PDO::quote Quotes a string for use in a query. &reftitle.description; stringPDO::quote stringstring intparameter_type PDO::quote places quotes around the input string (if required) and escapes special characters within the input string, using a quoting style appropriate to the underlying driver. If you are using this function to build SQL statements, you are strongly recommended to use PDO::prepare to prepare SQL statements with bound parameters instead of using PDO::quote to interpolate user input into a SQL statement. Prepared statements with bound parameters are not only more portable, more convenient, immune to SQL injection, but are often much faster to execute than interpolated queries, as both the server and client side can cache a compiled form of the query. Not all PDO drivers implement this method (notably PDO_ODBC). Consider using prepared statements instead. &reftitle.parameters; string The string to be quoted. parameter_type Provides a data type hint for drivers that have alternate quoting styles. The default value is PDO::PARAM_STR. &reftitle.returnvalues; Returns a quoted string that is theoretically safe to pass into an SQL statement. Returns &false; if the driver does not support quoting in this way. &reftitle.examples; quote($string) . "\n"; ?> ]]> &example.outputs; quote($string) .
