Variables

In PHP, there is no need to explicitly declare variables to reserve memory space. When you assign a value to a variable, declaration happens automatically. Variables are case-sensitive in PHP.

Loops

1. IF Family:

If, If-else, Nested-Ifs are used when you want to perform a certain set of operations based on conditional expressions.

If

If-else

Nested-If-else

2. Switch:

Switch is used to execute one set of statement from multiple conditions.

3. For:

For loop is used to iterate a set of statements based on a condition.

For-each:

4. While:

While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.

5. Do-While:

Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.

Functions

Function is a sub-routine which contains set of statements. Usually functions are written when multiple calls are required to same set of statements which increases re-usuability and modularity.
