你如何评论PHP功能内的代码？

Question

对于php函数代码，您如何评论代码？这是正确的还是最好的方法？

function menu_element_builder($values) { 
//$links = ''; 
} 

Answer 1

注释行//或#，由您决定。

注释部分行或全部代码块，其中/* [commented code] */。

function menu_element_builder($values/*, $optional_value*/) { 
    #Commented out line 
    echo "Not commented out";  

    //Commented out line 
    echo "Not commented out"; 

    /* Commented out code block 
    echo "Commented out"; */ 

    echo "Not commented out"; //but this is ." and so's this"; 
    echo "Not commented out" /* but this is */ ." and this isn't"; 
    /* This is commented out */ echo "But this isn't"; 
} 

Answer 2

<?php 
// This is a single-line comment 

# This is also a single-line comment 

/* 
This is a multiple-lines comment block 
that spans over multiple 
lines 
*/ 

// Aswell you can use comments to hide part of your code from execution 
$x = 5 /* + 15 */ + 5; 
echo $x; 
?>
