string maxdb_real_escape_string (resource $link, string $escapestr) DESCRIPTION
Object oriented style string maxdb::real_escape_string (string $escapestr) This function is used to create a legal SQL string that you can use in an SQL statement. The string escapestr is encoded to an escaped SQL string, taking into account the current character set of the connection. Characters encoded are ', ". RETURN VALUES
Returns an escaped string. EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city"); $city = "'s Hertogenbosch"; /* this query will fail, cause we didn't escape $city */ if (!$maxdb->query("INSERT into temp.mycity VALUES ('11111','$city','NY')")) { printf("Error: %s ", $maxdb->sqlstate); } $city = $maxdb->real_escape_string($city); /* this query with escaped $city will work */ if ($maxdb->query("INSERT into temp.mycity VALUES ('22222','$city','NY')")) { printf("%d Row inserted. ", $maxdb->affected_rows); } $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city"); $city = "'s Hertogenbosch"; /* this query will fail, cause we didn't escape $city */ if (!maxdb_query($link, "INSERT into temp.mycity VALUES ('11111','$city','NY')")) { printf("Error: %s ", maxdb_sqlstate($link)); } $city = maxdb_real_escape_string($link, $city); /* this query with escaped $city will work */ if (maxdb_query($link, "INSERT into temp.mycity VALUES ('22222','$city','NY')")) { printf("%d Row inserted. ", maxdb_affected_rows($link)); } maxdb_close($link); ?> The above example will output something similar to: Warning: maxdb_query(): -5016 POS(43) Missing delimiter: ) <...> Error: 42000 1 Row inserted.
