add up an integer with the result from substr()

[MuffinMan]

Hi,

I'm trying to add up an integer with the result from substr() like

$second_int = substr( .... ) + $int;

I know the result from substr() is an integer and so is $int but in the end
$second_int only has the result from the substr() and hasn't add up the
$int. What am I doing wrong in here... tried quite a few things but well....

Thanks in advance, Maarten

why don't you post what you tried?




$ cat xx.php
<?php
$int = 17;
$text = '01234';

$y = array();
$y[] = substr($text, 1, 2) + $int;
$y[] = substr($text, 1) + $int;
$y[] = substr($text, 1, 55) + $int;
$y[] = substr($text, 1, -2) + $int;
$y[] = substr($text, 1, -22) + $int;
$y[] = substr($text, -3, 2) + $int;
$y[] = substr($text, -3) + $int;
$y[] = substr($text, -3, 55) + $int;
$y[] = substr($text, -3, -2) + $int;
$y[] = substr($text, -3, -22) + $int;

print_r($y);
?>

$ php xx.php
Array
(
[0] => 29
[1] => 1251
[2] => 1251
[3] => 29
[4] => 17
[5] => 40
[6] => 251
[7] => 251
[8] => 19
[9] => 17
)

$second_int = intval(substr( .... )) + $int;
should work imho.

Well, you're right nothing wrong in it but vars were defined outside a
function which gave a problem... next problem.... next thread..

You didn't make them global now, did you? :-)
