In PHP there are many ways to do the same thing. (Perhaps not such a good idea…). For fun, I would like to see how many ways we can come up with to output the basic Hello World phrase. I am guessing we could come up with at least a hundred. I will start with the two most obvious ones and contribute more when the list gets going.

1.[php]\<?php  
echo “Hello World”;  
?\>[/php]

2.[php]\<?php  
print “Hello World”;  
?\>[/php]

[member=46186]Kevin Rubio[/member] still, the loop is unnecessary

[php]\<?php  
$a = range(‘d’, ‘w’);  
echo ucwords("$a[4]$a[1]$a[8]$a[8]$a[11] $a[19]$a[11]$a[14]$a[8]$a[0]!");[/php]
