如何在不使用 exec() 的情况下在 PHP 中执行 mysqldump？

Question

I am trying to run this code:

$cmd = '/usr/bin/mysqldump --user=myUsername --password="myPassword" --host=localhost myDatabase > myOutputSqlFilePath;
exec($cmd, $output, $return_val);

But it fails, as it seems exec() is not available for PHP on this particular server. (I have confirmed this by trying to run exec("mkdir test-dir", $output, $return_val); which fails to create the test directory.)

So, I would like to know what other options I have to perform the mysqldump in PHP?

Now, I have some related PHP code that creates a database, like this:

function createDb($cPanelUser, $cPanelPass, $dbName) {

    $buildRequest = "/frontend/paper_lantern/sql/addb.html?db=$dbName";

    $openSocket = fsockopen('localhost',2082);
    if(!$openSocket) {
        return "Socket error";
        exit();
    }

    $authString = $cPanelUser . ":" . $cPanelPass;
    $authPass = base64_encode($authString);
    $buildHeaders  = "GET " . $buildRequest ."\r\n";
    $buildHeaders .= "HTTP/1.0\r\n";
    $buildHeaders .= "Host:localhost\r\n";
    $buildHeaders .= "Authorization: Basic " . $authPass . "\r\n";
    $buildHeaders .= "\r\n";

    fputs($openSocket, $buildHeaders);
    while(!feof($openSocket)) {
        fgets($openSocket,128);
    }
    fclose($openSocket);
}

So maybe there is something like this that can be used to perform the mysqldump?

Or maybe there's an entirely different solution??

Answer 1

exec() wasn't available, so in the end I solved this by using mysqli with SHOW CREATE tables and then selecting all the rows, and creating/populating the new database with that data - all with mysqli .
