[quote author=bodenzord link=topic=99377.msg394950#msg394950 date=1152596732] Okay...the problem was that you had <br /> on line 22 that should not have been there. Check out the corrected code: [code]<!DOCTYPE html PUBLIC "-//W3C// DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml/DTD/xhtml1-strict.dtd"> <html> <head> <title>Listing 4.2 Changing the Type of a variable with settype()</title> </head> </html> <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 " -- $undecided<br />"; // 1 ?> </div> </body> </html>[/code] [/quote] Uhm, when I run bodenzord's modified script, I get this: [code]bash-3.1$ php firstPHPscript-bodenzord.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 4.2 Changing the Type of a variable with settype()</title> </head> </html> <body> <div> double-- 3.14<br />PHP Notice: Use of undefined constant string - assumed 'string' in /home/invert/programming/PHP/firstPHPscript-bodenzord.php on line 15 string-- 3.14<br />PHP Notice: Use of undefined constant int - assumed 'int' in /home/invert/programming/PHP/firstPHPscript-bodenzord.php on line 18 integer -- 3<br />PHP Notice: Use of undefined constant double - assumed 'double' in /home/invert/programming/PHP/firstPHPscript-bodenzord.php on line 21 double -- 3<br />PHP Notice: Use of undefined constant bool - assumed 'bool' in /home/invert/programming/PHP/firstPHPscript-bodenzord.php on line 24 boolean -- 1<br /></div> </body> </html>bash-3.1$ [/code]What's going on here?

Thanks bodenzord for the parenthesis correction. I'm still getting an error for line 22. Here is what my script looks like now: [code]<!DOCTYPE html PUBLIC "-//W3C// DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml/DTD/xhtml1-strict.dtd"> <html> <head> <title>Listing 4.2 Changing the Type of a variable with settype()</title> </head> </html> <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<br />); // double print " -- $undecided<br />"; // 3.0 settype( $undecided, bool ); print gettype( $undecided ); //boolean print " -- $undecided<br />"; // 1 ?> </div> </body> </html>[/code]

[quote author=kenrbnsn link=topic=99377.msg394900#msg394900 date=1152589782] 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: [code]<?php print " -- $undecided<br />; // 1?>[/code] It should be written: [code]<?php print " -- $undecided<br />"; // 1?>[/code][/quote] [quote author=Dville link=topic=99377.msg394875#msg394875 date=1152585537] [code],/div>[/code] should be [code]</div>[/code]Ken [/quote]Thanks for the quick replies. But even with these two corrections, line 22 is still some how problematic.

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/manual/en/language.types.string.php I'll respond to the the posts made by kenrbnsn and Dville soon.

My second script in PHP is a settype exercise. It looks like this:[code]<!DOCTYPE html PUBLIC "-//W3C// DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml/DTD/xhtml1-strict.dtd"> <html> <head> <title>Listing 4.2 Changing the Type of a variable with settype()</title> </head> </html> <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<br />"; // double print " -- $undecided<br />"; // 3.0 settype( $undecided, bool ); print gettype( $undecided ); //boolean print " -- $undecided<br />; // 1 ?> ,/div> </body> </html>[/code] That script produces this error:[code]bash-3.1$ php settypePHPExercise.php PHP Parse error: syntax error, unexpected '>' in /home/invert/programming/settypePHPExercise.php on line 22 bash-3.1$ [/code] I can't figure out what's wrong with my line 22. Can you?

I'm bumping this thread because I significantly edited my last post.

The first PHP script I've written looks like this:[code]<!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( $testing ); // boolean print "<br />"; ?> </div> </body>[/code]When I try to execute it with my bash commandline, I get this error:[code]bash-3.00$ php firstPHPscript.php PHP Parse error: syntax error, unexpected T_PRINT in /home/invert/programming/firstPHPscript.php on line 21[/code] Looking at line 21, I can't spot the mistake I've made. Can you?
