(PHP 4 >= 4.3.0, PHP 5)
pg_convert — Convert associative array values into suitable for SQL statement
$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.
Notă:
Since PHP 5.6.0, it accepts boolean values. It converted to PostgreSQL boolean. String representations of boolean value is 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 no valid entry for boolean fields in PostgreSQL. Use one of t, true, 1, y, yes instead.
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.
An array of converted values, or FALSE
on error.
Example #1 pg_convert() example
<?php
$dbconn = pg_connect('dbname=foo');
$tmp = array(
'author' => 'Joe Thackery',
'year' => 2005,
'title' => 'My Life, by Joe Thackery'
);
$vals = pg_convert($dbconn, 'authors', $tmp);
?>
