converting array contents to http query

Question

I have array like this one.

$fields = array(
            'user[facebook_gender]' => urlencode("female"),
            'user[facebook_likes]' => array(1,2,3,4,5,6)
);

foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
$fields_string=rtrim($fields_string, '&');

then I get

user[facebook_gender]=female&user[facebook_likes]=Array

It just show "Array", however I want to show the content of Array,

What is your question? How to turn an array into a string? How to create a url from an array? — Brett Santore

Have a look at the serialize function

http://php.net/manual/en/function.serialize.php

For example:

foreach($fields as $key=>$value) {
  if (is_array($value)) $value = serialize($value);
  $fields_string .= $key.'='.$value.'&';
}
$fields_string=rtrim($fields_string, '&');

Note that you have to use unserialize() on your target site, to make use of the value again.

Actually, http_build_query does exactly what you need.

Use implode on the array:

foreach($fields as $key=>$value) {
    if(is_array($value))
    {
         $value = implode($value,",");
    }
    $fields_string .= $key.'='.$value.'&';
}
$fields_string=rtrim($fields_string, '&');
