Function Param=Null Array Foreach Check For Param

[quasiman]

Hi, Nice new forum!

 

I'm writing a function that combines two arrays, and based on the params assigned returns a new array. The problem I'm having is making one of the parameters not required. This would return all results not filtered by the param, or if included would only return the filtered results. Here's where I am so far...

<?php
function showPlan($type, $cat, $name=null) {
$planDetails = getData('products/plan-details');
$customerPrice = getData('products/customer-price');
$a1 = $planDetails[$type];
$a2 = $customerPrice[$type];
$a3 = combineArray($a1, $a2); //external function combining the two above arrays
$array = array();
foreach ($a3 as $keys) {
 if ($keys[0]['category'] == $cat) {
	 if(isset($name) && $keys[0]['plan_name'] == $name) {
		 foreach ($keys[0] as $key => $value) {
			 $array[$key] = $value;
		 }
		 foreach ($keys[1]['add'] as $key => $value) {
			 $array[$key] = $value;
		 }
	 }
 }
}
return $array;
}
?>

 

Now, if I take out the line "if(isset($name) && $keys[0]['plan_name'] == $name)" and force the $name param, this function works fine. But I don't want to write two functions simply to return all results or only one result.

 

Any help would be greatly appreciated!

So include the result if there's a $name and it matches, or include the result if there was no $name given?

if ((name is given AND it matches) OR (name is not given))

Well now I feel dumb. LOL! Thanks.....

i am not that good still learning though but in my own opinion i think you have mixed things here. the better way to check i think would be to do a var_dump($a3) because it seems to me that this

if(isset($name) && $keys[0]['plan_name'] == $name) {

evaluate to false
