Question

Why does this pdo::mysql code crash on windows???

<?php
$username = "root";
$password = "";

try {
    $dsn = "mysql:host=localhost;dbname=employees";
    $dbh = new PDO($dsn, $username, $password);
    $dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, FALSE);
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

echo "Connected to database<br />" ;

$dbh->exec("DROP TABLE IF EXISTS vCard;");
$dbh->exec("DROP TABLE IF EXISTS emp;");

$table = "CREATE TABLE vCard(
    id INT(4) NOT NULL PRIMARY KEY, 
    firstName VARCHAR (255), 
    lastName VARCHAR (255), 
    office VARCHAR (255), 
    homePh VARCHAR (13), 
    mobilePh VARCHAR (13))";

$dbh->exec($table);

$dbh->beginTransaction();

$dbh->exec("INSERT INTO vCard(id, firstName, lastName, office, homePh, mobilePh)
    VALUES (4834, 'Randy', 'Lewis', 'SR. Front End Developer', '631-842-3375', '917-435-2245');");

$dbh->exec("INSERT INTO vCard(id, firstName, lastName, office, homePh, mobilePh)    
    VALUES (0766, 'Frank', 'LaGuy', 'Graphic Designer', '631-789-8244', '917-324-9897');");

$dbh->exec("INSERT INTO vCard(id, firstName, lastName, office, homePh, mobilePh)    
    VALUES (6684, 'Donnie', 'Dolemite', 'COO', '631-789-9482', '917-234-1222');");

$dbh->exec("INSERT INTO vCard(id, firstName, lastName, office, homePh, mobilePh)    
    VALUES (8569, '', 'McLovin', 'Actor', '631-842-9786', '917-987-8944');");

$dbh->commit();

echo "Data entered successfully<br/><br/>";

    $sql = "SELECT * FROM vCard"; // WHERE firstName = 'Donnie'";

    $results = $dbh->query($sql);

    foreach ($results as $id){
        echo "SSN: ". $id['id']." ";
        echo "First Name: ". $id['firstName']." ";
        echo "Last Name: ". $id['lastName']."<br/>";
    }

}   
catch (PDOException $e) {
    echo "Failed: " . $e->getMessage();
    $dbh->rollback();
}   

?>

basically this line of code is what triggers Apache to crash..

    $sql = "SELECT * FROM vCard"; 

If I try to select one value like ‘id’ it’ll … when I try to select more than one value “*” it crashes??????

Answer 1

The right way is to recompile mysql mysqli and pdo_mysql php modules with the good mysql headers (from mysql sources)

But setting up the good dev environment is hard (Windows SDK, VC6 command line, and all needed libs)

In fact, there are protocol versions (you can see in mysql headers, a file named version.h).

I make that for my WAMP package, named EWS – Easy Web Server, for each new release
