ID: 53127 Updated by: [email protected] Reported by: nakamura at nepsys dot ddo dot jp Summary: pg_escape_bytea returns a format different from the expectation -Status: Open +Status: Wont fix Type: Bug Package: PostgreSQL related Operating System: Linux kernel 2.6.27 PHP Version: 5.3.3 Block user comment: N New Comment: There's no way in the PQ API to choose the old escaping behaviour -- which behaviour is used depends on the PostgreSQL server version, if the connection is active. Previous Comments: ------------------------------------------------------------------------ [2010-10-21 13:26:21] nakamura at nepsys dot ddo dot jp Description: ------------ Using PostgreSQL 9.0.1, pg_escape_bytea function returns new "hex" format. By defaults, PostgreSQL outputs new "hex" format for bytea data. It is possible to change to "escape" format by modifying the postgresql.conf file. I expecting the test script displays "AAA" always. However, pg_escape_bytea actually returns a different ("hex") format while the database is connected. After disconnected, pg_escape_bytea returns correct ("escape") format. Test script: --------------- <?php $link = pg_connect('dbname=template1 user=postgres'); $version = pg_version($link); print "PostgreSQL version information\n"; var_dump($version); $result = pg_query($link,"show bytea_output"); $col = pg_fetch_row($result,0); pg_free_result($result); print "environment variable: bytea_output\n"; var_dump($col); print "pg_escape_bytea('AAA') before database connection closing\n"; print pg_escape_bytea('AAA')."\n"; pg_close($link); print "pg_escape_bytea('AAA') after database connection closing\n"; print pg_escape_bytea('AAA')."\n"; Expected result: ---------------- PostgreSQL version information array(3) { ["client"]=> string(5) "9.0.1" ["protocol"]=> int(3) ["server"]=> string(5) "9.0.1" } environment variable: bytea_output array(1) { [0]=> string(6) "escape" } pg_escape_bytea('AAA') before database connection closing AAA pg_escape_bytea('AAA') after database connection closing AAA Actual result: -------------- PostgreSQL version information array(3) { ["client"]=> string(5) "9.0.1" ["protocol"]=> int(3) ["server"]=> string(5) "9.0.1" } environment variable: bytea_output array(1) { [0]=> string(6) "escape" } pg_escape_bytea('AAA') before database connection closing \\x414141 pg_escape_bytea('AAA') after database connection closing AAA ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53127&edit=1
