Useful Information about PHP
Hi friends, Below things are very useful when we develop websites using php code. We most know about these things.
1) To check pear package is installed in your server or not.
Note : It will give information about pear package in our server.
When i was working in website, in that website php code is written in a static htm file. For that we just put a one line code in a .htaccess file, it will work.
3) To display warnings in php file
After hosting files into a new server, it does not give output, it shows empty page, because that files contains warnings. In a server default warnings are disable, to enable those warnings add below code in a starting of php file.
4) Warning : header already sent or cannot modify header information
This warning mainly occurs when there is white space before the header location or some echo statements before the header location. So better prevent echo and white spaces before the header statement this warning will prevented.
