Pre-Module PHP Introduction BTM 395: Internet Programming

PHP • PHP: Hypertext Preprocessor • Originally called “Personal Home Page Tools” • Popular server-side scripting technology • Open-source • Anyone may view, modify and redistribute source code • Supported freely by community • Platform independent

Basic application • Filenames end with .php by convention • Server can be set to recognize other extensions (even .html) • Scripting delimiters • <?php … ?> • Or just <? … ?>, but this form not recommended • Must enclose all script code • Any HTML code outside the <?php … ?> tags will be processed as HTML • Variables preceded by $ symbol • Case-sensitive • Permits easily embedding variables in strings
