You should have a look at the Type Juggling manual page:
http://www.php.net/manual/en/language.types.type-juggling.php


<?php
header('Content-Type: text/plain');
error_reporting(E_ALL);
ini_set('display_errors', '1');

$x1 = '0';
$x2 = 'xs';
$x3 = 0;

$tests = array();
$tests[] = 'return $x1 == $x2;';
$tests[] = 'return $x1 === $x2;';
$tests[] = 'return $x1 == $x3;';
$tests[] = 'return $x1 === $x3;';
$tests[] = 'return $x2 == $x3;';
$tests[] = 'return $x2 === $x3;';
$tests[] = 'return $x1 == 0;';
$tests[] = 'return $x1 === 0;';
$tests[] = 'return $x1 == \'0\';';
$tests[] = 'return $x1 === \'0\';';
$tests[] = 'return $x2 == 0;';
$tests[] = 'return $x2 === 0;';
$tests[] = 'return $x2 == \'0\';';
$tests[] = 'return $x2 === \'0\';';
$tests[] = 'return $x3 == 0;';
$tests[] = 'return $x3 === 0;';
$tests[] = 'return $x3 == \'0\';';
$tests[] = 'return $x3 === \'0\';';

echo '$x1 = \'0\';
$x2 = \'xs\';
$x3 = 0;

';
$n = 0;
foreach ($tests as $v) {
echo $v, "\treturns ", (eval($v)) ? ('true') : ('false'), "\n";
}
?>
