pg_escape_literal — Escape a literal for insertion into a text field
$connection
], string $data
)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.
Замечание:
This function has internal escape code and can also be used with PostgreSQL 8.4 or less.
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().
When there is no default connection, it raises E_WARNING
and returns FALSE.
dataA string containing text to be escaped.
A string containing the escaped data.
