Browsers send to the server information about there operating environment for every user that accesses your web page. PHP stores this information in its $_SERVER global variable. NewChk can output this information with one call.


This output came from this call:

new chk($_SERVER);

Let’s go over the output.

The first line says $_SERVER is an array, and new chk($_SERVER) was called in the inventorysave.php file on line 32.

The rest of the lines show you each of the $_SERVER variables with the variable name on the left, and the value of the variable on the right.
