[SOLVED] PHP string to number

[woody79]

this is a string:    $number = "9";

this is a number: $number = 9;

I need to get a string into a number because i am grabbing the number using the GET funtion

[redarrow]

so add a varable to the get.

 

<?php

$number=$_GET['the_number'];

echo $number;

?>

 

 

$number holds 9

[chigley]

<?php

$number = "9";

$number = intval($number); // $number = 9;

?>

[woody79]

Okay,

<?php

$number = "9";

$number = intval($number); // $number = 9;

?>

that didn't work and i tried intval like this

$number = intval($_GET['myNumber']);
echo $number;
$number++;

$number did not increment

thats because you incremented number after oyu echoed it

You might be able to do this as well:

 

$number = (int)$_GET['myNumber'];

$number++;

echo $number;

i think there is a difference in what is an int and whats a string in php 4/5

[JustinK101]

I think it works either way. I just tested incrementing a string with 12 in it, and it worked.
