Using array_push in PHP
===

I apologize a head of time for the lengthy/busy question. I am trying to take results from a MySQL query and `base64_encode` the Image blob data, return it to the array and then finally `json_encode` the results so I can use them in my Android application. I know everything on the Android side is set up properly. 

What I have is the following:

**PHP/SQL:**

    $query = "SELECT `locations`.`businessName`, `photos`.`img` 
    		FROM `locations` 
    		JOIN `photos` ON `locations`.`co_id` = `photos`.`co_id` 
    		WHERE `locations`.`businessName` = '".$companyID."'";
    			
    	mysql_connect($dbserver, $dbusername, $dbpassword) or die(mysql_error());
    	mysql_select_db($dbname) or die(mysql_error());
    	
    	$result = mysql_query($query) or die(mysql_error());  
    	$num = mysql_numrows($result);
    	$row = mysql_fetch_assoc($result);
    	
    	$i = 0;
    	$rows = array();
    	while ($i < $num) {
    		
    		$img = mysql_result($result, $i, "img");
    		$finalImg['img'] = base64_encode($img);
    		$businessName['businessName'] = mysql_result($result, $i, "businessName");
    		
    		$finalArray = array_push($rows, $businessName, $finalImg);
    		// I know that array_push is pushing each variable as a separate array item
    		// I tried creating an alternative variable that amends the two together
    		// But that didn't work, result printed [Array, Array] [Array, Array]
    		// Was I on the right track?

    		$i++;
    	}
    	
    	print json_encode($rows);


**Returns 8 results:**

    [0] => {
    	["businessName"]=> string(12) "Some Company" }
    [1] => {
    	["img"]=> string(145968) "/9j/4AAQSkZJRgABAQEAYABgAAD/4QIw..." }


**What I need:** 

I want the results to appear like this, with only 4 results.

    [0] => {
    	["businessName"] => string(12) "Some Company" 
    	["img"] => string(145968) "/9j/4AAQSkZJRgABAQEAYABgAAD/4QIw..." }
    [1] => {
    	["businessName"] => string(12) "Some Company", 
    	["img"] => string(145968) "/9j/4AAQSkZJRgABAQEAYABgAAD/4QIw..." }

**Android Application snippet**:

    jArray = new JSONArray(result);
    for (int i = 0; i < jArray.length(); i++) {
    	JSONObject jObject = jArray.getJSONObject(i);
    	String testerPhoto = jObject.getString("img");
    	//Process image. Base64 decode... etc


**Android Error:**

    07-18 11:28:52.573: E/onPostExecute(14562): FAILED: No value for img
