php - 获取用户定义的类和函数的源代码？

是否有获取类或方法源代码的方法？我正在看ReflectionClass，但没有看到。

最佳答案

最好的我想出了:

$class = new ReflectionClass($c);
$fileName = $class->getFileName();
$startLine = $class->getStartLine()-1; // getStartLine() seems to start after the {, we want to include the signature
$endLine = $class->getEndLine();
$numLines = $endLine - $startLine;

if(!empty($fileName)) {
    $fileContents = file_get_contents($fileName);
    $classSource = trim(implode('',array_slice(file($fileName),$startLine,$numLines))); // not perfect; if the class starts or ends on the same line as something else, this will be incorrect
    $hash = crc32($classSource);
}

编辑:不适用于定义如下的类:

class Foo { }

说这是2行长，当它只能是1时...
