(PHP 4 >= 4.3.0, PHP 5)

pg_delete -- Deletes records

## Описание

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

pg_delete() deletes records from a table specified by the keys and values in `assoc_array`. If `options` is specified, pg_convert() is applied to `assoc_array` with the specified options.

## Список параметров

`connection`

  PostgreSQL database connection resource.

`table_name`

  Name of the table from which to delete rows.

`assoc_array`

  An array whose keys are field names in the table `table_name`, and whose values are the values of those fields that are to be deleted.

`options`

  Any number of `PGSQL_CONV_FORCE_NULL`, `PGSQL_DML_NO_CONV`, `PGSQL_DML_EXEC` or `PGSQL_DML_STRING` combined. If `PGSQL_DML_STRING` is part of the `options` then query string is returned.

## Возвращаемые значения

Возвращает `TRUE` в случае успешного завершения или `FALSE` в случае возникновения ошибки. Returns string if `PGSQL_DML_STRING` is passed via `options`.

## Примеры

Пример 1. pg_delete() example

`<?php
$db = pg_connect('dbname=foo');
// This is safe, since $_POST is converted automatically
$res = pg_delete($db, 'post_log', $_POST);
if ($res) {
echo "POST data is deleted: $res\n";
} else {
echo "User must have sent wrong inputs\n";
}
?>`
