intval
INTVAL(3) 1 INTVAL(3)intval - Get the integer value of a variableSYNOPSIS
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.
