DarkWater Posted September 13, 2008 Share Posted September 13, 2008 No, it's not. This is because Apache needs to tell the PHP interpreter to run the code. Link to comment https://forums.phpfreaks.com/topic/124009-learning-php/#findComment-640221 Share on other sites More sharing options...

DarkWater Posted September 13, 2008 Share Posted September 13, 2008 i understand now..i've just finished college and plan on doing web design and just trying to learn everything through online videos. the help is much appreciated thanks You'll find a lot more information in tutorials and books. One piece of advice though: Don't copy tutorials code for code. Then you have no idea what you just did. Use tutorials to introduce new concepts, not copy from.

j05hr Posted September 13, 2008 Author Share Posted September 13, 2008 learning about variables now and stumbled across an error. i copied the code letter for letter from the code but mine comes up with an error. here's my code <html> <head> <title>Variables</title> <head> <body> <?PHP $var1 = 10; echo $var1; $my_variable = "hello world"; $my_Variable = "hello world again"; echo $my_variable echo "br />"; $var1 = 100 echo $var1; ?> </body> </html> and this is the error message Parse error: syntax error, unexpected T_ECHO, expecting ',' or ';' in C:\wamp\www\php_sandbox\variables1.php on line 12 my code is exactly the same as the other persons so i cant see what's wrong Link to comment https://forums.phpfreaks.com/topic/124009-learning-php/#findComment-640260 Share on other sites More sharing options...
DarkWater Posted September 13, 2008 Share Posted September 13, 2008 You missed a ; after "echo $my_variable". Also, I may just be nitpicking, but make the opening PHP tag lowercase. Uppercase just seems so weird. Link to comment https://forums.phpfreaks.com/topic/124009-learning-php/#findComment-640262 Share on other sites More sharing options...
j05hr Posted September 13, 2008 Author Share Posted September 13, 2008 i corrected that now but it didn't fix it, i'm now getting an error code saying Parse error: syntax error, unexpected T_ECHO in C:\wamp\www\php_sandbox\variables1.php on line 14 i may be wrong but i think its something to do with duplicating the $var1 because when i take that out it works fine and as for the php being in uppercase i'm a complete noob so all constructive criticism is welcome Link to comment https://forums.phpfreaks.com/topic/124009-learning-php/#findComment-640263 Share on other sites More sharing options...
DarkWater Posted September 13, 2008 Share Posted September 13, 2008 You missed another ; after "$var1 = 100". Semicolons go at the end of basically ever line of code (except for certain things like loops).

ratcateme Posted September 17, 2008 Share Posted September 17, 2008 you need to escape double quotes in a string that is defined inside double quotes so this echo "<ul class=\ "pages">"; becomes echo "<ul class=\ \"pages\">"; Scott.
