PHP passing $_GET in the Linux command prompt_问答_开发者

Say we usually it access via

http://localhost/index.php?a=1&b=2&c=3

How do we execute the same on a Linux command prompt?

php -e in开发者_如何转开发dex.php

But what about passing the $_GET variables? Maybe something like php -e index.php --a 1 --b 2 --c 3? I doubt that'll work.

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'

Option 1: php-cgi

Use 'php-cgi' in place of 'php' to run your script. This is the simplest way as you won't need to specially modify your PHP code to work with it:

php-cgi -f /my/script/file.php a=1 b=2 c=3

Option 2: If you have a web server

If the PHP file is on a web server you can use 'wget' on the command line:

wget 'http://localhost/my/script/file.php?a=1&b=2&c=3'

Or:

wget -q -O - "http://localhost/my/script/file.php?a=1&b=2&c=3"

Accessing the variables in PHP

In both option 1 & 2, you access these parameters like this:

$a = $_GET["a"];
$b = $_GET["b"];
$c = $_GET["c"];

If you have the possibility to edit the PHP script, you can artificially populate the $_GET array using the following code at the beginning of the script and then call the script with the syntax: php -f script.php name1=value1 name2=value2

// When invoking the script via CLI like 
// "php -f script.php name1=value1 name2=value2", 
// this code will populate $_GET variables called 
// "name1" and "name2", so a script designed to 
// be called by a web server will work even 
// when called by CLI
if (php_sapi_name() == "cli") {
    for ($c = 1; $c < $argc; $c++) {
        $param = explode("=", $argv[$c], 2);
        $_GET[$param[0]] = $param[1]; // $_GET['name1'] = 'value1'
    }
}

If you need to pass $_GET, $_REQUEST, $_POST, or anything else you can also use PHP interactive mode:

php -a

Then type:

<?php
    $_GET['a'] = 1;
    $_POST['b'] = 2;
    include("/somefolder/some_file_path.php");

This will manually set any variables you want and then run your PHP file with those variables set.

At the command line, paste the following:

export QUERY_STRING="param1=abc&param2=xyz" ;  
POST_STRING="name=John&lastname=Doe" ; php -e -r 
'parse_str($_SERVER["QUERY_STRING"], $_GET); parse_str($_SERVER["POST_STRING"], 
$_POST);  include "index.php";'

I just pass them like this:

php5 script.php param1=blabla param2=yadayada

It works just fine. The $_GET array is:

array(3) {
  ["script_php"]=>
  string(0) ""
  ["param1"]=>
  string(6) "blabla"
  ["param2"]=>
  string(8) "yadayada"
}

Use:

php -r 'parse_str($argv[2],$_GET);include $argv[1];' index.php 'a=1&b=2'

You could make the first part as an alias:

alias php-get='php -r '\''parse_str($argv[2],$_GET);include $argv[1];'\'

Then simply use:

php-get some_script.php 'a=1&b=2&c=3'

Or just (if you have Lynx):

lynx 'http://localhost/index.php?a=1&b=2&c=3'
