[SOLVED] : parse error, expecting

[Danny620]

all i get when i run this is

 

Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING' in C:\xampp\htdocs\math\edit_user.php on line 120 what does this error mean.

the issue is in your use of array items in double-quoted strings. PHP is expecting a simple variable when you interpolate, and an array item's notation will throw it off. in order to incorporate them, this:

 

   echo "Strand: $row['strand']";
   echo "Score: $row['score']"; 
   echo "attempts: $row['2']";

 

should be:

 

   echo "Strand: {$row['strand']}";
   echo "Score: {$row['score']}"; 
   echo "attempts: {$row['2']}";

 

EDIT: to help you avoid this in future, a parse error of "expecting" something means that PHP came across incorrect syntax usually. look around for unpaired braces, parentheses, brackets, and also check for semicolons.
