pg_convert

pg_convert

(PHP 4 >= 4.3.0, PHP 5)

pg_convert --  Convert associative array values into suitable for SQL statement

Description

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

pg_convert() checks and converts the values in assoc_array into suitable values for use in a 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: 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 no valid entry for boolean fields in PostgreSQL. Use one of t, true, 1, y, yes instead.
