代码行的 PSR-2 和 "Line exceeds by 120 characters"

Question

我正在尝试为 PSR-2 PHP 标准编写一些代码。

在验证时我遇到了很多这样的错误：

Line exceeds 120 characters; contains 122 characters

我已经尝试了几种方法来解决这个问题。这是原始行：

$s = sprintf('%.2F %.2F %.2F %.2F re %s ',$this->x*$k,($this->h-$this->y)*$k,$w*$k,-$h*$k,$op);

//Same Codeline with added spaces

$s = sprintf('%.2F %.2F %.2F %.2F re %s ', $this->x * $k, ($this->h - $this->y) * $k, $w * $k, -$h * $k, $op);

我试过这样做：

$s = sprintf(
   '%.2F %.2F %.2F %.2F re %s ',
    $this->x * $k,
    ($this->h - $this->y) * $k,
    $w * $k,
    -$h * $k,
    $op
);

但随后错误变为 "Opening parenthesis of a multi-line function call must be the last content on the line"

我也试过这个：

$he1p = $this->x * $k;
$h3lp = ($this->h - $this->y) * $k;
$s = sprintf('%.2F %.2F %.2F %.2F re %s ', $he1p, $h3lp, $w * $k, -$h * $k, $op);

...但似乎不需要将其分解为多个语句。

Answer 1

But then the Error changed to "Opening parenthesis of a multi-line function call must be the last content on the line"

您在 sprintf( 之后有一个空的 space 字符，而该行中的最后一个字符应该是左括号，因为错误状态是

尝试在 sprintf(

之后删除 space

$s = sprintf(
   '%.2F %.2F %.2F %.2F re %s ',
    $this->x * $k,
    ($this->h - $this->y) * $k,
    $w * $k,
    -$h * $k,
    $op
);
