Another way to check if a table exists:
if(mysql_num_rows(mysql_query("SHOW TABLES LIKE '".$table."'"))==1) echo "Table exists";
else echo "Table does not exist";
(PHP 4, PHP 5)
mysql_tablename — Get table name of field
Questa enstensione deprecata da PHP 5.5.0, e sarà rimossa in futuro. Al suo posto, usare l'estensione MySQLi o PDO_MySQL. Vedere anche la guida MySQL: scelta dell'API e le FAQ relative per ulteriori informazioni. Le alternative a questa funzione includono:
SHOW TABLES
Retrieves the table name from a result.
This function is deprecated. It is preferable to use
mysql_query() to issue an SQL SHOW TABLES
[FROM db_name] [LIKE 'pattern'] statement instead.
resultA result pointer resource that's returned from mysql_list_tables().
iThe integer index (row/table number)
The name of the table on success o false in caso di fallimento.
Use the mysql_tablename() function to traverse this result pointer, or any function for result tables, such as mysql_fetch_array().
Example #1 mysql_tablename() example
<?php
mysql_connect("localhost", "mysql_user", "mysql_password");
$result = mysql_list_tables("mydb");
$num_rows = mysql_num_rows($result);
for ($i = 0; $i < $num_rows; $i++) {
echo "Table: ", mysql_tablename($result, $i), "\n";
}
mysql_free_result($result);
?>Nota:
The mysql_num_rows() function may be used to determine the number of tables in the result pointer.
