How to properly deserialize a string from JQuery using PHP? [duplicate] - php

JQuery string not parsing correctly in PHP
(2 answers)
Closed 9 years ago.
I was wondering, does anyone know how do I properly deserialize a string from a JQuery using PHP? The string that JQuery passes into my PHP file is this:
age_gender=1&age_gender=2&age_gender=3&age_gender=4&age_gender=5&age_gender=6
The values I need are the numbers after the equal signs (they are just dummy values that I used for testing).
EDIT: Actually, I am already using parse_str(). Here is my PHP code:
if(isset($_POST['age_gender'])) {
$formSerialized = $_POST['age_gender'];
$formData = array();
parse_str($formSerialized, $formData);
addRow($formData, $link);
}
function addRow($dataArray, $link) {
$age_group = $dataArray[0];
$populations = array(intval($dataArray[1]) + intval($dataArray[2]), intval($dataArray[1]), intval($dataArray[2]));
$percents = array(doubleval($dataArray[3]) + doubleval($dataArray[4]), doubleval($dataArray[3]), doubleval($dataArray[4]));
$m_per_100_f = doubleval($dataArray[6]);
$query = "INSERT INTO national_age_gender_demographics (age_group, both_pop, male_pop, female_pop, both_percent, male_percent, female_percent, males_per_100_females)
VALUES ('$age_group','$populations[0]','$populations[1]','$populations[2]','$percents[0]','$percents[1]','$percents[2]','$m_per_100_f')";
$result = mysqli_query($link,$query);
if(!$result) die( "Query: " . $query . "\nError:" . mysql_error() );
}
For some reason, I am getting a blank string for $age_group, and 0's for all other values. Could anyone help me here?

Answer 1

See parse_str()
Example:
parse_str('age_gender=1&age_gender=2&age_gender=3&age_gender=4&age_gender=5&age_gender=6', $output);
print_r($output);
Also if you want to get the querystring of the request you can get it with php using $_SERVER['QUERY_STRING']

Answer 2

parse_str()
is the function you are looking for.
You have two options to use with this:
parse_str($string) - this will actually create a variable for each key in the string.
parse_str($string,$arr) - this will populate $arr with an associative array containing all the key=>value pairs from the string.
The documentation gives some great code to demonstrate this behavior:
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first; // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz
parse_str($str, $output);
echo $output['first']; // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz
