.Net int() equivalent in PHP

Question

I'm converting a .net app to php. What would be the php equivalent of int(6.22555445656) in php?

Answer 1

This should clear it up:

<?php
header("Content-Type: text/plain");
$arr = array(-6, -6.2, -6.7, 5, 5.3, 5.8);
foreach ($arr as $v) {
  printf("%f: (int) = %d, floor = %d, ceil = %d\n", $v, (int)$v, floor($v), ceil($v));
}
?>

outputs:

-6.000000: (int) = -6, floor = -6, ceil = -6
-6.200000: (int) = -6, floor = -7, ceil = -6
-6.700000: (int) = -6, floor = -7, ceil = -6
5.000000: (int) = 5, floor = 5, ceil = 5
5.300000: (int) = 5, floor = 5, ceil = 6
5.800000: (int) = 5, floor = 5, ceil = 6

Note: Casting to int and floor() do different things.

Edit: Oh, you want to convert from a string to an int. One piece of advice: when you ask questions like these, describe what the original function does. You'll get a quicker and clearer answer.

Also, bear in mind that types in PHP and .Net work different. For example:

$foo = '-234'; // string
$bar = $foo + 5;
print $bar; // -229

PHP has a complex type juggling system to automatically convert the type of variables as required. This includes going to and from booleans, integers, floats and strings as required.

I'm not certain what your goal is. But you can try

$var = (int) 6.22555445656;
print $var; // 6

Also see intval()
