I have been Googling for hours but I can't make heads nor tails out of it. I have a multidimensional associative array like this:
$mArray = array(
array("m" => "0"),
array("m" => "1"),
array("m" => "1")
);
I would like to create the array with PHP GET request:
mywebsite.com/file.php?.......what do I put here?.....
You need to use array access notation like this
mywebsite.com/file.php?item[0][m]=0&item[1][m]=1&item[2][m]=1
It would be simple to use nested loops to build this string - don't forget to URL encode the values
$query_string = '';
foreach($mArray as $key => $array) {
foreach($array as $k => $v) {
$query_string .= 'item[' . urlencode($key) . '][' . urlencode($k) . ']=' . urlencode($v) . '&';
}
}
$query_string = substr($query_string, 0, 1); // trim extra &
If you needed to handle arrays of arbitrary dimensions, you could obviously modify this into a function which could be called recursively to get to as many levels as possible.
$mArray be somewhere in the URL?
item as the parameter name as you didn't specify what the name was you wanted the parameter passed as. You can simply substitute item for whatever parameter name you choose.$mArray and pass to another page via $_GET, so you needed to build the query string. No matter the logic is the same. If you are trying to populate $mArray from a GET request you just need to have the query string formatted as I have shown.
