String Operators are used to modify strings.At the bottom of this page there is a code editor pre-loaded with the lesson's code.
// Define variable $gameDev = "Scott"; // Add to the variable $gameDev .= " Cawthon"; // Print the variable echo $gameDev;
$gameDev = "Scott";
$gameDev .= " Cawthon";
Output: Scott Cawthon
// Define $character $character = "Character: "; // Define $chosenCar $chosenChar = $Character . "Freddy"; // Print the message echo $chosenChar;
$character = "Character: ";
$character is a variable containing a string value. The value of $character is "Character: "
$chosenChar = $character. "Freddy";
$chosenChar is a string variable. It's value is equal to $CHARACTER plus "Freddy"
This will print the value of $chosenCar
Output: Character: Freddy
PHP_EOL will insert a line break
// Define variables $numStars = "5";
$gameTitle = "FNAF World"; // Print echo $gameTitle.PHP_EOL; echo "gets $numStars stars!";
$numStars = "5";
$numStars is a variable containing an integer value. It is intialized at 5.
$gameTitle = "FNAF World";
$gameTitle is a string variable intialized at "FNAF World"
will print the value of $gameTitle and insert a line break.
echo "gets $numStars stars!";
will print "gets", the value of $numStars, then "stars!"
Output: FNAF World
gets 5 stars!
You live on post apocalyptic Earth. Aliens called "Bugs" have taken over the planet. As a resistance figher, and web developer, your job is to code warning messages.
Read each description. Use PHP to print the appropriate warning message.
Variables used for messages:
// Number of bugs in the settlement $bugsDetected = 0; // Number of shots fired $shotsFired = 0; // Number of bombs detected $bombsDetected = 0; // string variable containing any weather alters $weather = "";
There are currently 5 bugs detected in the settlement. No shots have been fired. One bomb is detected.
// Define variables $bugsDetected = 5; $shotsFired = 0; $bombsDetected = 1; // Create Message $alert = "There have been $bugsDetected bugs detected in our settlement. "; $alert .= "$shotsFired shots have been fired. "; $alert .= "$bombsDetected bombs have been detected in our settlement."; // Print Message echo $alert;
1) There are 10 bugs detected in the settlement. No shots have been fired. Two bombs are detected. There is a 90% chance of severe thunder storms.
2) There are 10 bugs dectected. 5 shots fired. 2 bombs detected.
3) There are no bugs, shots or bombs detected. There is a hurricane warning. This category 3 hurricane is projected to hit land tomorrow at 3pm.
Once you finish the assignment, play around with variable values and your echo statements in the code editor box below.
