pg_escape_literal - Escape a literal for insertion into a text field
Code Examples

pg_escape_literal( [PgSql\Connection$connection], string$data ): string

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.


This function has internal escape code and can also be used with PostgreSQL 8.4 or less.



An PgSql\Connection instance. When connection is unspecified, the default connection is used. The default connection is the last connection made by pg_connect or pg_pconnect.


As of PHP 8.1.0, using the default connection is deprecated.


A string containing text to be escaped.

Return Values

A string containing the escaped data.


Version Description
8.1.0 The connection parameter expects an PgSql\Connection instance now; previously, a resource was expected.
