Php5 en mod (php7-also)

Posted on June 22, 2017June 23, 2018 by coder

After installing php modules, some are not enabled by default upon installation.

One of those modules is php5-imap and php5-mcrypt is another one.

You have to enable them with php5enmod command.

php5enmod works just like the way a2enmod works for Apache.

php5enmod module-name     # to enable php module
php5enmod imap            # to enable php5-imap
php5enmod mcrypt          # to enable php5-mcrypt

php5enmod module-name # to enable php module

php5enmod imap # to enable php5-imap

php5enmod mcrypt # to enable php5-mcrypt

… php5dismod, just like a2dismod works.

enabled php modules with…

php -m                 # for the entire list

php -m | grep imap     # to check for a certain module name

php -m # for the entire list

php -m | grep imap # to check for a certain module name

“php -m” list,

service apache2 reload - restart

1	service apache2 reload - restart

Php Opcache (Php performance Increase – Cache Optimization)

Posted on June 22, 2017June 23, 2018 by coder

A few words about the OPcache.

“OpCode Cache“. “APC” is one of them. “Zend OPcache” is another one; and this Zend OPcache (or OPcache for short) is built into php 5.5, not APC.

The workaround is to disable the OPcache, which is enabled by default. It is a setting in php.ini file.

opcache.enable=0

1	opcache.enable=0

The question has been raised if disabling the OPcache before installation and enabling it right after would be good enough. While I don’t have a solid answer for that, it should be good enough to keep it disabled during installation and upgrades. I permanately turned it off on my test site.

if we can disable the OPcache per site basis. Like disabling it for a DomainCluster sites and enabling it for others.

Yes, can do that.

Developer can disable OPcache per site basis
Developer cannot enable it whenever Developers want it;
It should be enabled by default.
If developer has disabled it through php.ini file, then you need to revert it back.

Placing below line in your “settings.php” file will disable it.

# Php file code
ini_set('opcache.enable', '0');

#Htaccess
php_flag opcache.enable Off

# Php file code

ini_set('opcache.enable', '0');

#Htaccess

php_flag opcache.enable Off

apache config should

has“AllowOverride All” in order to make the .htaccess method work; which is also a requirement for installing & running other properties.

# Worked

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);


# in php.ini   file

// After RESET the web server

<?php error_reporting( E_ALL ); ?>

display_errors = On

error reporting is set to the following in php.ini

error_reporting = E_ALL | E_STRICT


UPDATE 1:

I have changed error_reporting in php.ini from:

error_reporting = E_ALL & ~E_DEPRECATED
to
error_reporting = E_ALL | E_STRICT

/etc/init.d/apache2 restart

<?php error_reporting( E_ALL ); ?>

display_errors = On

error reporting is set to the following in php.ini

error_reporting = E_ALL | E_STRICT
