Question

how to send array through url in PHP?

I have an array of product ids i want to use these id through url because this is the osCommerce needs it in which i am working

Answer 1

well what i would do is json_encode(php json) the array and assign that to a variable in php. you can then urlencode the variable to send it via the url. On the other end you can json_decode. Do look up for json if you are not aware of it. its very powerful and useful though.

Answer 2

?arr[]=abc&arr[]=pqr&arr[]=xyz&arr[]=xxx

Answer 3

Your looking for http_build_query().

Example from php.net:

$data = array('foo'=>'bar',
              'baz'=>'boom',
              'cow'=>'milk',
              'php'=>'hypertext processor');

echo http_build_query($data);
// foo=bar&baz=boom&cow=milk&php=hypertext+processor

echo http_build_query($data, '', '&');
// foo=bar&baz=boom&cow=milk&php=hypertext+processor

Answer 4

It should be sufficient to encode them like this:

http://your.url/page.php?myArray[0]=val1&myArray[1]=val2

Answer 5

If you are POST-ing data, then name your fields with PHP array-style syntax:

<input type="text" name="myArray[]" value="A">
<input type="text" name="myArray[]" value="B">
<input type="text" name="myArray[]" value="C">

If you want to pass the data in a GET request, you can separate the data and split it server side using explode:

page.php?myData=A,B,C,D

...

$myArray = explode(',', $_POST['myData']);

Answer 6

If you already have the product IDs in an array, then you can use the http_build_query() function, which will encode the array like thus:

http://www.example.com/?pid[]=1&pid[]=2&pid[]=3 ...

Hope that helps.
