Yes you can do it like that but you should reference the arguments from the $_SERVER['argv']
array. $_SERVER['argc']
will tell you how many args were received, should you want to use that as a first layer of validation to make sure a required number of args were input.
To illustrate this, running the following script as args.php arg1 arg2 arg3
:
#!/usr/bin/php
<?php
var_dump($argv);
?>
will output:
array(4) {
[0]=>
string(8) "args.php"
[1]=>
string(4) "arg1"
[2]=>
string(4) "arg2"
[3]=>
string(4) "arg3"
}
Here is a practical example:
In this example, we'll create a script (days.php) that outputs the number of days since a particular date. It will accept 3 parameters, the month, day, and year as numbers.
#!/usr/bin/php
<?php
if($argc < 4 || !is_numeric($argv[1]) || !is_numeric($argv[2]) || !is_numeric($argv[3]))
{
echo "Usage: $argv[0] mm dd yyyy
";
}
else
{
$pastdate = mktime(0, 0, 0, $argv[1], $argv[2], $argv[3]);
$diff = time() - $pastdate;
$days = round($diff/60/60/24);
echo "$days days since $argv[1]/$argv[2]/$argv[3]
";
}
?>
Shell call:
`$ ./days 11 17 1988` OR `php days.php 11 17 1988`
Output:
7699 days since 11/17/1988
Hope this helps.
