====== command line php ======
See the current options with php --help.  If you want to run a file from the command line instead of through the browser, simply do this:<code>
php <filename>
</code>

===== running without a file =====
The -r flag tells php to not require code tags, and allows code to be used instead of a file name.
<code>
php -r 'echo date("Y-m-d h:i:s", strtotime("2004-10-28T16:37:15Z")) . "\n";'
</code>

===== interactive mode =====
PHP allows you to have commands executed as you type them.  To start in interactive mode, use the -a switch.
<code php>
$ php -a
Interactive mode enabled

<?
ob_start();
$now = time();
echo date("Y-m-d", $now);
exit("\n");
</code>
(output will be the current date)
