pg_escape_string — Escape a string for insertion into a text field

### Description

string pg_escape_string ([ resource `$connection` ], string `$data` )

pg_escape_string() escapes a string for insertion into the database. It returns an escaped string in the PostgreSQL format. Use of this function is recommended instead of addslashes(). If the type of the column is bytea, pg_escape_bytea() must be used instead.

> Note: This function requires PostgreSQL 7.2 or later.

### Parameters

`connection`

  PostgreSQL database connection resource. When `connection` is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

`data`

  A string containing text to be escaped.

### Return Values

A string containing the escaped data.
