And the error in the lectura.php file is the following:
Parse error: Invalid body indentation level (expecting an indentation level of at least 4) in C:\xampp\htdocs\utilidades\chat\lectura.php on line 12
And finally, the error in the index.php file is that the messages doesn't appear in the table. I did a xhr many times and tried to print "Hello world" into the chart and printed, but the xhr doesn't print because the URL is blocked or something...

but the xhr doesn't print because the URL is blocked or something...

The problem is not XAMPP, it's your code. Especially the closings of your heredoc parts.

Read more about the proper indention of flexible heredoc syntax here: https://wiki.php.net/rfc/flexible_hered ... c_syntaxes

Thanks!!! But I already fixed it at: https://laboratory-of-drfrank.p.tnnl.in/utilidades/chat/ Sorry.
