## 説明

pg_field_prtlen() returns the actual printed length (number of characters) of a specific value in a PostgreSQL result. Row numbering starts at 0. This function will return FALSE on an error. field_name_or_number can be passed either as an integer or as a string. If it is passed as an integer, PHP recognises it as the field number, otherwise as field name. See the example given at the pg_field_name() page. Note: This function used to be called pg_fieldprtlen().

## 戻り値
