mysql不显示所有数据库

Question

I'm trying to list all my databases. But I only return information schema and one other table.. I checked my user settings/privileges in mysql and I have access to everything.. How can I return all databases

here is the code i used:

$set = mysql_query('SHOW DATABASES;'); 
$dbs = array(); 
while($db = mysql_fetch_row($set)) $dbs[] = $db[0]; echo implode('<br/>', $dbs);

As pointed out in the comments, you really should start using mysqli instead of mysql.

This should solve your problem though:

<?php

$link = mysqli_connect("localhost", "mysql_username", "mysql_password");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$res = mysqli_query($link, "SHOW DATABASES");

while ($row = mysqli_fetch_assoc($res)) {
    var_dump($row['Database']);
}
