\nWelcome to part 3 of my 10 part series on PHP. In the first
\ntwo parts I introduced you to the language and to what
\nsoftware you needed to run it.\n<\/div>\n
\nIn this episode we will look at some simple PHP syntax, and
\nwe’ll write a couple of small scripts to get our feet wet,
\nand get a feel for the language.\n<\/div>\n
\nWhat does a PHP script look like?\n<\/div>\n
\nPHP traditionally is embedded into HTML code within a web
\npage, as this was its initial intent. However it’s becoming
\nincreasingly more popular for web application authors to
\nwrite and generate the HTML using PHP from a page that is
\nmade entirely of PHP code.\n<\/div>\n
\nThe following two examples of the world renowned hello world
\nprogram should help to show the difference:\n<\/div>\n
\nEmbedding in HTML\n<\/div>\n
\n<html>\n  <head>\n    <title><?php print \"My First Script\"; ?><\/title>\n  <\/head>\n  <body>\n    <?php\n        \n        print \"<h1>Hello World<\/h1>\";\n\n      ?>\n    <\/body>\n  <\/html>\n<\/pre>\n
\nFull PHP\n<\/div>\n
\n<\/p>\n
\u00a0\u00a0<?php<\/p>\n
\u00a0\u00a0\u00a0\u00a0$content\u00a0<\/span>=\u00a0<\/span>\"<html>nt<head>ntt<title>\"<\/span>;
\n
\u00a0\u00a0\u00a0\u00a0<\/span>$content\u00a0<\/span>.=\u00a0<\/span>\"My\u00a0First\u00a0Script\"<\/span>;
\n
\u00a0\u00a0\u00a0\u00a0<\/span>$content\u00a0<\/span>.=\u00a0<\/span>\"<\/title>nt<\/head>n\"<\/span>;
\n
\u00a0\u00a0\u00a0\u00a0<\/span>$content\u00a0<\/span>.=\u00a0<\/span>\"t<body>nt<h1>\"<\/span>;
\n
\u00a0\u00a0\u00a0\u00a0<\/span>$content\u00a0<\/span>.=\u00a0<\/span>\"Hello\u00a0World\"<\/span>;
\n
\u00a0\u00a0\u00a0\u00a0<\/span>$content\u00a0<\/span>.=\u00a0<\/span>\"<\/h1>n<\/body>n<\/html>\"<\/span>;<\/p>\n
\u00a0\u00a0\u00a0\u00a0print\u00a0<\/span>$content<\/span>;<\/p>\n
\u00a0\u00a0<\/span>?>
\n
<\/span>
\n<\/span>
\n<\/code><\/font><\/div>\n

\nEdited for correctness
\n<\/b><\/p>\n
\nWhen run using your web server set up, both scripts will
\nproduce the following:\n<\/div>\n
\n<\/p>\n
\n  <html>\n    <head>\n      <title>My First Script<\/title>\n    <\/head>\n    <body>\n      <h1>Hello World<\/h1>\n    <\/body>\n  <\/html>\n<\/pre>\n
    <\/code>\n    <\/div>\n
\nMy personal preference is embedding the PHP code within the
\nHTML code, however there are plenty of alternative theories
\nout there, and I would encourage you to explore and develop
\nyour own style of writing scripts.\n<\/div>\n
\nAs an example if you ever decide to work with the Typo3
\nframework (http:\/\/www.typo3.org\/) then you’ll be highly
\nlikely to use the Full PHP approach.  For the remainder of
\nthis series we’ll be using the embedded HTML approach.\n<\/div>\n
\nThe first script line by line\n<\/div>\n
\nAs you can see most PHP statements are included in special
\nPHP tags which for the most part are no different to regular
\nHTML tags.\n<\/div>\n
\nBecause of this, we can freely use them inter-changeably
\nanywhere you would use any other HTML tags.\n<\/div>\n
\nLooking at the title line in the first example above, you
\ncan see that we generate the title using PHP code and a
\nstatic string.  You could use a variable, but since we’re
\nnot covering them until next time I’ll skip over that for
\nnow.\n<\/div>\n<\/div>\n
