Shell run/execute php script with parameters

Posted by: admin November 29, 2017 Leave a comment

Questions:

I need to execute a php file with parameters through shell.

here is how I would run the php file:

php -q htdocs/file.php

I need to have the parameter ‘show’ be passed through and

php -q htdocs/file.php?show=show_name

doesn’t work

If someone could spell out to me what command to execute to get the php file to execute with set parameters, it would be much appreciated. If not, try to lead me the right direction.

Answers:

test.php:

<?php
print_r($argv);
?>

Shell:

$ php -q test.php foo bar
Array
(
    [0] => test.php
    [1] => foo
    [2] => bar
)

If you have webserver (not only just php interpreter installed, but LAMP/LNMP/etc) – just try this

wget -O - -q -t 1 "http://mysite.com/file.php?show=show_name" >/dev/null 2>&1

where:

  • « -O – » — (Letter “O”, not zero!) redirect “downloaded html” to stdout
  • « >/dev/null 2>&1 » — redirect stdout & stderr output to nowhere
  • « -q » — quiet wget run
  • « -t 1 » — just 1 try to connect (not like default 20)

In PHP’s “exec” it’ll be smth like this:

function exec_local_url($url) {
  exec('/usr/bin/wget -O - -q -t 1 "http://'. $_SERVER['HTTP_HOST'] .'/'
    . addslashes($url) . '" >/dev/null 2>&1'
  );
}

// ...

exec_local_url("file.php?show=show_name");
exec_local_url("myframework/seo-readable/show/show_name");

So, you don’t need to change your scripts to handle argc/argv, and may use $_GET as usually do.

If you want jobs runned in background – see for ex. Unix/Windows, Setup background process? from php code

I use approach with wget in my cron jobs; hope it helps.

You need to read command line parameters from $argc and $argv.

Using a question mark is something you do in a URL and has nothing to do with executing PHP from a command line.

In addition to the other answers (Which are quite correct), you can also pass arguments as environment parameters, like this:

FOO=42 BAR=quux php test.php

They will then be available in the superglobal $_ENV.

If you are using it from a PHP file then you can use popen() and do something like this:

$part = $show_name; //or whatever you want with spaces

$handle = popen("php -q nah.php -p=". escapeshellarg($part) . " 2>&1", "r");

This uses the escapeshellarg() function in order to wrap the $part variable in quotes (and escape any quotes inside it), so that it can be used as a shell argument safely.
