Question

I am trying to pass on an array from a function on one sheet into a new array on another php sheet.

Here’s what i have:

The function is:

//the arr.php file

<?php

function search($var){
$var;

$a=array();
$a[0]=$var+1;
$a[1]=$var+2;
$a[2]=$var+3;
$a[3]=$var+4;
return $a;
}
?>

The second sheet is:

<?php

include ('arr.php');
$n=4;

for($i=0;$i<$n;$i++)
{

$temp=search(3); 

$thearrayfromarr[$i]=$temp;//doesn't work
print_r($thearrayfromarr[$i]);//doesn't work
}

?>

I want the second sheet to have an array variable which i can echo that will output
the $a array data from the search function.

So that, for example, when i type

echo thearrayfromarr[0]; // It will have the value of $a[0] echo'd to me

Your function isn’t returning anything:

function search($var) {
    $a=array();
    $a[0]=$var+1;
    $a[1]=$var+2;
    $a[2]=$var+3;
    $a[3]=$var+4;
    return $a; // Need this
}
