Arrays
An array holds multiple values in one variable. Indexed arrays use numbers ($subjects = ["HTML", "CSS", "PHP"]), while associative arrays use named keys ($student = ["name" => "Ali", "age" => 20]). foreach loops through every item in an array automatically.
Why this matters
- ·Stores related data (like a list of subjects) in one place
- ·foreach removes the need to manually track an index
Common mistakes
- ·Accessing an index that doesn't exist gives a warning, not an error you can easily miss
- ·Mixing up array keys ($student["name"]) with numeric indexes causes confusion
HTML CSS PHP
PHP runs on a server, not in the browser this shows the expected output instead of a live one.
