如何将php和html文件的内容显示到textarea中？

Question

I am trying to display the content of a file that contains both php code and html code into a textarea. I did

<textarea name='codemodifier' cols='110' rows='35' id='codemodifier' class='form-control' style='height: 75vh;'><?php echo file_get_contents("myfile.php"); ?></textarea>

However instead of it displaying only the content of the file, it displays other html codes under the textarea

I edited my code and did

<textarea name='codemodifier' cols='110' rows='35' id='codemodifier'
class='form-control' style='height: 75vh;'><?php echo
htmlspecialchars(file_get_contents("myfile.php")); ?></textarea>

And then nothing shows anymore in the textarea. I get the same problem when i use htmlentites instead of htmlspecialchars.

Answer 1

Those look like UTF-8 characters, try decoding them using utf_decode() before you output the contents of the file in to the textarea.

This function converts the string data from the UTF-8 encoding to ISO-8859-1. Bytes in the string which are not valid UTF-8, and UTF-8 characters which do not exist in ISO-8859-1 (that is, characters above U+00FF) are replaced with ?.
