Alright, so I've been toying around with the Steam Web API, I have one of the values stored in a variable called $steam64. When I use this code snipper to INSERT it into a mysql database it insert a completley different integer than what is stored in the variable.
$sql_query = "INSERT INTO users_info (steam64) VALUES ('$steam64')";
var_dump($steam64); returns the real int, so does echoing it. Not too sure what is going on here, any help is appreciated.
Based on your comment of "value being dumped"; the number you are trying to insert is too large for 32-bit systems. The max for 32-bit is 4,294,967,295, and the max for 64-bit is 18,446,744,073,709,551,615. I'd recommend converting your column into a varchar(100) hash rather than an int, or switch to a 64 bit system. Great article about max ints here, and here.
Also, before I get flamed, be sure to read up on SQL injection in case you are not sanitizing variables being posted directly into sql statements.
