pg_convert

(PHP 4 >= 4.3.0, PHP 5, PHP 7)

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

Description

array pg_convert ( resource $connection , string $table_name , array $assoc_array [, int $options = 0 ] )

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 constant TRUE in assoc_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 or PGSQL_CONV_IGNORE_NOT_NULL, combined.

Return Values

An array of converted values, or FALSE on error.
