To pass command line arguments to the script, we simply put them right after the script name like so... Note that the 0th argument is the name of the PHP script that is run. The rest of the array are the values passed in on the command line. The values are accessed via the $argv array.
DESCRIPTION. PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This is the command line interface that enables you to do the following: You can parse and execute files by using parameter -f followed by the name of the file to be executed ...
Introduction. When a PHP script is run from command line, $argv superglobal array contains arguments passed to it. First element in array $argv[0] is always the name of script. This variable is not available if register_argc_argv directive in php. ini is disabled.
From this answer on Server Fault:
Use the php-cgi binary instead of just php, and pass the arguments on the command line, like this:
php-cgi -f index.php left=1058 right=1067 class=A language=English
Which puts this in $_GET:
Array
(
[left] => 1058
[right] => 1067
[class] => A
[language] => English
)
You can also set environment variables that would be set by the web server, like this:
REQUEST_URI='/index.php' SCRIPT_NAME='/index.php' php-cgi -f index.php left=1058 right=1067 class=A language=English
Typically, for passing arguments to a command line script, you will use either the argv global variable or getopt:
// Bash command:
// php -e myscript.php hello
echo $argv[1]; // Prints "hello"
// Bash command:
// php -e myscript.php -f=world
$opts = getopt('f:');
echo $opts['f']; // Prints "world"
$_GET refers to the HTTP GET method parameters, which are unavailable on the command line, since they require a web server to populate.
If you really want to populate $_GET anyway, you can do this:
// Bash command:
// export QUERY_STRING="var=value&arg=value" ; php -e myscript.php
parse_str($_SERVER['QUERY_STRING'], $_GET);
print_r($_GET);
/* Outputs:
Array(
[var] => value
[arg] => value
)
*/
You can also execute a given script, populate $_GET from the command line, without having to modify said script:
export QUERY_STRING="var=value&arg=value" ; \
php -e -r 'parse_str($_SERVER["QUERY_STRING"], $_GET); include "index.php";'
Note that you can do the same with $_POST and $_COOKIE as well.
Sometimes you don't have the option of editing the PHP file to set $_GET to the parameters passed in, and sometimes you can't or don't want to install php-cgi.
I found this to be the best solution for that case:
php -r '$_GET["key"]="value"; require_once("script.php");'
This avoids altering your PHP file and lets you use the plain php command. If you have php-cgi installed, by all means use that, but this is the next best thing. I thought this options was worthy of mention.
The -r means run the PHP code in the string following. You set the $_GET value manually there, and then reference the file you want to run.
It's worth noting you should run this in the right folder, often, but not always, the folder the PHP file is in. 'Requires' statements will use the location of your command to resolve relative URLs, not the location of the file.
I don't have a php-cgi binary on Ubuntu, so I did this:
% alias php-cgi="php -r '"'parse_str(implode("&", array_slice($argv, 2)), $_GET); include($argv[1]);'"' --"
% php-cgi test1.php foo=123
<html>
You set foo to 123.
</html>
%cat test1.php
<html>You set foo to <?php print $_GET['foo']?>.</html>
Use:
php file_name.php var1 var2 varN
Then set your $_GET variables on your first line in PHP, although this is not the desired way of setting a $_GET variable and you may experience problems depending on what you do later with that variable.
if (isset($argv[1])) {
$_GET['variable_name'] = $argv[1];
}
The variables you launch the script with will be accessible from the $argv array in your PHP application. The first entry will the name of the script they came from, so you may want to do an array_shift($argv) to drop that first entry if you want to process a bunch of variables. Or just load into a local variable.
Try using WGET:
WGET 'http://localhost/index.php?a=1&b=2&c=3'
