$argv[] - Command Line Arguments
This section provides a tutorial example on how to use the built-in array, $argv[], to retrieve command line arguments when PHP script files are executed with the 'php' command.
If a PHP script file is executed through the "php" command, additional command line arguments can be passed to the script through the built-in array: $argv.
For example, if "php test.php arg1 arg2 ..." is used to execute the script file called test.php, the built-in array, $argv, will be populated the following values:
$argv[0]: test.php $argv[1]: arg1 $argv[2]: arg2 $argv[.]: ...
Here is an example PHP script that echoes it's command line arguments:
herong$ more command-line-arguments.php <?php for ($i=0; $i<count($argv); $i++) { echo "\$argv[$i] = $argv[$i]\n"; } ?> herong$ php command-line-arguments.php arg1 arg2 arg3 $argv[0] = command-line-arguments.php $argv[1] = arg1 $argv[2] = arg2 $argv[3] = arg3 herong$ php command-line-arguments.php "arg1 arg2" arg3 $argv[0] = command-line-arguments.php $argv[1] = arg1 arg2 $argv[2] = arg3
Note that how quotes are used to protect space character as part of a single argument.
