When use an huge array, it's recommended to set a variable with the size of the array, p.g.
<?php
$array_size = count($your_array);
for($i = 0; $i < $array_size; $i++)
{
// Process array data
}
?>
It's quicker than:
<?php
for($i = 0; $i < sizeof($your_array); $i++)
{
// Process array data
}
?>
In the first example, run the sizeof function once, however in the second example run n times the
sizeof function
