pg_unescape_bytea - Unescape binary for bytea type
Manual
Code Examples

pg_unescape_bytea( string$string ): string

pg_unescape_bytea unescapes PostgreSQL bytea data values. It returns the unescaped string, possibly containing binary data.

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

string

A string containing PostgreSQL bytea data to be converted into a PHP binary string.

Return Values

A string containing the unescaped data.
