pg_convert
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
pg_convert — Convert associative array values into forms suitable for SQL statements
Description
$connection
, string $table_name
, array $assoc_array
[, int $options = 0
] ) : array
pg_convert() checks and converts the values in
assoc_array 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 assoc_array has elements. The
fieldnames in table_name must match the indices in
assoc_array and the corresponding datatypes must be
compatible. Returns an array with the converted values on success, FALSE
otherwise.
Note:
Since PHP 5.6.0, it accepts boolean values, converting them to PostgreSQL booleans. String representations of boolean values are also supported.
NULLis converted to PostgreSQL NULL.Prior to PHP 5.6.0, if there are boolean fields in
table_namedon't use the constantTRUEinassoc_array. It will be converted to the string 'TRUE' which is not a valid entry for boolean fields in PostgreSQL. Use one of "t", "true", 1, "y", "yes" instead.
Parameters

connection -
PostgreSQL database connection resource.
-
table_name -
