#48238 [NEW]: pg_escape_string() output should be in E'...', not '...'

From: thuejk at gmail dot com Operating system: All PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: pg_escape_string() output should be in E'...', not '...' Description: ------------ On http://dk.php.net/pg_escape_string you write // Escape the text data $escaped = pg_escape_string($data); // Insert it into the database pg_query("INSERT INTO correspondence (name, data) VALUES ('My letter', '{$escaped}')"); However, on a recent version on postgresql this will produce warnings (in the postgresql log), for example if $data contains backslashes. As they write at http://www.postgresql.org/docs/8.3/interactive/runtime-config-compatible.html : escape_string_warning (boolean) When on, a warning is issued if a backslash (\) appears in an ordinary string literal ('...' syntax) and standard_conforming_strings is off. The default is on. Applications that wish to use backslash as escape should be modified to use escape string syntax (E'...'), because the default behavior of ordinary strings will change in a future release for SQL compatibility. So obviously the PHP manual should be changed to use the future-proof E'{$escaped}' instead of '{$escaped}'. -- Edit bug report at http://bugs.php.net/?id=48238&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48238&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48238&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48238&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48238&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48238&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48238&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48238&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48238&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48238&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48238&r=support Expected behavior: http://bugs.php.net/fix.php?id=48238&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48238&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48238&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48238&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48238&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48238&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48238&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48238&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48238&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48238&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48238&r=mysqlcfg
