(PHP 4 >= 4.3.0, PHP 5)

pg_select — Select records

### Description

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

This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.

### Parameters

`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.

### Return Values

Returns `TRUE` on success or `FALSE` on failure. Returns string if `PGSQL_DML_STRING` is passed via `options`.

### Examples

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";
}
?>`
