How I can check does my CentOS setup have this:

JSON
XML Parsing
MB Strings Module
ZLIB Compression Module
ZIP Handling Module
PCRE Library
IMAP Module
cURL Module
Sprite Support 

I run this commands:

yum install php-gd php-imap php-ldap php-odbc php-mbstring php-pear php-xml php-xmlrpc php-soap
yum install curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel

Is this enough or I need something else to install?

I have LAMP, PHP 5.3.3
