pg_convert
(PHP 4 >= 4.3.0, PHP 5, PHP 7)
pg_convert — Convert associative array values into forms suitable for SQL statements
Description
pg_convert
( resource $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.
NULL
is converted to PostgreSQL NULL.Prior to PHP 5.6.0, if there are boolean fields in
table_name
don't use the constantTRUE
inassoc_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
- Name of the table against which to convert types.
assoc_array
- Data to be converted.
options
- Any number of
PGSQL_CONV_IGNORE_DEFAULT
,PGSQL_CONV_FORCE_NULL
orPGSQL_CONV_IGNORE_NOT_NULL
, combined.
Return Values
An array of converted values, or FALSE
on error.
