PHP: array that only contains matching items from larger array

Using PHP, how can I get an array that only contains matching items from a larger array?
<?php

$oRSList = array();
$oRSList[] = array('Name'=>'Apple','NumericID'=>'63');
$oRSList[] = array('Name'=>'Peach','NumericID'=>'237');
$oRSList[] = array('Name'=>'Grape','NumericID'=>'163');
$oRSList[] = array('Name'=>'Prune','NumericID'=>'168');
$oRSList[] = array('Name'=>'Mango','NumericID'=>'639');

print_r($oRSList);
?>

Open in new window


I want my new array to only contain items with a NumericID that contains '63'.

These three items contain '63' in their NumericID:
$oRSList[] = array('Name'=>'Apple','NumericID'=>'63');
$oRSList[] = array('Name'=>'Grape','NumericID'=>'163');
$oRSList[] = array('Name'=>'Mango','NumericID'=>'639');

because those items contain '63' in the NumericID.

Try with this
<?php

$oRSList = array();
$oRSList[] = array('Name'=>'Apple','NumericID'=>'63');
$oRSList[] = array('Name'=>'Peach','NumericID'=>'237');
$oRSList[] = array('Name'=>'Grape','NumericID'=>'163');
$oRSList[] = array('Name'=>'Prune','NumericID'=>'168');
$oRSList[] = array('Name'=>'Mango','NumericID'=>'639');

print_r($oRSList);

$arr63 = array();

foreach ($oRSList as $person) {
	if (strpos($person['NumericID'], '63') !== false)
	{
    $arr63[] = $person['Name'];
	}
}
print_r($arr63);
?>

Try this ;)

Let suppose your array with all values is: $oRSList then to check value NumericID we need to iterate this array

$itemsWith63 = array();
foreach($oRSList as $item){
    if(strpos('63', $item['NumericID']) !== false){
        $itemsWith63[] = $item; 
    }
}

array_filter()
<?php
$oRSList = array();
$oRSList[] = array('Name'=>'Apple','NumericID'=>'63');
$oRSList[] = array('Name'=>'Peach','NumericID'=>'237');
$oRSList[] = array('Name'=>'Grape','NumericID'=>'163');
$oRSList[] = array('Name'=>'Prune','NumericID'=>'168');
$oRSList[] = array('Name'=>'Mango','NumericID'=>'639');

$result = array_filter($oRSList, function($var) {
  return (strpos($var['NumericID'], '63') !== false);
});
echo "<pre>" . print_r($result, true) . "</pre>";
