# pg_select

(PHP 4 >= 4.3.0, PHP 5)

pg_select — Select records

### Descripción

mixed pg_select ( resource `$connection` , string `$table_name` , array `$assoc_array` [, int `$options`= PGSQL_DML_EXEC ] )

pg_select() selects records specified by assoc_array which has field=>value. For a successful query, it returns an array containing all records and fields that match the condition specified by assoc_array.

If options is specified, pg_convert() is applied to assoc_array with the specified flags.

Warning

Esta función es EXPERIMENTAL. Esto significa que el comportamiento de esta función, el nombre de esta función y en definitiva TODO lo documentado sobre esta función, puede cambiar en una futura version de PHP SIN AVISO. La advertencia queda hecha, y utilizar esta extensión queda bajo su propia responsabilidad.

### Lista de parámetros

`connection`

  PostgreSQL database connection resource.

`table_name`

  Name of the table from which to select rows.

`assoc_array`

  An array whose keys are field names in the table `table_name` , and whose values are the conditions that a row must meet to be retrieved.

`options`

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

### Valores retornados

Devuelve `TRUE` si todo se llevó a cabo correctamente, `FALSE` en caso de fallo. Returns string if `PGSQL_DML_STRING` is passed via `options` .

### Ejemplos

Example #1 pg_select() example

`<?php
$db = pg_connect('dbname=foo');
// This is safe, since $_POST is converted automatically
$rec = pg_select($db, 'post_log', $_POST);
if ($rec) {
echo "Records selected\n";
var_dump($rec);
} else {
echo "User must have sent wrong inputs\n";
}
?>`
