Beginner help needed :)
I am doign an example form a php book which lists tables in databases. I am getting an error on line 36: $db_list .= "$table_list";
<?php
//connect to database
$connection = mysql_connect("localhost", "admin_cantsayno", "cantsayno")
or die(mysql_error());
//list databases
$dbs = @mysql_list_dbs($connection) or die(mysql_error());
//start first bullet list
$db_list = "<ul>";
$db_num = 0;
//loop through results of functions
while ($db_num < mysql_num_rows($dbs)) {
//get database names and make each a list point
$db_names[$db_num] = mysql_tablename($dbs, $db_num);
$db_list .= "<li>$db_names[$db_num]";
//get table names and make another list
$tables = @mysql_list_tables($db_names[$db_num]) or die(mysql_error());
$table_list = "<ul>";
$table_num = 0;
//loop through results of function
while ($table_num < mysql_num_rows($tables)){
//get table names and make each bullet point
$table_names[$table_num] = mysql_tablename($tables, $table_num);
$table_list .= "<li>$table_names[$table_num]";
$table_num++;
}
//close inner bullet list and increment number to continue
$table_list .= "</ul>"
$db_list .= "$table_list";
$db_num++;
}
//close outer bullet list
$db_list .= "</ul>";
?>
