Solve the problem that the php page is blank after centos6.5 yum is installed with lamp

The php page is blank after lamp is installed as follows:

Yum-y install httpd php mysql-server php-mysql httpd-manual mod_ssl mod_perl mod_auth_mysql php-mcrypt php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc mysql-connector-odbc mysql-devel libdbi-dbd-mysql

However, the test page can be displayed normally. I don't know why. Thank you.
<? Php phpinfo ();?>

Solution:
Vi/etc/php. ini
Change short_open_tag = Off TO short_open_tag = On.

Restart the httpd service and refresh the browser to access it!
