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.

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

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
