pg_escape_bytea
pg_escape_bytea escapes string for bytea datatype. It returns escaped string.
Note:
When you SELECT a bytea type, PostgreSQL returns octal byte values prefixed with '\' (e.g. \032). Users are supposed to convert back to binary format manually.
This function requires PostgreSQL 7.2 or later. With PostgreSQL 7.2.0 and 7.2.1, bytea values must be cast when you enable multi-byte support. i.e. INSERT INTO test_table (image) VALUES ('$image_escaped'::bytea); PostgreSQL 7.2.2 or later does not need a cast. The exception is when the client and backend character encoding does not match, and there may be multi-byte stream error. User must then cast to bytea to avoid this error.
Parameters
- 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.
Warning:
As of PHP 8.1.0, using the default connection is deprecated.
- data
-
A string containing text or binary data to be inserted into a bytea column.
Return Values
A string containing the escaped data.
