I'm curious if I can assign a variable the value of a specific array index value returned by a function in PHP on one line.
Right now I have a function that returns an associative array and I do what I want in two lines.
$var = myFunction($param1, $param2);
$var = $var['specificIndex'];
without adding a parameter that determines what the return type is, is there a way to do this in one line?
In PHP 5.4, you can do this: $var = myFunction(param1, param2)['specificIndex'];.
Another option is to know the order of the array, and use list(). Note that list only works with numeric arrays.
For example:
function myFunction($a, $b){
// CODE
return array(12, 16);
}
list(,$b) = myFunction(1,2); // $b is now 16
list(,$b) is probably not the best syntax to use for readability, though (in my opinion).
You could add an additional optional parameter and, if set, would return that value. See the following code:
function myFunction($param1, $param2, $returnVal = "")
{
$arr = array();
// your code here
if ($returnVal)
{
return $arr[$returnval];
}
else
{
return $arr;
}
}
return ( $returnVal) ? $arr[$returnVal] : $arr;if statement.
