重构/获取 PHP 函数的源代码 [英] Reconstruct / get source code of a PHP function

问题描述

我可以通过函数名称以编程方式获取函数的源代码吗?

Can I programmatically get the source code of a function by its name?

喜欢:

function blah($a, $b) { return $a*$b; }
echo getFunctionCode("blah");

有可能吗?

有没有php自描述函数来重构函数/类代码?(我的意思是不要从源文件中获取源代码.)

Are there any php self-descriptive functions to reconstruct function/class code? (I mean instead of getting source code right from the source file.)

推荐答案

扩展使用 ReflectionFunction 的建议，您可以使用以下内容:

Expanding on the suggestion to use the ReflectionFunction, you could use something like this:

$func = new ReflectionFunction('myfunction');
$filename = $func->getFileName();
$start_line = $func->getStartLine() - 1; // it's actually - 1, otherwise you wont get the function() block
$end_line = $func->getEndLine();
$length = $end_line - $start_line;

$source = file($filename);
$body = implode("", array_slice($source, $start_line, $length));
print_r($body);
