PHP is one of the programming languages which were developed with built-in web growth capabilities. The new language features included in PHP 7 further makes it much easier for designers to boost the rate of their web program significantly without deploying additional sources. They designers can switch to the most recent version of the widely used server-side scripting language to improve the load rate of websites without putting additional persistence. But the web program designers still need focus on the readability and reusability of the PHP rule to sustain and upgrade the web programs quickly in future.
12 Tips to Write Fresh, Maintainable, and Reusable PHP Code
1) Take Benefits of Local Functions
While composing PHP rule, the designers have choice to achieve the same objective by using either native features or custom features. But the designers must make built-in features provided by PHP to achieve a variety of tasks without composing additional rule or custom features. The native features will further help the designers to keep the program rule as well as understandable. They can simply gather details about the native features and their utilization by referring to the PHP instructions.
2) Compare Similar Functions
The designers can use native features to keep the PHP rule understandable and clean. But they must remember that the performance rate of individual PHP features varies. Also, certain PHP features consume additional sources than others. Hence, the designers must compare similar PHP features, and choose the one that does not affect the efficiency of the web program negatively and consume additional sources. For example, they must determine the length of a string by using isset() instead of strlen(). In addition to being quicker than strlen(), isset() also continues to be valid regardless of the existence of variables.
3) Storage cache Most PHP Scripts
The PHP designers must remember that the program performance time is different one web server to another. For example, Apache web server serve a HTML page much quicker than PHP programs. Also, it needs to recompile the PHP program everytime the page is requested for. The designers can simply eliminate the program recompilation procedure by caching most programs. They also have choice to reduce the program compilation time significantly by using a variety of PHP caching tools. For example, the designers can use memcache to cache a great variety of programs effectively, along with reducing details source interactions.
4) Perform Depending Code with Ternary Operators
It is a common practice among PHP designers to operate conditional rule with If/Else claims. But the designers have to composing additional rule to operate conditional rule through If/Else claims. They can simply prevent composing additional rule by performing conditional rule through ternary owner instead of If/Else claims. The ternary owner helps designers to keep the rule as well as clutter-free by composing conditional rule within a line.
5) Keep the Code Readable and Maintainable
Often designers find it daunting to understand and modify the rule written by others. Hence, they need additional a chance to sustain and upgrade the PHP programs effectively. While composing PHP rule, the designers can just create the program easy to sustain and upgrade by describing the utilization and significance of individual rule snippets clearly. They can just create the rule understandable with the addition of feedback to each rule snippet. Content will create it simpler for other designers for making changes to the existing rule in future without putting additional persistence.
6) Use JSON instead of XML
While working with web services, the PHP designers have choice to use both XML and JSON. But they can always make native PHP features like json_encode( ) and json_decode( ) to work with web services in a quicker and more efficient way. They still have choice to work with XML form of details. The designers can parse the XML details more effectively by using regular expression instead of DOM manipulation.
7) Pass Sources instead of Value to Functions
The experienced PHP designers never declare new sessions and methods only when they become essential. They also explore ways to reuse the sessions and methods throughout the rule. However, they also understand the fact that a operate can be manipulated quickly by moving references instead of principles. They can further prevent including additional overheads by moving references to the operate instead of principles. However, they still need to ensure that the logic continues to be unaffected while moving reference to the features.
8) Turn Mistake Confirming on in Development Mode
The designers must recognize and repair all mistakes or flaws in the PHP rule during the growth procedure. They also have to put a longer period and attempt to fix the coding mistakes and issues identified during testing procedure. The designers simply set the mistake reporting to E_ALL to recognize both minor and major mistakes in the PHP rule during the growth procedure. However, they must turn the mistake reporting choice off when the program moves from growth method to production method.
9) Replace Dual Quotations with Individual Quotes
While composing PHP rule, designers have choice to use either single quotes (‘) or double quotes (“). But the designers can simply improve the efficiency of the PHP program by using single quotes instead of double quotes. The only rule will increase the performance rate of loops drastically. Likewise, the single quote will further enable designers to print longer lines of details more effectively. However, the designers have for making changes to the PHP rule while using single quotes instead of double quotes.
10) Avoid Using Wildcards in SQL Queries
PHP designers often use wildcards or * to keep the SQL concerns compact and simple. But the use of wildcards may affect the efficiency of the web program directly if the details source has a higher variety of content. The designers must mention the required content specifically in the SQL question to keep details secure and reduce resource consumption.
11) Avoid Executing Database Queries in Loop
The PHP designers can simply improve the web application’s efficiency by not performing details source concerns in cycle. They also have several options to achieve the same results without performing details source concerns in cycle. For example, the designers can use a robust WordPress plug-in like Query Monitor to view the details source concerns along with the rows affected by them. They can even use the debugging plug-in to recognize the slow, duplicate, and erroneous details source concerns.
12) Never Trust Customer Input
The smart PHP designers keep the web program secure by never trusting the feedback submitted by users. They always check, filter and sanitize all user details to protect the program from varying security threats. They can further prevent users from submitting inappropriate or invalid details by using built-in features like filter_var(). The operate will check for appropriate principles while receiving or processing user feedback.
