Description
resource
gmp_init ( mixed number [, int base] )
Creates a GMP number from an integer or string. String
representation can be decimal, hexadecimal or octal.
Optional parameter base is available since
PHP 4.1.0. Its default value is 0.
The base may vary from 2 to 36. If base is 0 (default value), the
actual base is determined from the leading characters: if the first
two characters are 0x or 0X,
hexadecimal is assumed, otherwise if the first character is "0",
octal is assumed, otherwise decimal is assumed.
Example 1. Creating GMP number
<?php
$a = gmp_init(123456);
$b = gmp_init("0xFFFFDEBACDFEDF7200");
?>

Note:
It is not necessary to call this function if you want to use
integer or string in place of GMP number in GMP functions, like
gmp_add(). Function arguments are
automatically converted to GMP numbers, if such conversion is
possible and needed, using the same rules as
gmp_init().
