Hello Nick,

I didn't give feedback yet, but your answer was fine, it works. I can get the messages of PHP in the messages tab.
Unfortunately Geany does not recognize them. A typical example is :

Parse error: syntax error, unexpected T_VARIABLE in E:\Mes documents\en cours\gui\eclipse PDT\ad-libros\sans titre.php on line 15

I have not yet tried the suggestion about regex. But the main point was having the messages, and it works, thanks.

The messages tab is currently only used for find usage/find in files.

You might be able to do it by setting the Compile command in the
'Build->Set Includes & Arguments' to:
php "%f"

Then when running Build->Compile, Geany will pipe output from PHP back
to the Compiler window. If the runtime PHP messages are like the PHP
compile messages, Geany will highlight them and you can click on them.
If not you could try using a filetype error regex, check the manual for
details.

Regards,
Nick
