Is it possible to pass an array as a command line argument to a PHP script?

Question

I\'m maintaining a PHP library that is responsible for fetching and storing incoming data (POST, GET, command line arguments, etc). I\'ve just fixed a bug that would not all

Answer 1

Sort of.

If you pass something like this:

$php script.php --opt1={'element1':'value1','element2':'value2'}

You get this in the opt1 argument:

Array(
 [0] => 'element1:value1'
 [1] => 'element2:value2'
)

so you can convert that using this snippet:

foreach($opt1 as $element){
    $element = explode(':', $element);
    $real_opt1[$element[0]] = $element[1];
}

which turns it into this:

Array(
 [element1] => 'value1'
 [element2] => 'value2'
)

Answer 2

Directly not, all arguments passed in command line are strings, but you can use query string as one argument to pass all variables with their names:

php myscript.php a[]=1&a[]=2.2&a[b]=c

<?php
parse_str($argv[1]);
var_dump($a);
?>

/*
array(3) {
  [0]=> string(1) "1"
  [1]=> string(3) "2.2"
  ["b"]=>string(1) "c"
}
*/

Answer 3

The following code block will do it passing the array as a set of comma separated values:

<?php
  $i_array = explode(',',$argv[1]);
  var_dump($i_array);
?>

OUTPUT:

php ./array_play.php 1,2,3

array(3) {
  [0]=>
  string(1) "1"
  [1]=>
  string(1) "2"
  [2]=>
  string(1) "3"
}
