pg_convert — Convert associative array values into forms suitable for SQL statements

Description

pg_convert(
    PgSql\Connection $connection,
    string $table_name,
    array $values,
    int $flags = 0
): array|false

pg_convert() checks and converts the values in values into suitable values for use in an SQL statement. Precondition for pg_convert() is the existence of a table table_name which has at least as many columns as values has elements. The fieldnames in table_name must match the indices in values and the corresponding datatypes must be compatible. Returns an array with the converted values on success, false otherwise.

Note:
Boolean values are accepted and converted to PostgreSQL booleans. String representations of boolean values are also supported. null is converted to PostgreSQL NULL.

Parameters

connection: An PgSql\Connection instance.
table_name: Name of the table against which to convert types.
values: Data to be converted.
flags: Any number of PGSQL_CONV_IGNORE_DEFAULT, PGSQL_CONV_FORCE_NULL or PGSQL_CONV_IGNORE_NOT_NULL, combined.

Return Values

An array of converted values, or false on failure.

Errors/Exceptions

A ValueError or TypeError is thrown when the value or type of field does not match properly with a PostgreSQL's type.

Changelog

Version	Description
8.3.0	Now throws a ValueError or TypeError error when the value or type of field does not match properly with a PostgreSQL's type; previously an `E_WARNING` was emitted.
8.1.0	The `connection` parameter expects an PgSql\Connection instance now; previously, a resource was expected.
