php file_get_contents（）转换html实体，如＆ouml; 到ö

Question

I try to display the contents of a php file in a textarea with

<textarea ...>
<?php echo file_get_contents("file.php"); ?>
</textarea>

but it converts the html entities like ö to ö. As it is php code I can not use a conversion like htmlspecialchars because it would brick the <> and quotes etc.

EDIT:

I checked the sourcecode with the browser and there is really an ö.

Please help, thank you!

Answer 1

htmlspecialchars will change:

< &ouml;

to:

< ö

and it's ok.

It will display in textarea:

< &ouml;

After you submit form, it will send to server text

< &ouml;

not:

< ö

Tested in Chrome with jQuery:

$('#layout').html('<form method="POST"><textarea name="x">&lt;&amp;ouml;</textarea><input type="submit" /></form>')
