crc32
(PHP 4 >= 4.0.1, PHP 5)
crc32 — Calculates the crc32 polynomial of a string
Description
int crc32
( string $str
)
Because PHP's integer type is signed, and many crc32 checksums will
result in negative integers, you need to use the "%u" formatter of
sprintf() or printf() to get
the string representation of the unsigned crc32 checksum.
Return Values
Returns the crc32 checksum of str
as an integer.
Examples
Example #1 Displaying a crc32 checksum
This example shows how to print a converted checksum with the
printf() function:
<?php
$checksum = crc32("The quick brown fox jumped over the lazy dog.");
printf("%u\n", $checksum);
?>
