file_put_contents将错误的字符保存到文件中

Question

I have saved some contents (PHPdoc block) to a file using file_put_contents, but, when that file get read by another program, it does not read my phpdoc text. But when I save (add a space and remove it) the file in Netbeans IDE, the other program can read the phpdoc block without having to fix anything. What could be the cause and how to fix it.

There is no error in the generated text. I just saved the file using Netbeans and it worked, I did not modify anythinng.

The code:

                $tableOrmAnnotation = "* @ORM\\Table(name=\"song\")";
                $evntHandlerCode = "* @ORM\\EntityListeners({\"hghcgh\\gvhghgBundle\\EventListener\\SongUploadListener\"})";

                $entityCnt = file_get_contents($entityFilePath);

                $entityCnt = \str_replace($tableOrmAnnotation, $tableOrmAnnotation . "
 " . $evntHandlerCode, $entityCnt);

                \file_put_contents($entityFilePath, $entityCnt);

The generated text:

/**
 * Song
 *
 * @ORM\Table(name="song")
 * @ORM\EntityListeners({"hghcgh\gvhghgBundle\EventListener\SongUploadListener"})
 * @ORM\Entity(repositoryClass="hghcgh\gvhghgBundle\Repository\SongRepository")
 */
class Song

Answer 1

It wasn't any character problem. It was a cache problem. As my project is a Symfony Project and the file I had edited was generated first by Symfony, it cached the annotations(phpdoc) and ignore my following modifications. Then when I launch the project, Symfony read the cache not the entity file. So when I edit the file manually or delete the cache, Symfony regenerates the annotations cache (looks like Symfony reads the file modification date).
