How To Speed Up The Performance Of Php Website

Speed is a very critical factor when you have a website. Most people have little patience when they open websites, and once web pages on the website begin to open slowly or some applications are taking too much time, they might close the website and quickly move to oppositions. With this, organizations might be losing traffic while blogs will be losing much needed traffic. If you are running a php website or you have some php applications that run on some pages of your website, here are some ways to speed up the performance of the php website or php applications.

Avoid the use of include_once

The include_once structure checks and include a particular file that has been specified when the script is been executed. While it has a similar function with ‘include’, include_once ensures that there is only one inclusion of the file. It is therefore, more resource consuming compared to include station. When it is not absolutely necessary, it might be better to opt for include function.

Do not use double quotes for long strings that have no variable

When you declare a string with double quotes, extra processing is carried out by PHP to discover if there are any potential variables within the strings. For this reason processing:

echo “This is long string $name” will take much more time than processing

echo ‘This is long string’.$name

It is therefore advisable that you opt for using single quotes for variable concatenation combination instead of double quotes as they will process faster. Furthermore, there will be no need for extra manipulation. In the case where there is also no variable in the long string, you should still use single quote as well, so that the program does not take much time looking for strings, while the php script is running.

Try not to use common expressions

Even though common expressions are important, they take a lot of time. It is in the best interest of your website and the users of your website therefore, that you limit the use of common expressions as much as possible. Common expressions have the reputation of taking more time, compared to their counterparts in PHP. As opposed to using preg_replace for instance, it will be better to use str_replace.

When using the echo function, avoid the use of periods

The performance of the echo function is reduced when it is used with periods. This is due to the fact that before outputting them, the strings will be concatenated by PHP. It is advisable to use commas as opposed to using periods. This is because with comma, they are outputted in the order they are declared, implying that there is no need for extra processing and by implication, extra time. The performance of the application will therefore, not be negatively affected when commas are used, instead of periods.

In loops, do not use methods that have object instantiation

PHP is a programming language that is object-oriented. A fundamental aspect of the performance management principles of object-oriented programming languages is not creating too many objects. We are not recommending that you should give up the main object of using object oriented programming languages by not using as many objects as are necessary or as you want. We are however, implying that you should try as much as possible not to create objects in the midst of tight loops, especially when they are loops that are critical to the performance of your code. Creating an object is an operation that is very expensive. It is generally advisable to avoid creating intermediate or temporary objects whenever you can avoid it.

Do not use paths that are relative

If you want a better performance on your PHP website or application, then you should limit relative paths usage for file inclusion. The overall mechanism for the inclusion of relative path will look for default include paths before proceeding with the present directory. Searching for a file will require some time. If you must use paths that are relative, it is best to declare a “WEB_ROOT” constant that will be the definition of the root that you can reuse.

Do not use function tests inside loop conditions

The performance of a PHP application can reduce due to having function tests in loop conditions. If you intend to apply a loop with an array, the calling of the function will occur frequently. Doing a count() prior, to add values to a variable is preferable. There will be no need to execute the test function during every iteration, which is needless.

Avoid using reference to pass function variables

Generally, only values that the parameters have passed are the ones used by functions without changing value from the parameters. For these cases, it is safe to use reference to pass the parameters, for instance function (&$parameter) as opposed to using value (function ($parameter). When you do this, copies that require a lot of memory will be avoided and the performance of the application will be enhanced.

Do not use concatenations of string in loops

When you place a string concatenation in a loop, it leads to a lot of temporary objects been created and garbage collector use unnecessarily. This can result in the consumption of memory and significant reduction in the speed of executing the script.

Do not create variable copies that you will not need

Some developers in a bid to create clean codes often shorten the name of predefined variables. Even though this sounds nice, it however, comes with some cost. The consumption of memory could double when a variable is changed. This will slow down the PHP server.

Conclusion

Following these simple rules could go a long way to help you speed up php server  and subsequently make your website to load faster. It will also help you retain traffic to your site and therefore aid with achieving the aim of your website and to get information about your organization goods and services to the public.
