pg_escape_literal — Escape a literal for insertion into a text field
pg_escape_literal() escapes a literal for querying the PostgreSQL database. It returns an escaped literal in the PostgreSQL format. pg_escape_literal() adds quotes before and after data. Users should not add quotes. Use of this function is recommended instead of pg_escape_string(). If the type of the column is bytea, pg_escape_bytea() must be used instead. For escaping identifiers (e.g. table, field names), pg_escape_identifier() must be used.
Hinweis:
This function has internal escape code and can also be used with PostgreSQL 8.4 or less.
connectionEine PgSql\Connection-Instanz.
Falls connection nicht angegeben wurde, wird die Standardverbindung benutzt.
Das ist die zuletzt mit pg_connect() oder pg_pconnect() aufgebaute Verbindung.
Seit PHP 8.1.0 ist die Verwendung der Standardverbindung veraltet.
dataA string containing text to be escaped.
A string containing the escaped data.

Beispiel #1 pg_escape_literal() example
<?php
// Connect to the database
$dbconn = pg_connect('dbname=foo');
// Read in a text file (containing apostrophes and backslashes)
$data = file_get_contents('letter.txt');
// Escape the text data
$escaped = pg_escape_literal($data);
// Insert it into the database. Note that no quotes around {$escaped}
pg_query("INSERT INTO correspondence (name, data) VALUES ('My letter', {$escaped})");
?>
