(PHP 4 >= 4.2.0, PHP 5)

pg_escape_string — Escape a string for insertion into a text field

### 설명

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.

### 인수

  A string containing text to be escaped.

### 반환값
