return array(1) ?

[runrunforest]

Hi,

Any idea what the array(1) means ?

[SoulScratch]

<Facedown> !php function foo(){return array(1);}; $res = foo(); echo $res[0];
<WhiteVal> Return: 1

It should most likely be array[1] unless array is the name of a function, in which case it is poorly named.

Arrays have keys. For an indexed array they are siquential starting at zero

$sports = array('Football', 'Squash', 'Swimming', 'Pole Hurling');
echo $sports[1];  //Squash 

So $array[1] is the second element in an array.

array(1) would be calling a function called array, and passing the value of 1 as an argument.

array() is the built in function for creating an array so

return array(1)

will create a new array containing a single element with a value of 1 and will then return that array. Presumably there are other return statements within the function that return arrays containing other values.

Far out, I can't believe it didn't occur to me that the built in function is probably what was intended. Whoops.
