function Connection::escapeTable

Escapes a table name string.

Force all table names to be strictly alphanumeric-plus-underscore. Database drivers should never wrap the table name in database-specific escape characters. This is done in Connection::prefixTables(). The database-specific escape characters are added in Connection::setPrefix().

Parameters

string $table: An unsanitized table name.

Return value

string The sanitized table name.

    }
