Description:
------------
PHP 7.3.17-1+0~20200419.57+debian9~1.gbp0fda17 
Linux debian 4.9.0-12-amd64 #1 SMP Debian 4.9.210-1 (2020-01-20) x86_64 GNU/Linux -> On VirtualBox (Host Win7) using Shared Directories.


I am not 100% sure why this error happens:
I use the following code to dump an array to a file (its something like a cache system):

file_put_contents($_SERVER['BASE_DIR'].'website/siteconfig/'.$row['domain'].'.php', '<?php'.PHP_EOL.'$CONFIG = ' . $save . ';', LOCK_EX);

the result looks like:

-----------
<?php
$CONFIG = array (
  'id' => '1',
  'created' => '2020-05-25 00:00:41',
  'lastupdate' => '2020-05-25 17:46:16',
  'tmpl_id' => '1',
  'showperpage' => '18',
  'phrases' => '0',
  'hashtags' => '1',
  'maxpages' => 2,
);
-----------

and the error on including using require():

Parse error: syntax error, unexpected ')', expecting end of file in /srv/myproject/website/siteconfig/testsite.local.php on line 11

Line 11 is: );

=================
This error does not appear every time when i update the testsite.local.php using var_dump. Sometimes it happens, sometimes not.

If this error happens i have to delete the file manually and then execute my var_dump again. Then it is working again. If i update without to delete the old file, the same error stay.

Maybe its some problem with the OPcache?

Note that flocks are advisory locks, so the read operation must also acquire a shared lock. Obviously include does not do that, so it may see partially written files. What you likely want is an atomic rename.
