Converting associative array into string of "id = value, id = value" in one line in PHP

Question

In Python I would do something like this heaving the following dictionary (equiv of php's assoc array).

arr = {'id': '1', 'name': 'marcin', 'born': '1981-10-23'}
print ', '.join([('`%s` = "%s"') % (k,v) for k,v in arr.items()])

to get:

`born` = "1981-10-23", `id` = "1", `name` = "marcin"

Assuming PHP array is:

array("id"=>"1","name"=>"marcin","born"=>"1981-10-23");

Is there a way of getting the same result in PHP 5.3 without using foreach loop?

Answer 1

Check out the relatively new http_build_query function:

• http://php.net/manual/en/function.http-build-query.php

E.g.

echo http_build_query(array('foo'=>'bar', 'zig'=>'zag', 'tic'=>'tac'), '', ', ');

outputs:

foo=bar, zig=zag, tic=tac

It's intended for making query strings, but the 3rd argument arg_separator can be any string (default "&").

(This doesn't address your quoting concerns, but it may still be helpful)
