How to check the status of server/host using PHP ?

Recently I came across this trivial problem of checking whether a server is ONLINE or OFFLINE. I tried "Ping" command but the following approach was more elegant.



$host = "127.0.0.1"; // could be any host address 
$port = "80"; //  port you wanna check 

$fp = @fsockopen($host, $port, $errno, $errstr, 2);

if (!$fp) {
echo "DEAD";
} 

else { 
echo "ALIVE";
}

?>

Have fun !

C/C++ on Windows 7 using Eclipse

If you got a "Launch Failed. Binary Not Found" error while running C/C++ project in Eclipse on a Windows 7 machine then you are not the only one. I came across similar problem and I have tried my best to give a terse solution. The reason for this issue might be because  Eclipse doesn't understand the 64 bit binaries generated by our Windows 7 Though,  I'm not sure. Okay, back to our problem. 

The quick steps that are to be followed to run a C/C++ program on Windows 7 are: 

1. We need compiler for Windows for this we are going to install  the following:

(a) MinGW installer

Open exe->Choose download and install-> install Current package->Check MinGW tools, g++ compiler, MinGW make-->install path C:\MinGW->Finish. 

(b) Minsys 

Open downloaded exe-> folder C:\msys\1.0-->For MinGW path give C:\MinGW-> Finish.

2. We set the Path (Environment variables) for these compilers: 

Append following to your Path variables (*can be located in the Advanced tab of System in the control panel under the Environment Variables option - Google it if you still can't locate it)

;C:\msys\1.0\bin;C:\mingw\bin

3. Installing CDT plugin to your existing Eclipse: 

Software Update link is: http://download.eclipse.org/tools/cdt/releases/galileo

4. Create a new  project and run the Helloworld file. 

Done ! 

Post any queries you might have. 

Enjoy!!!
