What is Operator in PHP ?<\/h2>\n

Operator in PHP : An operator<\/b> is a symbol that tells \u00a0to perform specific mathematical or logical functions. In PHP\u00a0there \u00a0are following\u00a0types of operators<\/b><\/p>\n

    \n
  1. Arithmetic Operators<\/li>\n
  2. Comparison Operators<\/li>\n
  3. Logical (or Relational) Operators<\/li>\n
  4. Assignment Operators<\/li>\n
  5. Conditional (or ternary) Operators<\/li>\n<\/ol>\n<\/blockquote>\n

    Arithmetic Operators in PHP:<\/h2>\n

    Arithmetic Operators are those operators which perform Calculation .If we want to perform Mathematical operation then \u00a0Arithmetic Operators are use \u00a0like +,-,*,\/,%,++,–. Generally it is used for calculation between variables.<\/p>\n

    Assume $x and $y \u00a0are two variables <\/a>having value $x=10 ,$y=5, Then the Result will be give by Operators are<\/p>\n\n\n\n\n\n\n\n\n\n\n
    Operator<\/strong><\/td>\nExample<\/strong><\/td>\nResult<\/strong><\/td>\nOperation Performed<\/strong><\/td>\n<\/tr>\n
    +<\/td>\n$x + $y<\/td>\n30<\/td>\nAdds two operands<\/td>\n<\/tr>\n
    –<\/td>\n$x- $y<\/td>\n5<\/td>\nSubtracts second operand from the first<\/td>\n<\/tr>\n
    *<\/td>\n$x* $y<\/td>\n50<\/td>\nMultiply both operands<\/td>\n<\/tr>\n
    \/<\/td>\n$x \/ $y<\/td>\n2<\/td>\nDivide numerator by de-numerator<\/td>\n<\/tr>\n
    %<\/td>\n$x % $y<\/td>\n0<\/td>\nModulus Operator and remainder of after an integer division<\/td>\n<\/tr>\n
    ++<\/td>\n$x++<\/td>\n11<\/td>\nIncrement operator, increases integer value by one<\/td>\n<\/tr>\n
    —<\/td>\n$x–<\/td>\n9<\/td>\nDecrement operator, decreases integer value by ones<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Comparison Operators\u00a0in PHP:<\/h2>\n

    Comparison Operators are those operators which perform Comparison .If we want to perform any\u00a0Comparison operation then Comparison Operators are use \u00a0like ==,!=,<,>,>=,<=. Generally it is used for Comparison between variables or for to check whether the desired value is available or not.<\/p>\n

    Assume $x and $y \u00a0are two variables <\/a>having value $x=10 ,$y=5, Then the Result will be give by Operators are<\/p>\n\n\n\n\n\n\n\n\n\n\n
    Operator<\/strong><\/td>\nExample<\/strong><\/td>\nResult <\/strong><\/td>\nOperation Performed\u00a0<\/strong><\/td>\n<\/tr>\n
    ==<\/td>\n($x == $y)<\/td>\nFalse<\/td>\nIf value of two operands are equal or not, if yes then condition becomes true.<\/td>\n<\/tr>\n
    !=<\/td>\n($x != $y)<\/td>\nTrue<\/td>\nIf value of two operands are equal or not, if values are not equal then condition becomes true.<\/td>\n<\/tr>\n
    ><\/td>\n($x \u00a0> $y)<\/td>\nTrue<\/td>\nIf value of left operand is greater than value of right operand, if yes then condition becomes true.<\/td>\n<\/tr>\n
    <<\/td>\n($x \u00a0< $y)<\/td>\nFalse<\/td>\nIf value of left operand is less than value of right operand, if yes then condition becomes true.<\/td>\n<\/tr>\n
    >=<\/td>\n($x \u00a0>= $y)<\/td>\nTrue<\/td>\nIf value of left operand is greater than or equal to value of right operand, if yes then condition becomes true.<\/td>\n<\/tr>\n
    <=<\/td>\n($x \u00a0<= $y)<\/td>\nFalse<\/td>\nIf value of left operand is less than or equal to value of right operand, if yes then condition becomes true.<\/td>\n<\/tr>\n
    \u00a0===<\/td>\n\u00a0($x===$y)<\/td>\n\u00a0False<\/td>\n\u00a0If value of two operands are equal and the data types <\/a>are same\u00a0, if yes then condition becomes true.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Logical \u00a0Operators\u00a0in PHP:<\/h2>\n

    Logical \u00a0Operators is also called\u00a0Relational Operators. These operator Checks the logic of the condition where the condition goes right or wrong.For example we want to check that give value is according to us then perform first Condition if not then Second condition
    \nAssume $x and $y \u00a0are two\u00a0     variables <\/a> having value $x=10 ,$y=5, Then the Result will be give by Operators are<\/p>\n\n\n\n\n\n\n\n\n
    Operator<\/strong><\/td>\nExample<\/strong><\/td>\nName of Logical Operator<\/strong><\/td>\nOperation Performed\u00a0<\/strong><\/td>\n<\/tr>\n
    and<\/td>\n($x and $y) is true.<\/td>\nAND operator.<\/td>\nIf both the operands are true then condition becomes true.<\/td>\n<\/tr>\n
    or<\/td>\n($x or $y) is true.<\/td>\nOR Operator.<\/td>\nIf any of the two operands are non zero then condition becomes true.<\/td>\n<\/tr>\n
    !<\/td>\n!($x && $y) is false.<\/td>\nNOT Operator.<\/td>\nUse to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.<\/td>\n<\/tr>\n
    &&<\/td>\n($x && $y) is true.<\/td>\nAND operator.<\/td>\nIf both the operands are non zero then condition becomes true.<\/td>\n<\/tr>\n
    ||<\/td>\n($x || $y) is true.<\/td>\nOR Operator.<\/td>\nIf any of the two operands are non zero then condition becomes true.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Assignment Operators\u00a0in PHP:<\/h2>\n

    Assignment Operators are those operator which perform assignment of value in variable according to operator.In \u00a0php there are many\u00a0Assignment Operators .Don\\’t get Confuse between \\”=\\”<\/strong> and \\”==\\”<\/strong>.in PHP\u00a0\\”=\\”<\/strong> is assignment operator<\/strong> where as\u00a0\\”==\\”<\/strong> is Comparison operator\u00a0<\/strong><\/p>\n\n\n\n\n\n\n\n\n\n
    Operator<\/strong><\/td>\nExample<\/strong><\/td>\nWorking As<\/strong><\/td>\nOperation Performed<\/strong><\/td>\n<\/tr>\n
    =<\/td>\n$z = $x + $y<\/td>\nassign value of $x + $y into $z<\/td>\nSimple assignment operator, Assigns values from right side operands to left side operand<\/td>\n<\/tr>\n
    +=<\/td>\n$z += $x<\/td>\n$z = $z + $x<\/td>\nAdd AND assignment operator, It adds right operand to the left operand and assign the result to left operand<\/td>\n<\/tr>\n
    -=<\/td>\n$z -= $x<\/td>\n$z = $z -$x<\/td>\nSubtract AND assignment operator, It subtracts right operand from the left operand and assign the result to left operand<\/td>\n<\/tr>\n
    *=<\/td>\n$z *= $x<\/td>\n$z = $z * $x<\/td>\nMultiply AND assignment operator, It multiplies right operand with the left operand and assign the result to left operand<\/td>\n<\/tr>\n
    \/=<\/td>\n$z \/= $x<\/td>\n$z = $z \/ $x<\/td>\nDivide AND assignment operator, It divides left operand with the right operand and assign the result to left operand<\/td>\n<\/tr>\n
    %=<\/td>\n$z %= $x<\/td>\n$z = $z % $x<\/td>\nModulus AND assignment operator, It takes modulus using two operands and assign the result to left operand<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    Conditional Operator\u00a0in PHP:<\/h2>\n

    Conditional Operator is sometimes also called\u00a0ternary operator.In ternary Operator \u00a0first Checks an expression for a true or false value and then perform given statements depending upon the result of the evaluation.<\/p>\n

    Assume $x and $y \u00a0are two\u00a0 variables <\/a> having value $x=10 ,$y=5, Then the Result will be give by Operators are<\/p>\n
