On Mac OSX Mavericks using homebrew php55 whenever I run a a php command I get the following error message (everything runs fine it\'s just annoying)
PHP War
To fix this problem, you must edit your php.ini (or extensions.ini) file and comment-out the extensions that are already compiled-in. For example, after editing, your ini file may look like the lines below:
;extension=pcre.so ;extension=spl.so
