# pg_update

(PHP 4 CVS only)

pg_update -- Update table.

## Description

long pg_update ( resource connection, string table_name, array condition, array data [, int options])

pg_update() updates records that matches `condition` with `data`. If `options` is specified, pg_convert() is applied to `data` with specified options.

Example 1. pg_update
    <?php
        $db = pg_connect ('dbname=foo');
        $data = array('field1'=>'AA', 'field2'=>'BB');
        // This is safe, since $_POST is converted automatically
        $res = pg_update($db, 'post_log', $_POST, $data);
        if ($res) {
            echo "Data is updated: $res\n";
        }
        else {
            echo "User must have sent wrong inputs\n";
        }
    ?>
