PHP

In a PHP application I was debugging today for a company I found them using ltrim to remove a substring from the start of a string which was producing weird results such as "tal" after invoking with "Total".
When I asked their programmer why is he using ltrim, he replied to strip out a substring from the start of the string....

When using regular expressions with PHP one must take care of a few minute details.
For instance, today I received a request to debug an application.
$patterns[0] = "/^Top/";

Edit the file PAGEFACTORY.php
Add
$this->_jsbutton('blockquote',"blockquoteThis()",_ADD_BLOCKQUOTE_TT ." (Ctrl + Shift + Q)");

From time to time, pages change location. At times like these, one can use PHP header function with 301 redirect to notify website visitors that the page has moved, assuming the $location contains the new URL.
Here is how you can use PHP header 301 redirect...
