Close issue #7 - duplicate PHP errors

[fidian]

Test PHP file: <?php blah(;

php -l test.php works as expected. When you use php -l -d display_errors=1, the warnings get duplicated.

[tomtom]

The display_errors flag was included by artnez (https://github.com/tomtom/checksyntax_vim/commit/a55196c6a866f3710c8a073b6d3dae4c2a28fc93). I don't know the reasons why he added this command line option -- it seems to be the default value for php < 5.2.4 anyway. From what I gather, it causes php to print error messages on stdout. I don't have php accessible, are the error messages also printed on stderr?

It seems the value for this option has changed. Does the problem persist if you run php -l -d display_errors=stdout (php >= 5.2.4)?

[fidian]

Yes, they persist, and yes, they are on both stdout and stderr.

I think this explains that behaviour: http://stackoverflow.com/questions/10771959/unexpected-error-reporting-behavior-in-cli-binary

[fidian]

In light of the page you found, perhaps you should also add "-d error_log=" (i.e. set error_log to an empty value) so that the messages are never doubled, no matter what type of installation you have?
