优雅的换行解决方案(PHP) [英] Elegant solution for line-breaks (PHP)

问题描述

$var = "Hi there"."<br/>"."Welcome to my website"."<br/>;"
echo $var;

是否有一种优雅的方法来处理PHP中的换行符?我不确定其他语言，但是C ++具有eol，这样使用起来更易读易懂吗?

Is there an elegant way to handle line-breaks in PHP? I'm not sure about other languages, but C++ has eol so something thats more readable and elegant to use?

谢谢

推荐答案

我最终编写了一个到目前为止对我有用的函数:

I ended up writing a function that has worked for me well so far:

// pretty print data
function out($data, $label = NULL) {

  $CLI = (php_sapi_name() === 'cli') ? 'cli' : '';

  $gettype = gettype($data);

  if (isset($label)) {
    if ($CLI) { $label = $label . ': '; }
    else { $label = '<b>'.$label.'</b>: '; }
  }

  if ($gettype == 'string' || $gettype == 'integer' || $gettype == 'double' || $gettype == 'boolean') {
    if ($CLI) { echo $label . $data . "\n"; }
    else { echo $label . $data . "<br/>"; }
  }
  else {
    if ($CLI) { echo $label . print_r($data,1) . "\n"; } 
    else { echo $label . "<pre>".print_r($data,1)."</pre>"; }
  }
}


// Usage

out('Hello world!');

$var = 'Hello Stackoverflow!';
out($var, 'Label');
