  8. PHP • Pre-Hypertext Processor • The programming language (logic) • Non-Compiled • Stand Alone or imbedded in HTML • All PHP files must end in .php

  9. PHP and RPG • Both are easy to use for business logic • Both are procedural languages • Both can access iseries objects • Both run on the iseries • Both benefit from short acronyms

  11. PHP example <?php echo “Hello World”; ?> <?php $variable = “Hello World”; echo $variable; ?>

  12. PHP + HTML example <html> <head> <title>PHP + HTML example</title> </head> <body> <?php $variable = “Hello World!!!” ?> <p><?php echo $variable ?></p> <?php $variable = “Part 2” ?> <p><?php echo $variable ?></p> </body> </html>

  13. PHP conditionals • If($x == 2){ echo “x is equal to 2”; } • while($x < 3){ echo $x; $x++; } • foreach($array as $x){ echo $x; } • do{ echo $x; $x++; } while($x <= 10); • for… • switch…

  14. Try it out! • Go to your page and try creating and changing variables. • Change a variable from a string to an integer: • $var = “Hello World”; • echo $var; • $var = 501; • echo $var; • Test Paragraphs and line breaks
