intval - Get the integer value of a variable

SYNOPSIS
int intval (mixed $var, [int $base = 10]) DESCRIPTION
Returns the integer value of $var, using the specified $base for the conversion (the default is base 10). intval(3) should not be used on objects, as doing so will emit an E_NOTICE level error and return 1. PARAMETERS
o $var - The scalar value being converted to an integer o $base - The base for the conversion Note If $base is 0, the base used is determined by the format of $var: o if string includes a "0x" (or "0X") prefix, the base is taken as 16 (hex); otherwise, o if string starts with "0", the base is taken as 8 (octal); otherwise, o the base is taken as 10 (decimal). RETURN VALUES
The integer value of $var on success, or 0 on failure. Empty arrays return 0, non-empty arrays return 1. The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example on such a system, intval('1000000000000') will return 2147483647. The maximum signed integer value for 64 bit systems is 9223372036854775807. Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of integer casting apply. EXAMPLES
Example #1 intval(3) examples The following examples are based on a 32 bit system. <?php echo intval(42); // 42 echo intval(4.2); // 4 echo intval('42'); // 42 echo intval('+42'); // 42 echo intval('-42'); // -42 echo intval(042); // 34 echo intval('042'); // 42 echo intval(1e10); // 1410065408 echo intval('1e10'); // 1 echo intval(0x1A); // 26 echo intval(42000000); // 42000000 echo intval(420000000000000000000); // 0 echo intval('420000000000000000000'); // 2147483647 echo intval(42, 8); // 42 echo intval('42', 8); // 34 echo intval(array()); // 0 echo intval(array('foo', 'bar')); // 1 ?> NOTES
Note The $base parameter has no effect unless the $var parameter is a string. CHANGELOG
