Maybe this example can help you:

foreach($myArrayOfObject as $key=>$object) {
    if($object->aPropertyOfMyObject) {
        // do something...
    }
}

You can also have a look to http://php.net/manual/en/control-structures.foreach.php

Do you specifically need foreach?

You can also use this:

<?php

$array = array(); // Imagine a filled array
array $max = count($array);

for($i=0;$i<$max;$i++) {
 // Loop over the array
 echo $array[$i]['name_of_key']; 
}

?>
