Issue

It is a good idea to occasionally save the php.log file and start a new one, to help prevent the log from growing too large.  Linux users can use the logrotate utility to do this, but there is no logrotate utility on the IBM i.  This article describes a simple method to periodically rename the php.log file and let a new one be created.

Environment

Zend Server for IBM i on any supported version of IBM i running Zend Server 9.x - 2018.0.x

One simple way to rotate the php.log file is with a CL program set up to run in the IBM Job Scheduler. The source for the CL program could look like this:

PGM
DCL        VAR(&TIMESTAMP) TYPE(*CHAR) LEN(20)
DCL        VAR(&NEWNAME) TYPE(*CHAR) LEN(30)
RTVSYSVAL  SYSVAL(QDATETIME) RTNVAR(&TIMESTAMP)
CHGVAR     VAR(&NEWNAME) VALUE('php.log.' *CAT &TIMESTAMP)
RNM        OBJ('/usr/local/zendphp7/var/log/php.log') +
             NEWOBJ(&NEWNAME)
ENDPGM


This will append a timestamp to the end of the php.log file name. The next time PHP needs to write a php.log entry, it will create a new php.log file.  You can run this CL program periodically using the Job Scheduler. Once a week might be a good choice. 

Once in a while go to the /usr/local/zendphp7/var/log directory and delete the old renamed files.

Previous versions:


Note: For Zend Server 6 - 8.x customers

The location of the php.log file is /usr/local/zendsvr6/var/log/php.log.  Please adjust the above CL source accordingly.


Note: For Zend Server 5 customers

The location of the php.log file is /usr/local/zendsvr/var/log/php.log.  Please adjust the above CL source accordingly.
