PHP读取文件注释而不是文件内容-忘记了 [英] PHP read file comments NOT file content - forgotten

问题描述

对不起，人们忘记了这个，我需要阅读一个php文件示例中的第一个批处理"注释:

Sorry folks forgotten this one, I need to read the first "batch" of comment in a php file example would be:

<?php
/** This is some basic file info **/
?>
<?php This is the "file" proper" ?>

我需要阅读另一个文件中的第一条评论，但我完全忘记了如何获取/**这是一些基本文件信息**/作为字符串抱歉，但是要感谢

I need to read the first comment inside another file but I have totally forgotten how to get the /** This is some basic file info **/ as a string Sorry but thanks in adavance

推荐答案

有一个token_get_all($code)函数可用于此功能，它比您最初想的要可靠.

There's a token_get_all($code) function which can be used for this and it's more reliable than you first might think.

下面是一些示例代码，用于从文件中提取所有注释(未经测试，但足以使您入门):

Here's some example code to get all comments out of a file (it's untested, but should be enough to get you started):

<?php

    $source = file_get_contents( "file.php" );

    $tokens = token_get_all( $source );
    $comment = array(
        T_COMMENT,      // All comments since PHP5
        T_ML_COMMENT,   // Multiline comments PHP4 only
        T_DOC_COMMENT   // PHPDoc comments      
    );
    foreach( $tokens as $token ) {
        if( !in_array($token[0], $comment) )
            continue;
        // Do something with the comment
        $txt = $token[1];
    }

?>
