Export Mysql data to CSV (also from diferent tables)

[michaelG13]

Hello,
Im new to that kind of code so forgive me.

I have 3 diferent tables

players:
id_player
name_player

players_details:
id_player
position
age

players_eval:
id_player
value
wage

You can see that the ‘id_player’ is in all tables. Now, what i want to do is export on csv and if the ‘id_player’ is the same number with the other tables to continew and show the rest of the info i have on the mysql. Also i would like when the 'id_player' to rename to Player ID on the excel file or 'age' to Age etc.

This is the code im using

$table="players"; // this is the tablename that you want to export to csv from mysql.

function exportMysqlToCsv($table);
{
    $csv_terminated = "\n";
    $csv_separator = ",";
    $csv_enclosed = '"';
    $csv_escaped = "\\";
    $sql_query = "select * from $table";
 
    // Gets the data from the database
    $result = mysql_query($sql_query);
    $fields_cnt = mysql_num_fields($result);
 
 
    $schema_insert = '';
 
    for ($i = 0; $i < $fields_cnt; $i++)
    {
        $l = $csv_enclosed . str_replace($csv_enclosed, $csv_escaped . $csv_enclosed,
            stripslashes(mysql_field_name($result, $i))) . $csv_enclosed;
        $schema_insert .= $l;
        $schema_insert .= $csv_separator;
    } // end for
 
    $out = trim(substr($schema_insert, 0, -1));
    $out .= $csv_terminated;
 
    // Format the data
    while ($row = mysql_fetch_array($result))
    {
        $schema_insert = '';
        for ($j = 0; $j < $fields_cnt; $j++)
        {
            if ($row[$j] == '0' || $row[$j] != '')
            {
 
                if ($csv_enclosed == '')
                {
                    $schema_insert .= $row[$j];
                } else
                {
                    $schema_insert .= $csv_enclosed . 
					str_replace($csv_enclosed, $csv_escaped . $csv_enclosed, $row[$j]) . $csv_enclosed;
                }
            } else
            {
                $schema_insert .= '';
            }
 
            if ($j < $fields_cnt - 1)
            {
                $schema_insert .= $csv_separator;
            }
        } // end for
 
        $out .= $schema_insert;
        $out .= $csv_terminated;

    } // end while
$file = "testing";
 $filename = $file."_".date("Y-m-d_H-i",time());
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Length: " . strlen($out));
    // Output to browser with appropriate mime type, you choose ;)
    //header("Content-type: text/x-csv");
    //header("Content-type: text/csv");
    header("Content-type: application/csv");
    header("Content-disposition: csv" . date("Y-m-d") . ".csv");
    //header("Content-Disposition: attachment; filename=$filename".csv");
    header( "Content-disposition: attachment; filename=".$filename.".csv");
    echo $out;
    exit;
}

I really need your help

Thank you
