Need to store numbers in the array

[Nightcat]

OK
I am importing a CSV file which holds 3 sets of data.

2 of the sets holding numbers for use as coordinates in JGraph.

When I am supplying these numbers into arrays they are stored as strings and I need them to be stored as integers.

I tried using settype(),but to no avail

any ideas?

foreach ($file_content as $line){
        
        $values=explode(',', $line);
        $x_axis=$values[1];
        $y_axis=$values[2];
        settype($x_axis, 'int');
        settype($y_axis, 'int');
        array_push($_SESSION['names'], $values[0]);
        array_push($_SESSION['x_axis'], $x_axis);
        array_push($_SESSION['y_axis'], $y_axis);
        
    }

Do you know what version of PHP you are running? Apparently before 4.2.0 you had to user 'integer' instead of 'int'?

It normally should not matter, as PHP is a "loosely typed" language and will convert types automatically when required, at least in the vast majority of cases. But if you really need to cast it to an integer, the simplest way is:

$x_axis= (int) $values[1];

I am running PHP 5

I'll try NogDogs advice, though it's prety bad for me to forget about it
