The first PHP script I've written looks like this:
<!DOCTYPE html PUBLIC
   "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http:www.w3.org/TR/xhtml/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Listing 4.1 Testing the tpe of varibable</title>
</head>
<body>
<div>
<?php
$testing; // declare without assigning
print gettype ($testing ); //NULL
print "<br />";
$testing = 5;
print gettype( $testing ); //integer
print "<br />";
$testing = "five";
print gettype( $testing ); // string
print "<br />";
$testing = 5.0
print gettype( $testing ); // double
print "<br />";
$testing = true;
print gettype( $testing ); // boolean
print "<br />";
?>
</div>
</body>
When I try to execute it with my bash commandline, I get this error:
bash-3.00$ php firstPHPscript.php
PHP Parse error:  syntax error, unexpected T_PRINT in /home/invert/programming/firstPHPscript.php on line 21
Looking at line 21, I can't spot the mistake I've made.  Can you?

Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)

Thanks Crayon for the quick response.  WIth your correction, the script now executes with different errors:
bash-3.00$ php firstPHPscript.php       
<!DOCTYPE html PUBLIC
   "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http:www.w3.org/TR/xhtml/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Listing 4.1 Testing the tpe of varibable</title>
</head>
<body>
<div>
PHP Notice:  Undefined variable:  testing in /home/invert/programming/firstPHPscript.php on line 11
PHP Notice:  Undefined variable:  testing in /home/invert/programming/firstPHPscript.php on line 12
NULL<br />integer<br />string<br />double<br />boolean<br /></div>
</body>
And here is how my script renders in firefox:
"; $testing = 5; print gettype( $testing ); //integer print "
"; $testing = "five"; print gettype( $testing ); // string print "
"; $testing = 5.0; print gettype( $testing ); // double print "
"; $testing = true; print gettype( $testing ); // boolean print "
"; ?>

umm... are you running your script on your own computer? if so, then you have to install php in order to run php files on your computer.

My second script in PHP is a settype exercise.  It looks like this:

That script produces this error:
bash-3.1$ php settypePHPExercise.php
PHP Parse error:  syntax error, unexpected '>' in /home/invert/programming/settypePHPExercise.php on line 22
bash-3.1$
I can't figure out what's wrong with my line 22. Can you?

Yes, the </div> tag is incorrect, but PHP shouldn't be complaining about it. What's really wrong is that you forgot the terminating double quote on this line:
<?php print " -- $undecided<br />; // 1?>
It should be written:
<?php print " -- $undecided<br />"; // 1?>

According to itrebal on freenode, “well $testing; doesn't declare the variable - you avhe to actually set it to something.”  Further, “you cant output HTML with the variable like that.” I didn’t really know what itrebal was talking about so I asked him, “wtf?”  itrebal recommended http://ca3.php.net/strings and http://us3.php.net/m...ypes.string.php

I'll respond to the the posts made by kenrbnsn and Dville soon.

Thanks for the quick replies.  But even with these two corrections, line 22 is still some how problematic.

This following line is incorrect:

print gettype( $undecided<br />"; // double

Change it to:

print gettype( $undecided<br />); // double

Notice that you have a quote at the end just before the semi-colon that is supposed to be a closing parenthesis.

Thanks bodenzord for the parenthesis correction.  I'm still getting an error for line 22.  Here is what my script looks like now:

print "-- $undecided<br />"; //3.14

Okay...the problem was that you had <br /> on line 22 that should not have been there. Check out the corrected code:

<!DOCTYPE html PUBLIC

"http://www.w3.org/TR/xhtml/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Listing 4.2 Changing the Type of a variable with settype()</title>

<body>
<div>
<?php
$undecided = 3.14;
print gettype( $undecided ); // double
print "-- $undecided<br />"; //3.14
settype( $undecided, string );
print gettype( $undecided ); // string
print "-- $undecided<br />"; //3.14
settype( $undecided, int );
print gettype( $undecided ); // integer
print " -- $undecided<br />"; // 3
settype( $undecided, double );
print gettype( $undecided); // double
print " -- $undecided<br />"; // 3.0
settype( $undecided, bool );
print gettype( $undecided ); //boolean
print " -- $undecided<br />"; // 1
?>
</div>

Uhm, when I run bodenzord's modified script, I get this:

bash-3.1$ php firstPHPscript-bodenzord.php

What's going on here? What am I doing wrong?

<?php
$testing; // declare without assigning
print gettype ($testing ); //NULL
print "<br />";
$testing = 5;
print gettype( $testing ); //integer
print "<br />";
$testing = "five";
print gettype( $testing ); // string
print "<br />";
$testing = 5.0
print gettype( $testing ); // double
print "<br />";
$testing = true;
print gettype( $testing ); // boolean
print "<br />";
?>

print sucks for one, use echo.. for 2, you forgot a semicolon, 3, all that unneeded whitespace adds to your filesize, get rid of it..

<?php
$testing = ""; // declare without assigning
echo gettype($testing); //NULL
echo "<br>";
$testing = 5;
echo gettype($testing); //integer
echo "<br>";
$testing = "five";
echo gettype($testing); // string
echo "<br>";
$testing = 5.0;
echo gettype($testing); // double
echo "<br>";
$testing = true;
echo gettype($testing); // boolean
echo "<br>";
/* returns:
string<br>integer<br>string<br>double<br>boolean<br>
*/
?>
