Operators in PHP

Operators in PHP

Operator is a symbol which is used to perform mathematical and logical operations in the programing languages. Different types of operator in PHP are:

1. Arithmetic operators,

2. Assignment operators,

3. Comparison operators,

4. Increment/Decrement operators,

5. Logical operators, and

6. String operators.

1. Arithmetic operators

The arithmetic operators in PHP perform general arithmetical operations, such as addition, subtraction, multiplication and division etc. Refer Table 4.1.

2. Assignment Operators:

Assignment operators are performed with numeric values to store a value to a variable. The default assignment operator is “=”. This operator sets the left side operant value of expression to right side variable. Refer Table 4.2.

3. Comparison Operators:

Comparison operators perform an action to compare two values. These values may contain integer or string data types (Number or Strings). Refer Table 4.3.

4. Increment and Decrement Operators:

Increment and decrement operators are used to perform the task of increasing or decreasing variable’s value. This operator is mostly used during iterations in the program logics. Refer Table 4.4.

5. Logical Operators:

Logical Operators are used to combine conditional statements. Refer Table 4.5.

6. String Operators:

Two operators are used to perform string related operations such as Concatenation and Concatenation assignment (Appends). Refer Table 4.6.
