Operator Types - PHP

Operator:

The Operator is a expression like as we can say 5+7 equal to 12. So Here we will say 5 and 7 operands and + is a operator.
Advance PHP Language follow different types of Operators. These are following...

  • Comparison Operators
  • Arithmetic Operators
  • Logical (Relational) Operators
  • Assignment Operators
  • Conditional (Ternary) Operators


Here we will discuss all in detail one by one.

  1. Comparison Operators


We discuss some of comparison operators follow by PHP language

Assume variable One holds 5 and variable Two holds 8 then......

Examples of Comparison operators are.....

Operator Description  Example
  • " == "    (it will Checks when the value of two operands equal or not equal, if yes then condition becomes true.)                          (A == B) is not true.
  • " != "    (it will Checks when the value of two operands equal or not equal, if the values not equal, that's condition becomes true.)  (A != B) is true.
  • " > "    (it will Checks When left operand value is greater than right operand value, if it will yes then condition will true.)              (A > B) is not true.
  • " < "          (it will Checks When left operand value is less than right operand value, if it will yes then condition will true.)                 (A < B) is true.
  • " >= "    (it will Checks when the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.)     (A >= B) is not true.
  • " <= "    (it will Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true.)    (A <= B) is true.

       2:Arithmetic Operators


We will discuss following arithmetic operators that link by PHP language −

Assume variable One holds 3 and variable Two holds 5 then....

Example of Arithmetic Operators are...

  • " + " (It will Adds two different operands)                  A + B will give 8
  • " - "         (Ir will Subtracts 2nd operand from the 1st)           A - B will give -2
  • " * "         (It will Multiply both different operands)           A * B will give 15
  • " / "   (Divide numerator by de-numerator)                   B / A will give 1.66
  • " % " (Modulus Operator and remainder of after an integer division)                                                           B % A will give 0
  • " ++ " (This Operator is Increment operator, increases integer value by one)                                                 A++ will give 4
  • " -- " (This Operator is Decrement operator, decreases integer value by one)                                                 A-- will give 2

Constant Types-PHP

Image
Constant A Constant is an identifier (call) for a Easy value. As the name indicates, that cost Cannot Exchange for the Duration of the Execution of the script (besides for Magic constants, which are not simply constants). A consistent is case-sensitive with the aid of default. With the aid of conference, Constant identifiers are continually Uppercase.  A constant call begins with a letter or underscore, observed via any range of letters, numbers, or underscores. When you have described a Constant, it could in no way be modified or undefined. To outline a constant you need to use outline() function and to retrieve the cost of a regular, you need to really specifying its name. Unlike with variables, you do no longer want to have a Constant with a $. You may additionally use the feature Consistent() to examine a Constant's cost if you want to Achieve the Constant's name dynamically. Constant () function: As indicated by means of the call, this characteristic will retu...

3:Logical Operators We Will Discuss following logical operators that are link by PHP language Assume variable One holds 5 and variable Two holds 10 then... Some of the following Examples of Logical Operators are here.... " And " (it's Called Logical AND operator. If both the operands are true then condition becomes true.)                                     (A and B) is true. " Or " (it's Called Logical OR Operator. If any of the two operands are non-zero then condition becomes true.)                      (A or B) is true. " && " (it's Called Logical AND operator. If both the operands are non-zero then condition becomes true.)                                       (A && B) is true. " || " (it's Called Logic...

Variable Types For PHP

Image
Variable Types The primary Manner to Keep Information within the Middle of a PHP Program is by using the use of a Variable. Here are the maximum vital matters to recognise about variables in PHP(Hypertext Preprocessor). All Variables in PHP(Hypertext Preprocessor) are Denoted with a leading Dollar sign ($). The Value of a Variable is the Cost of its most Current Task. Variables are assigned with the = operator, with the variable at the left-hand facet and the expression to be evaluated on the right. Variables can, but do now not need, to be Declared earlier than Assignment. Variables in Hypertext Preprocessor(PHP) do no longer have intrinsic Sorts - a Variable does now not know earlier whether it'll be used to save more than a few or a String of Characters. Variables used earlier than they're Assigned have Default values. Hypertext PreProcessor(PHP) does a great job of automatically converting types from one to some other while important or Necessary. Hypertext...
