Write a php script that will accept a positive integer, if it is even, divide it by 2 and if it is
odd, multiply it by 3 and add 1. Repeat the process until the value is 1, printing out each value.
Finally print out how many of these operations you performed. If the input value is less than 1,
print error and perform an exit(); For example: Initial value: 9 Next value: 28 Next value: 14
Next value: 7 Next value: 22 Next value: 11 Next value: 34 Next value: 17 Next value: 52 Next
value: 26 Next value: 13 Next value: 40 Next value: 20 Next value: 10 Next value: 5 Nex...

I'm trying to validate a user's desired username for a registration page. I want to detect
any illegal characters being used for a username. So far i have managed to include most execpt the
'\', the '\' is used for escape and treating the preceding characters
literally. I try to do '\\' but i get an error because it execects another
character. CODE $ck_result = "Default"; $pattern =
"/[!|@|#|$|%|^|&|*|(|)|_|\-|=|+|\||,|.|\/|;|:|\'

In php coding, when you escape certain characters, they have an impact on the output of an
echo'd or printed string. ie "\r\n\t" should give you a new line and a tab before
outputting the content for a line of printing. They vary by OS, I know, but I have tried all the
variations I can think of and can't seem to control output using them. Believe me, I have tried
multiple variations and nothing works for me. I have checked the php.ini file for settings but I
can't find where you can modify them. So the question is : Where do i look to conf...

Say I have a variable such as $nav_item and it had to contents Home . IE: CODE
$nav_item = 'Home'; How would I make so that $nav_item was an array and
had the following contents? CODE $nav_item = array ('h', 'o',
'm', 'e'); With the case changing (ie H would become h and U
would become u ) EDIT: Okay found out that I could change the case with
array_change_key_case ($nav_item, CASE_LOWER); ...

I am currently making a code for my phpBB forum, where it will import the latest topics from a
specific forum, and display it on the news section of my main page. But the width of that news
section is very tiny, so I want the code to limit the numbers of characters to 25. So, let's
say this is the full title: "This is the title which is a little too long so it needs to be
shortened." This is what I want to show: "This is the title which ..." How can I do that?...
