Resultaten van SQL-query's weergeven in php

U moet de gegevens ophalen uit elke rij van de resultatenset die uit de query is verkregen. U kunt mysql_fetch_array() . gebruiken hiervoor.

// Process all rows
while($row = mysql_fetch_array($result)) {
    echo $row['column_name']; // Print a single column data
    echo print_r($row);       // Print the entire row data
}

Verander je code in dit:

require_once('db.php');  
$sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )  FROM  modul1open) 
ORDER BY idM1O LIMIT 1"

$result = mysql_query($sql);
while($row = mysql_fetch_array($result)) {
    echo $row['fieldname']; 
}
