Question

I have this function below:

public function set_partial($array)
{
    if (is_array($array)) {
        foreach ($array as $each) {
            self::$_partials[$each[0]] = array('view' => $each[1], 'data' => $each[2]);
        }
    }
}

In self::$_partials, ‘data’ isn’t required. So how do I keep my code simple while allowing data to be null? Right now, if data isn’t provided, then I get an offset error.

You can check to see if each[2] isset. If it is, then set the variable, otherwise make it null:

<?php
public function set_partial($array){
    if(is_array($array)){
        foreach ($array as $each) {
            self::$_partials[$each[0]] = array('view' => $each[1], 'data' => (isset($each[2])?$each[2]:NULL));
        }
    }
