Operator in PHP

In PHP, operators are symbols that perform operations on variables and values. PHP supports various types of operators, including arithmetic operators, assignment operators, comparison operators, logical operators, and more. Here's a brief overview of some common PHP operators:

  1. Arithmetic Operators:

    • Addition (+)
    • Subtraction (-)
    • Multiplication (*)
    • Division (/)
    • Modulus (%)
    • Increment (++)
    • Decrement (--)

  2. Assignment Operators:

    • Assignment (=)
    • Addition assignment (+=)
    • Subtraction assignment (-=)
    • Multiplication assignment (*=)
    • Division assignment (/=)
    • Modulus assignment (%=)

  3. Comparison Operators:

    • Equal to (==)
    • Identical to (===)
    • Not equal to (!= or <>)
    • Not identical to (!==)
    • Greater than (>)
    • Less than (<)
    • Greater than or equal to (>=)
    • Less than or equal to (<=)

  4. Logical Operators:

    • And (&& or and)
    • Or (|| or or)
    • Not (!)

  5. String Operators:

    • Concatenation (.)

  6. Array Operators:

    • Union (+)
    • Equality (==)
    • Identity (===)
    • Inequality (!= or <>)
    • Non-identity (!==)

  7. Conditional (Ternary) Operator:

    • Ternary operator (expr1 ? expr2 : expr3)

  8. Type Operators:

    • Type of (typeof)
    • Instance of (instanceof)

These operators are used extensively in PHP programming to perform various tasks such as arithmetic calculations, variable assignment, comparisons, logical operations, string manipulation, and more. Understanding how to use operators effectively is essential for writing efficient and concise PHP code.
