Question

I am using a jQuery autocomplete script but the problem is I do not know what to add correctly inside the search.php file.

this is tutorial jQuery

<?php
$q = strtolower($_GET["q"]);
if (!$q) return;
$items = array(
    "Peter Pan"=>"[e-mail]",
    "Molly"=>"[e-mail]",
    "Dr. Write"=>"[e-mail]"
);

$result = array();
foreach ($items as $key=>$value) {
    if (strpos(strtolower($key), $q) !== false) {
        array_push($result, array(
            "name" => $key,
            "to" => $value
        ));
    }
}
echo json_encode($result);
?>

a working JSON for this jquery is as follow

    [
        {
        label: "anna c13",
        category: "Products"},
    {
        label: "john black",
        category: "Products"},
    {
        label: "anders andersson",
        category: "People"}
    ]

How can I convert my JSON into array like above?

Thank you.

Your PHP should create an Array which itself contains a series of associative arrays. You should then pass that through json_encode and send it to the browser.

Run the code

Code

<?php
//outer array
$responseCollection = Array();


//logic to ceate inner arrays:
for( $i = 1; $i < 5; $i++ )
{
  $responseCollection[] = Array(
    'label' => 'label ' . $i,
    'category' => 'category ' . $i
  );
}

//json encode it
$json = json_encode( $responseCollection );

echo $json;
