Follow These Coding Standards For Core PHP

Typically, every web development company has an entire team of developers dedicated to individual modules in any project. Without having a coding standard to follow, understanding the work of another developer can get overwhelming and time-consuming. While every PHP developer has a coding style, it’s crucial to maintain uniformity for the sake of clarity in understanding the flow and management of the project for future reference.

A coding standard forms a blueprint and facilitates better understanding. A well-written code that is easy to decipher looks professional in the IT industry. Coding by these standards reflects the work quality of a PHP development company and ultimately portrays the developer as a PHP expert. Here are the developer coding standards to follow when working with core PHP:

Indentation – Tabs or Spaces?

While using tab for indentation might be handy, it’s all in vain if the coding structure is distorted when you open it in a different editor. Use four spaces instead to assure consistency in indentation irrespective of the editor chosen.

Optimal Characters per line of code

When you are coding, acknowledge the fact that a peer developer will be referring your code in near future. Every line has to be human readable. Therefore, restrict the line length to somewhere between 75-85 characters.

Conditional Statements Layout

Always include curly braces in the control flow statements like if, for, while, switch (even if they’re optional). Missing out braces makes it harder to trace bugs.

Incorrect

Correct

if (condition)
action1;

if (condition) {
action1;
}

while (condition)
action1;

while (condition) {
action1;
}

for (st1; st2; st3)
action1;

for (st1; st2; st3) {
action1;
}

Add a space between the control keyword, i.e., if, for, while, switch, and the opening parenthesis.

Incorrect

Correct

if(condition) {
action1;
}

if (condition) {
action1;
}

while(condition) {
action1;
}

while (condition) {
action1;
}

for(st1; st2; st3) {
action1;

}

for (st1; st2; st3) {
action1;
}

Function Call Standards
  • Omit any space present between the name of the function and the opening parenthesis.
  • Add a space after every comma in the parameter section, i.e., between every space and parameter.
  • No space should be present between the opening and closing parenthesis and the respective parameters next to them.

$var1 = functionName($param1, $param2, $param3);


Code Delimiting

Always prefer standard PHP delimiting code over the shorthand one. Complying with the standard versions ensures portability in different setups.

Standard Shorthand


<?php ?> <? ?>


Standard Variable Naming Convention
  • Go with lower case for the variable names. Remember that all the letters should be in lower case.
  • In case the name involves more than one word, use underscore ‘_’ to separate them.
  • Global and Static variables should be prepended with ‘g’ and ‘s’ respectively.
Commenting Standards

It is recommended to developers to use // for single-line comments and /* */ to comment out multiple lines of code.

Any professional web development company in USA would certainly follow the above-mentioned standards.
