To get a list of the tables in the mysql DB...

function exisitingTables()
{
    $result = mysql_query("SHOW TABLES");
    $tables = array();

    if(mysql_num_rows($result))
    {
        while($data = mysql_fetch_array($result, MYSQL_NUM))
        {
            $tables[] = $data[0];
        }
    }

    return $tables;
}

Use it by...

$tables = existingTables();

for example

You can then run something like...

$checkTable = "users";

$res = in_array($checkTable,$tables);

Thanks for helping me DIAFOL. But in the $checkTable variable can i use array?
If i can how can i do. I thik it will be less my code. Cause If i have 100 of tables, I have to use 100 time this function. If u can plz share something.

Sure you can use an intersect to get all the matches...

$checktables = array("thistable","thattable","histable","hertable", "mytable");
$result = array_intersect($checktables, $tables);

The $result will hold all matches - so it will be an array - empty or otherwise.
