    pg_escape_string — Escape a string for query

    Descripción

    pg_escape_string(PgSql\Connection$connection = ?, string$data): string

    pg_escape_string() escapes a string for querying the database. It returns an escaped string in the PostgreSQL format without quotes. pg_escape_literal() is more preferred way to escape SQL parameters for PostgreSQL. addslashes() must not be used with PostgreSQL. If the type of the column is bytea, pg_escape_bytea() must be used instead. pg_escape_identifier() must be used to escape identifiers (e.g. table names, field names)

    Nota:

    This function requires PostgreSQL 7.2 or later.

    Parámetros

    connection

    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().

    Advertencia

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

    data

    A string containing text to be escaped.

    Valores devueltos

    A string containing the escaped data.

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