I`d like to make a note on this post:
/*-------------------------------------*/
<?php
echo crc32('example')+4294967296;
?>
gives you the same result as the CRC32() function in MySQL (>=4.1)
"SELECT CRC32('example')" .......
/*-------------------------------------*/
This is actually wrong and works just for some strings, do not use this.
crc32() php and mysql functions both return the same results.
Use php sprintf() or printf() rather than echo() and read manual carefully.
