The initial game state is "waiting to start," 1 Hi I'm working on a page switch code, the default page does not seem to load for some reason can anyone help at the moment I can enter a random URL but it just shows page not found. That's the natural flow of the game states. "waiting to start," "playing" and "dead." It's actually logical to present the game states ( switch cases) I would put the mindboggling code sent to me by my friend to the Just be prepared that your code might be initially rather confusing to other developers. This way anyone familiar with switch statementsĬan more easily understand the structure of your switch statement. It's safest to put the default case to the end. ![]() PREAMBLE: state can have 3 possible values: 1) 0 (zero, int) 2) 'Set Level: 10 ' (string) 3) 'Set Level: 20 ' (string) I have a switch code that doesn't return right value. Unless you have a good reason to do otherwise, 1 This question already has answers here : Why does PHP consider 0 to be equal to a string (9 answers) Closed 5 years ago. This is simply the logic others have presented to me in the past.") So, should you use non-last default cases? ![]() The value matches no case statements in the switch block."Ĭaused by placing the default case to the top "This means default will run if, and only if, To accidentally fall through to the default case. Void Update ( ) Preventing accidental fallthroughs to the default case That he had copy-pasted picked up from a course The default case has been the last or almost last one. Just remember that if you are going to evaluate a single variable with multiple outcomes use a Switch Statement instead of an If Else Statement.If you think about all the switch statements you have ever seen in your life, ![]() You also learned about case sensitivity issues. This tutorial covered the Switch Statement, how to use operators as well as the keywords used. Just remember when comparing something in different cases you’ll have to force the case to either upper or lower lower is probably best as most people do not normally type in upper case. This will only work if the case labels are lower case, so make sure when you type the labels they are lower case and not upper. This will force the value in $food to be all lower case. We can solve this issue by using the strtolower function. This will output “I don’t know”, because although pasta is one of the case labels it is in a different case. ![]() The default keyword is the default result given if nothing matches the condition, and it goes at the end of the case labels.Īt times you might collect user data and loop through the results, but the cases may differ which could affect the results. For example, take this: $food = "Pasta" If you remove the break keyword from the Switch Statement, you will see the rest of the results echo out. The break keyword in the Switch Statement prevents the Switch Statement from looping through rest of the code. This code will look like this in an If Else Statement since they are so similar: Īs you can see, the Switch Statement is clearer to read and easier to manage if you want to change the variable name. If a switch is inside a loop, continue 2 will continue with the next iteration of the outer loop. continue behaves like break (when no arguments are passed) but will raise a warning as this is likely to be a mistake. Make a new variable called num and give it the value 1. Note: In PHP the switch statement is considered a looping structure for the purposes of continue. ![]()
