如何通过参数将多字符串变量传递给php

Question

How do I send in a "multi"-string variable(looking like this: 1,2.3,4) into a php through a parameter which goes through an url.

Lets say some of the php that is connected to the mysql server looks something like this

`$id_ = $_GET['id'];`
`$q=mysql_query("SELECT * FROM brain WHERE braincell_id in ('$id_');`

And the variable that goes into it is: id = 1,2,3,4

How can I make this work?

What I am using currently and that does work:

$q=mysql_query("SELECT * FROM brain WHERE braincell_id in ("$_GET['id']");

EDIT. Sorry it's me being stupid, it is way to late for me to be doing this stuff..... I missed a parentheses please remove this post.

Answer 1

Pass $q , your result resource. It references all the data returned from MySQL, and you can use the usual mysql_* functions on it (eg. mysql_fetch_array() ).

Alternatively, call mysql_fetch_array() (or similar) and pass the resultant array to your function.

Answer 2

The only solution that I know that will work out of the box is to pass each element of array as an separate parameter.

Here is my example:

get.php:

    $arr = $_GET['id'];

    echo '<ul>';
    foreach($arr as $id)
    {
        echo "<li>{$id}</li>";
    }
    echo '</ul>';

URL:

get.php?id[]=1&id[]=2&id[]=3

Also you can pass key for each element:

get.php?id[0]=1&id[1]=2&id[2]=3
