fout', 721, "Yes"));
  $lines = count($data);

   for($i = 0; $i < $lines; $i++){
        if(substr($data[$i][0], 0, 2) == 'CR'){ 
   	if(substr($data[$i][0], 0, 3) != substr($data[$i+1][0], 0, 3)){
	$cra = '<h3>TEST ' . substr($data[$i][0],2).'</h3>'; 
	print $cra. '<br />'; 
         }
      }
   }

 

Results should be only these two: TEST A TEST B

 

 

Could somebody give me some hints on this? Thanks in advance

Using a foreach loop like the following seems to work:

<?php
$sav = array();
foreach ($data as $arys) {
        if(substr($arys[0], 0, 2) == 'CR')
	  		if (!in_array('TEST' . substr($arys[0],2,1),$sav))
				$sav[] = 'TEST' . substr($arys[0],2,1);
   }
echo implode("<br>\n",$sav);
?>

Thanks for ur reply. Would this be possible by not creating a new array?, I was thinking more like keeping the same values of the original array, more like sorting it and then doing the !=. So far the way I posted works for me just fine but not when the values are not sorted I was trying to sort them out but I keep getting the same values. Here it is the algorithm that Im using, when I do a print_r I got them sorted, but when they go through the loop it comes out in the same way. What Am I missing? Thanks again

 

<?php
  $data = array( array("CRA", 'First', 790, $name), array("CRB", 'Third', 721, "Yes"), array("CRA", 'Second', 721, "Yes"), array("CRA", 'Fifth', 721, "Yes"), array("CRB", 'Fout', 721, "Yes"));

  $SortOrder=1; // desc by default , 1- asc
  $newdata = sortByField($data,'0',$SortOrder);
  $lines = count($data);

  print '<pre>';
  print_r($newdata); // here it comes sorted good
  print '</pre>';

   for($i = 0; $i < $lines; $i++){
        if(substr($newdata[$i][0], 0, 2) == 'CR'){ 
   	if(substr($newdata[$i][0], 0, 3) != substr($newdata[$i+1][0], 0, 3)){
	$cra = '<h3>JUST TEST PRINT ' . substr($newdata[$i][0],2).'</h3>'; 
	print $cra. '<br />';  // here comes out same way, like not been sorted... 
         }
      }
   }

function sortByField($multArray,$sortField,$desc=true){
$tmpKey='';
$ResArray=array();

$maIndex=array_keys($multArray);
$maSize=count($multArray)-1;

for($i=0; $i < $maSize ; $i++) {

$minElement=$i;
$tempMin=$multArray[$maIndex[$i]][$sortField];
$tmpKey=$maIndex[$i];

for($j=$i+1; $j <= $maSize; $j++)
	if($multArray[$maIndex[$j]][$sortField] < $tempMin ) {
	$minElement=$j;
	$tmpKey=$maIndex[$j];
	$tempMin=$multArray[$maIndex[$j]][$sortField];

	}
	$maIndex[$minElement]=$maIndex[$i];
	$maIndex[$i]=$tmpKey;
}

if($desc)
for($j=0;$j<=$maSize;$j++)
	$ResArray[$maIndex[$j]]=$multArray[$maIndex[$j]];
else
for($j=$maSize;$j>=0;$j--)
	$ResArray[$maIndex[$j]]=$multArray[$maIndex[$j]];

return $ResArray;
}
?>
