That said, there are a few different types of strings and they offer slightly different syntax, with slightly different behaviors.

Single quotes are used to denote a “literal string”.

if you write echo "mytext".$result-- the correct return result would be given by echo "mytext".(--$result) another problem that you noticed was that the Dot (.) operator is not always processed last so braces () become mandatory.

:) you are actually using the direct return value from the decrement function.

Second and most importantly, the value it returns evaluates to true or false, and ultimately determines whether the condition passes. But used well in suitable circumstances, it can simplify many conditions to produce faster and leaner code.

James is a freelance web developer based in the UK, specialising in Java Script application development and building accessible websites. $result-- ; echo ''; and the output is like this: Value now is 8 Add 2, Value now is 10 Subtract 4, Value now is 6 Multiply by 5, Value now is 30 Divide by 3, Value now is 10 Increment by one, Value now is 10 Decrement by one, Value now is 11 Why the value in the last value (increment and decrement by one) is miscalculated? I appreciate all of your effort for helping me, thanks before.. --$v .'.'; this was the result when Value is now 8Add 2. $result ;echo ''; echo 'Decrement by one, Value now is '. Value is now ".$variable.""; $variable /= 3; echo "Divide by 3. Value is now ".$variable.""; $variable ; echo "Increment value by 1. $result -= 4; echo ''; echo 'Multiply by 5, Value now is '. Value is now 8 when I put a variable in a string and updated the variable Gave the following result Value is now 8Add 2. $result =2; echo ''; echo 'Subtract 4, Value now is '. For this PHP exercise, write a script to reproduce the output below. Later on the value in $result is incremented and that's shown while decrement operator is used. Manipulate only one variable using no simple arithmetic operators to produce the values given in the statements. Only after that value in $result will be decremented. "; docommand("Add 2"); docommand("Increment value by 6"); docommand("Decrement value by 8"); docommand("Multilpy value by 10"); docommand("Divide by 5"); docommand("Multiply this $thevalue with $thevalue"); ? Value is now 8 I had some trouble by using the following statement for increment and decrement: print "Increment value by one.
