Software is more of engineering and few of arts. Website is a kind of software that is built on 10+ technologies at minimum and anticipates complex technical issues when it is to be geared as non typical web portal, something that can stand out of the crowd to stimulate user to look into and react.
Even the best website with fantastic designs can be far from perfect application if we don’t take care for web server related security.
OK, let us continue our insights into configurations of PHP and Apache architects that we have started in previous articles.
If you haven’t gone through previous text, you can navigate to and read it at this URL:

So far, we visited parameters and settings from PHP’s end, now we will take a brief tour of parameters from Apache’s end.
When PHP runs as an Apache module, you ought to modify key directives through Apache’s httpd.conf or .htaccess file.
We can set key value pairs with = assignment operator in between.
Apache-to-PHP directives can not be modified from anywhere else except from httpd.conf or .htaccess as stated. Reason is that even if hacker can plug in to website code pages, will essentially unable to touch web server objects.
Interestingly, each directive is also assigned a separate scope, and it can be altered or modified within that realm.
In total, there are four scopes revealed with examples of below four directives:
Now, we will see several directives pertaining to PHP language behaviour. Majority of these given variables can be settled from php.ini itself.
After determining and settling values if you see no effects, consider reading documentation of any special extension like WordPress or CodeIgniter plug-ins your application might have introduced that is overriding key-value pair employed by us.
Only few moments will be spent to get acquainted with these directives and then you will adjust language’s general behaviours according to your taste.
Default value: Off
When major upgradation occurs in a technology software, there remains a gap between past versions and current one in terms of parameters, related thresholds or even their meaning.
Older version elements remain in the use for a time until respected vendor installs patches.
However, even intermediate developers aren’t aware that enabling the zend.ze1_compatibility_mode directive allows older version PHP applications to run without issue in version 5 or greater. Therefore, if you’d like to use
specific application that is unmatched with modern trends, look to this directive.
Default value: On
This parameter is simply responsible for determining whether the PHP engine is enabled.
Beware of its ‘off’ value. Turning it off prevents you from using PHP at all. Obviously, you should not touch upon this directive and leave this enabled.
Default value: On
PHP scripts are essentially enclosed within escape syntax. There are four different escape formats, most commonly used one is the shortest form and looks like this:
echo “any valid statement”;
If you’re a multi-skill web developer, you will notice that this syntax is shared with XML, which would cause issues in certain environments. Therefore, we are provided a means for disabling this particular format in case.
Growth of Apache and PHP have gone infinite and a series of articles are needed to explain each major bit of setting.
We hope text given in these two articles on web server configurations remained meaningful to you and you gained knowledge for the same.
