如何将PHP数组作为JSON数组传递给Javascript

Currently I am doing the POST Operation to PHP file from the Javascript to perform the operation in PHP and get the response, But in the php file I am having the Array and I wanted to receive it to JavaScript as JSON Array How Can I do that

Java Script

$scope.details = function() {
  $http({
    method: 'POST',
    url: 'myjson.json'
  }).then(function(response) 
  })

PHP Code

 <?php

header('Content-Type: application/json');
// index.php
// Run the parallel get and print the total time
$s = microtime(true);
// Define the URLs
$urls = array(
  "url1",
  "url2",
  "url3"
);
$pg = new ParallelGet($urls);
//print "<br />total time: ".round(microtime(true) - $s, 4)." seconds";

// Class to run parallel GET requests and return the transfer
class ParallelGet
{
  function __construct($urls)
  {
    // Create get requests for each URL
    $mh = curl_multi_init();
    $headers = array(
    'authorization: Basic xyz',
    'cache-control' => 'no-cache',
    'Accept:application/json'
  );
    foreach($urls as $i => $url)
    {
      $ch[$i] = curl_init($url);
      curl_setopt($ch[$i], CURLOPT_SSL_VERIFYHOST, 0);
      curl_setopt($ch[$i], CURLOPT_SSL_VERIFYPEER, 0);
      curl_setopt($ch[$i], CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch[$i], CURLOPT_HTTPHEADER, $headers);
      curl_multi_add_handle($mh, $ch[$i]);
    }

    // Start performing the request
    do {
        $execReturnValue = curl_multi_exec($mh, $runningHandles);
    } while ($execReturnValue == CURLM_CALL_MULTI_PERFORM);
    // Loop and continue processing the request
    while ($runningHandles && $execReturnValue == CURLM_OK) {
      // Wait forever for network
      $numberReady = curl_multi_select($mh);
      if ($numberReady != -1) {
        // Pull in any new data, or at least handle timeouts
        do {
          $execReturnValue = curl_multi_exec($mh, $runningHandles);
        } while ($execReturnValue == CURLM_CALL_MULTI_PERFORM);
      }
    }

    // Check for any errors
    if ($execReturnValue != CURLM_OK) {
      trigger_error("Curl multi read error $execReturnValue
", E_USER_WARNING);
    }

    // Extract the content
    foreach($urls as $i => $url)
    {
      // Check for errors
      $curlError = curl_error($ch[$i]);
      if($curlError == "") {
        $res[$i] = curl_multi_getcontent($ch[$i]);
        //$finalResponse[] = $res[$i]->load();
      } else {
        print "Curl error on handle $i: $curlError
";
      }
      // Remove and close the handle
      curl_multi_remove_handle($mh, $ch[$i]);
      curl_close($ch[$i]);

    }
    // Clean up the curl_multi handle
    curl_multi_close($mh);
      //print_r($res);
    $responseArray = $res;
    // Print the response data

  $responseMSO = json_encode($res);
//print_r(utf8_encode(json_encode($res)));
  //echo $finalResponse[1];
  //echo $responseMSO;
  }

}
?>

Now I want to send these to Javascript as JSONArray

I have seen the suggestion to use json_encode in PHP but when I use that I am getting response as utf-encoded.

Any one please help here

I have referred all the below but didn't help much

    Try this:

    <?php 
    
    $myarray = array('{ "name":"中", "age":30, "car":null }','{ "name":"Mike", "age":32, "car":null }');
    foreach ($myarray as $array) {
        $arrays[] = json_decode($array);
    }
    
    echo json_encode($arrays, JSON_UNESCAPED_UNICODE);
    echo '<br>';
    echo json_encode($arrays);
    
    ?>
    

    As you can see the first sample has unescaped unicode

    OUTPUT:

    [{"name":"中","age":30,"car":null},{"name":"Mike","age":32,"car":null}] [{"name":"\u4e2d","age":30,"car":null},{"name":"Mike","age":32,"car":null}]

    Now I want to send these to Javascript as JSONArray like below

    [{ "name":"John", "age":30, "car":null },{ "name":"Mike", "age":32, "car":null }]

    OK so set up php array first:

    $myarray = array(
            array(
                'name' => 'John',
                'age'  => 30,
                'car'  => null
            ),
            array(
                'name' => 'Mike',
                'age'  => 32,
                'car'  => null
            )
    );
    

    then json encode it in php

    echo  json_encode($myarray);
    

    Result:[{"name":"John","age":30,"car":null},{"name":"Mike","age":32,"car":null}]

    For more details on proper way to send a json response from php using json take a look at this: Returning JSON from a PHP Script

    If you wish to convert an array of objects in PHP and have it JSON-encoded so that JavaScript can use the result, here's one way to accomplish that feat:

    <?php
    
    
    $o = new stdClass;
    $o->name = "John";
    $o->age = 30;
    $o->car =null;
    
    $o2 = new stdClass;
    $o2->name = "Mike";
    $o2->age = 32;
    $o2->car =null;
    
    $myarray = [$o, $o2];
    
    var_dump(json_encode($myarray));
    
    // result:
     "[{"name":"John","age":30,"car":null},{"name":"Mike","age":32,"car":null}]"
    

    see example here.

    For the json-encoded PHP array of objects to be useful for JavaScript it needs to be enclosed in single quotes and then parsed with JSON, as follows:

    <script language="JavaScript">
    var obj = JSON.parse('<?php echo json_encode($myarray) ?>');
    console.log(obj[0].name + "\t" + obj[1].name); // John   Mike
    </script>
    

    See useful resource here and this discussion.
