HomeBackend DevelopmentPHP Tutorial请问这2种编写代码的风格有何区别?

PHP代码:

<code><?php //写法1:有空格
header( "Content-type:text/html;charset=gbk" );
//写法2:没空格
header("Content-type:text/html;charset=gbk");
?>
</code>

记得之前在哪里看到过,推荐采用写法1,不知道为什么?

这个问题已被关闭,原因:

<code><?php //写法1:有空格
header( "Content-type:text/html;charset=gbk" );
//写法2:没空格
header("Content-type:text/html;charset=gbk");
?>
</code>

记得之前在哪里看到过,推荐采用写法1,不知道为什么?

怎么看顺眼怎么写!

应该没区别,是为了好看吧..
比如说var=a;和var = a;是一样的,我喜欢后者也是为了好看

没区别
比如一个php函数
function fun1($str1, $str2){
}
两个参数中间用逗号隔开,但是为了好看,逗号后面会跟上一个空格

只不过文件大了2个字节而已

第一种写法应该是为了感官上更直接,不会因为代码太紧凑而读起来费劲。

找个编码规范, 按编码规范来

区别还是有的,加了空格,文件大小会变大。哈哈。 个人认为这个属于个人习惯吧,怎么顺眼怎么写。

举个明显点的例子。

<code>for(int i=0,j=0;i</code>

<code>for(int i = 0, j = 0; i </code>

哪个可读性好,很显而易见吧!

两种风格都是没有问题的,也就是说是符合规范的,

但是关键的一点是:

<code>要在代码里从始至终使用一种规范\风格,如果使用以上两种风格\规范混搭,那样的话既不美观,也不正确
</code>

没有区别。编码风格的问题不涉及语法,对编译器来说能认识就好,怎么写都行。但是代码写出来都是要人来看的,所以为了善待自己善待他人,要写清楚。不说其他编码风格,就说这里提到的排版,通过空格、换行、对齐,让代码按照其逻辑来组织(错落有致),对快速理解代码也是很有帮助的。还有很重要的一点是,整个代码整个项目的程序,其风格就应该一致!你写的和其他项目成员写的应该一致!到底是采用这种风格还是那种风格就反而没那么重要了。

zend studio 默认格式化就是第一种,不过平常更多的是第二中的规范,主要还是要看整体代码的规范统一即可!

How to calculate the total number of elements in a PHP multidimensional array?How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.
