Bug #79500 [NEW]: Duplicate function execution due to an HTML error
From: dev at vraq dot fr
Operating system: All
PHP version: 7.4.5
Package: Unknown/Other Function
Bug Type: Bug
Bug description:Duplicate function execution due to an HTML error
Description:
------------
(Sorry if my English isn't always correct, I'm still struggling with the
language (and I'm using DeepL to help me))
Version of PHP where the bug was found: 7.4, 7.3, 7.2 (WAMP et
Infomaniak)
For some reason, this bug occurs when there is an HTML tag containing an
empty background-url style attribute :
<div style="background-image: url('');"></div>
This line generates, depending on the content of the defined function, a
double execution of the function.
Test script:
---------------
I made a small demonstration of the bug in a few lines:
https://test.vraq.fr/php_css_bug/
Expected result:
----------------
An entry must be present in the log file when the page is loaded.
Actual result:
--------------
Two entries were made in the file as if the function had been executed
twice.
I have the same problem with a mail function. Conversely, if you put an
ECHO in the function, it will be displayed only once.
