Question

This might be easy for you guys but i could’t get it.

I have a php class that query the database and return the query result. I assign the result to an array and wants to use it on my main.php script. I have tried to use echo $var[0] or
echo $var[1] but the output are ‘array’ instead of my value. Anyone can help me about this issue? Thanks a lot!

My php class

<?php 
class teamQuery {

            function teamQuery(){


            }
            function getAllTeam(){
                $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS);
                    if (!$connection) {
                        die("Database connection failed: " . mysql_error());
                    }

                    $db_select = mysql_select_db(DB_NAME,$connection);
                    if (!$db_select) {
                        die("Database selection failed: " . mysql_error());
                    }

                  $teamQuery=mysql_query("SELECT * FROM team", $connection);

                    if (!$teamQuery){
                        die("database has errors: ".mysql_error());
                          }
                    $ret = array();   

                    while($row=mysql_fetch_array($teamQuery)){

                    $ret[]=$row;
                    }     
                    mysql_free_result($teamQuery); 

                    return $ret;
                    }


            }


?>

My php on the main.php

$getTeam=new teamQuery();
$team=$getTeam->getAllTeam();

   //echo $team[0] or team[1] output 'array' string!
  // while($team){
  // do something }  can't work either

  // How to loop through the values??

Thanks!

Answer 1

You get this output because $team[0] and $team[1] are indeed arrays. They are the rows of your database table and every row consists of several fields, e.g. id, name etc.
You have 2 dimensional array, that might look like this:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => foo
        )

    [1] => Array
        (
            [id] => 2
            [name] => bar
        )
)

To loop through the data, use for or foreach:

foreach($team as $member) {
    foreach($member as $k=>$v) {
        echo $k . ': ' . $v;
    }
}

Also the documentation about arrays might be worth reading for you.
