Bug #77913 [NEW]: error_log via syslog: PHP will split msg on line break

From: whissi at whissi dot de Operating system: PHP version: 7.3.4 Package: *General Issues Bug Type: Bug Bug description:error_log via syslog: PHP will split msg on line break Description: ------------ PHP 7.3 introduced "syslog.filter" to control content send to syslog. According to documentation (https://www.php.net/manual/en/errorfunc.configuration.php#ini.syslog.filter), "syslog.filter=all" should allow all characters (=same behavior like in PHP 7.2 or before). However, even when set "syslog.filter=all" to allow all characters including line breaks, when you now send a multi-line message via error_log() through syslog, PHP splits message on line break so you end up with multiple messages instead of sending one single message like before. Test script: --------------- <?php $message = "This is line #1" . PHP_EOL; $message .= "This is line #2"; $iniSetting = ini_get('error_log'); if ($iniSetting !== 'syslog') { die("You must set error_log=syslog!"); } if (version_compare(phpversion(), '7.3', '>')) { $iniSetting = ini_get('syslog.filter'); if ($iniSetting !== 'all') { die("You must set syslog.filter=all!"); } } error_log($message); print "Now please review your syslog!" . PHP_EOL; Expected result: ---------------- When running test script like > /usr/bin/php7.3 -d error_log=syslog -d syslog.filter=all test.php I would expect one single syslog message like > Apr 16 16:52:06 myhost php: This is line #1#012This is line #2 Actual result: -------------- I am getting _two_ messages: > Apr 16 16:53:20 myhost php: This is line #1 > Apr 16 16:53:20 myhost php: This is line #2 -- Edit bug report at https://bugs.php.net/bug.php?id=77913&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=77913&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=77913&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=77913&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=77913&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=77913&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=77913&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=77913&r=needscript Try newer version: https://bugs.php.net/fix.php?id=77913&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=77913&r=support Expected behavior: https://bugs.php.net/fix.php?id=77913&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=77913&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=77913&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=77913&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=77913&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=77913&r=dst IIS Stability: https://bugs.php.net/fix.php?id=77913&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=77913&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=77913&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=77913&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=77913&r=mysqlcfg
