Can't get string numbers to become float or integer PHP - php

Question

I'm trying to parse a csv file with PHP and everything works ok as long as I keep the numbers as strings. However, since I'd like to sum the values of nested arrays I need them to be numbers.
There are three values that I need to fix:
$column[1] is cost and contains decimals (ex. 20.30)
$column[2] is clicks (ex. 15)
$column[3] is conversions (ex. 3)
If I try using floatval() or intval() on the values they return 0.
Example: $cost = intval($column[1]);
I saw somewhere in another thread that they use trim() or ltrim() to clean up the value. So I tried that on my numbers...
$cost = intval(trim($column[1]));
$clicks = intval(trim($column[2]));
$conversions = intval(trim($column[3]));
But that just gives me the first digit of the number, so I get this..
cost : 2 (instead of 20.30)
clicks : 1 (instead of 15)
conversions: 3 (is actually correct)
I've tried using both "." and "," as decimals.
Really can't figure this one out. Any help I can get is much appreciated!
Structure:

[0]=> string(21)"avslag l�n"[1]=> string(11)"31.32"[2]=> string(3)"1"[3]=> string(5)"0 "
}
array(4) {
[0]=> string(45)"l�na trots kronofogden"[1]=> string(11)"99.12"[2]=> string(3)"2"[3]=> string(5)"0 "
}
array(4) {
[0]=> string(59)"g�r gymnasiet men vill ta l�n"[1]=> string(11)"33.86"[2]=> string(3)"1"[3]=> string(5)"0 "
}
array(4) {
[0]=> string(45)"l�n till enskild firma"[1]=> string(11)"80.07"[2]=> string(3)"1"[3]=> string(5)"1 "
}

Answer 1

You could type cast the values as follows:
$cost = (double) $column[1];
$clicks = (int) $column[2];
$conversions = (int) $column[3];
http://www.php.net/manual/en/language.types.type-juggling.php
if you are looking to format the double then do the following:
$cost = number_format($column[1], 2);
EDIT: Thanks for the var_dump, try this.
$cost = (double) $column[0][1];
$clicks = (int) $column[0][2];
$conversions = (int) $column[0][3];
You are trying to interact with a 2D array as if it was 1 dimensional.

Answer 2

use number format with floatval
$cost = floatval(column[1]);
$cost = number_format($cost, 2);

Answer 3

if value of $column[1] is "20.30" you can simply use it for calculations as php automatically converts string to numbers when you do arthritic calculations.
ex:
$column[1]="20.30";//$column[1] is string.
$column[1]*=1.0;//Now $column[1] is an float variable..
You can also use type conversion like:
$a=(float)$column[1]*1;
And so on..

Answer 4

I could be wrong...in which case I have a gambling problem apparently...but I'm fairly certain you're trying to do all these conversions on an actual array(), not a string.
Your printout shows 4 different arrays, each with key/value pairs. And all of these are linked into $column.
If I had to guess, which I shouldn't do on Stack Exchange, I would say try this:
$column[1][1]
instead of what you have now as
$column[1]
I've been up quite a long time though so grain of salts are to be taken here.
