Explode Nightmare

[otonix]

I am having a nightmare with an explode and cant get it to work. I am posting a string using JQuery to a PHP form which needs to explode the string into an indexed array to be inserted into a database.

 

This is what the string looks like "importance%5B101%5D=50&importance%5B100%5D=50&importance%5B99%5D=50&importance%5B98%5D=50"

 

The original array has been serialised into the above string. The arrayname is importance. The array's index (inside the square brackets) is referenced from an ID from the page.  The square brackets have been replaced by '%5B' and '%5D' and surround the array index by the JQuery. The value for each of these array items is shown as =50. So its basically the same as a GET when we have name=value&name1=value1etc')

 

How would i explode the string above to remove the '%5B' and '%5D' to make the '[' and ']' reappear and then from then it can be read as a GET post? like 'name=value&name1=value1etc'. Using the new array of that index ready to be inserted into a MySQL database.

 

Im going mad trying to solve this!!!

Have you tried urldecode()?

This will convert the string into an array (or arrays) based on the name(s) used in the string. In this case it would be an array variable $importance

$encodedString = "importance%5B101%5D=50&importance%5B100%5D=50&importance%5B99%5D=50&importance%5B98%5D=50";

$decodedString = urldecode($encodedString);
$explodedVars = explode('&', $decodedString);
foreach($explodedVars as $nameValuePair)
{
    preg_match("#(.*)\[([^\]]*)\]=(.*)#", $nameValuePair, $matches);
    ${$matches[1]}[$matches[2]] = $matches[3];
}

print_r($importance);

/*Output---
Array
(
    [101] => 50
    [100] => 50
    [99] => 50
    [98] => 50
)
*/

Or to get an array, simply this:

 

$s = "importance%5B101%5D=50&importance%5B100%5D=50&importance%5B99%5D=50&importance%5B98%5D=50";

parse_str(urldecode($s), $array);

print_r($array);

parse_str(urldecode($s), $array);

print_r($array);

 

Damn it! I was thinking there should be a function to do that.
