Step By Step Instructions To Enable Clean URLs in Drupal

By default, Wamp Server doesn't support clean url feature of drupal cms.
To enable Clean URLs we need to manually edit the httpd.conf file of Apache server to support this feature.

1. Start WAMP Server. Click on the WAMP Server icon in the tray. Go to Apache -> httpd.conf as shown in the image below.
2. Find the following line in the httpd.conf file
   #LoadModule rewrite_module modules/mod_rewrite.so
3. Just remove the # symbol in the beginning of that line. Now it looks like in the below line.
    LoadModule rewrite_module modules/mod_rewrite.so
4. Now save the httpd.conf file and Restart your Wamp Server. Then open your browser and enable Clean URLs in your drupal cms.
   Enable Clean URLs From admin -> siteconfiguration.

sort an associative array by one of its keys

In case you need to sort an associative array by one of its keys, this function might be useful:

<?php
function sortByOneKey(array $array, $key, $asc = true) {
    $result = array();
       
    $values = array();
    foreach ($array as $id => $value) {
        $values[$id] = isset($value[$key]) ? $value[$key] : '';
    }
       
    if ($asc) {
        asort($values);
    }
    else {
        arsort($values);
    }
       
    foreach ($values as $key => $value) {
        $result[$key] = $array[$key];
    }
       
    return $result;
}

?>

Consider the following example:

<?php

$users = array(
    1 => array('name' => 'John', 'age' => 35),
    2 => array('name' => 'Alice', 'age' => 23),
    3 => array('name' => 'Bob', 'age' => 26)
);
       
$sortedByNameAsc = sortByOneKey($users, 'name');
$sortedByNameDesc = sortByOneKey($users, 'name', false);
       
echo "Sorted by Name in ascending order: ";
echo "<pre>" . print_r($sortedByNameAsc, true) . "</pre>";
echo "<br /><br />Sorted by Name in descending order: ";
echo "<pre>" . print_r($sortedByNameDesc, true) . "</pre>";

?>

The output will be the following:

Sorted by Name in ascending order:
Array
(
    [2] => Array
        (
            [name] => Alice
            [age] => 23
        )

    [3] => Array
        (
            [name] => Bob
            [age] => 26
        )

    [1] => Array
        (
            [name] => John
            [age] => 35
        )

)

Sorted by Name in descending order:
Array
(
    [1] => Array
        (
            [name] => John
            [age] => 35
        )

    [3] => Array
        (
            [name] => Bob
            [age] => 26
        )

    [2] => Array
        (
            [name] => Alice
            [age] => 23
        )

)
