Question

When I run :

while($r = mysql_fetch_assoc($result3)) { 

echo json_encode($r); 

}

the results is :

{"test1":"1","test2":"2","test3":"3","test4":"4"}

{"test1":"5","test2":"5","test3":"7","test4":"8"}

my question is :
How can I create arrays from the results above knowing that the number of lines is not fixed, it may change depend on the data. So, I could make changes to the arrays and parse it in a format similar to this :

["test1"=>"1","5"],

["test2"=>"2","6"], 

["test3"=>"3","7"], 

["test4"=>"4", "8"]

Thanks!!

Try this :

<?php

$arr = array();

while ($r = mysql_fetch_assoc($result3)) 
{ 
    foreach ($r as $index=>$item)
    {
        $arr[$index][]=$item;
    }
}

?>

And to encode as JSON (after re-arranging the array) :

$arr = json_encode($arr);
