Interpretation of the details of PHP code specifications
As the PHP language becomes more and more widely used, good code specifications have become particularly important. By adhering to code specifications, we can improve the readability, maintainability, and scalability of the code, thereby improving development efficiency and code quality. This article will explain some details of PHP code specifications and attach code examples.
Indentation and Space Characters
Sample code:
function add($a, $b) { return $a + $b; }
Code line length
Sample code:
$result = add($a, $b) + add($c, $d) + add($e, $f);

Optimized sample code:
if (!checkConditions($condition1, $condition2, $condition3)) { return; } // 执行的业务逻辑
By following the above code specifications, we can write the structure Clear, easy-to-maintain PHP code.
