how to have 64 bit integer on PHP?

Is it possible to use a 64-bit Long integer as a key in Cassandra using PHPCassa?

For example,

$pool = new ConnectionPool('main', array("127.0.0.1")); 
$table = new ColumnFamily($pool, 'messages'); // ColumnFamily 
$table->insert("5601379860409749867", array("sampleKey" => "sampleValue));

Every time that I do the insert, I get 0 for the key. In this table, the key_validation_class is LongType.

If your PHP is a 32 bits version, I think you just can't. Switch to 64 bits system or wait for a PHP way-to-fix (might be longer ^^) — shkschneider, Jul 29 '12 at 19:06

This is totally dependant on your server's operating system capabilities, and not a limitation of PHPCassa.

Native 64-bit integers require 64-bit hardware AND the 64-bit version of PHP.

On 32-bit hardware:

$ php -r 'echo PHP_INT_MAX;'
2147483647

On 64-bit hardware:

$ php -r 'echo PHP_INT_MAX;'
