Php Assignment Operators

In general, " =" and "-=" are the most widely used combination operators.In addition to this "shorterhand" technique, you can specify whether you want to increment before the line of code is being executed or after the line has executed. $x = 4; echo "The value of x with post-plusplus = " .so the output will become: In the above example Variable( $x) with value=100. ($x*=10) now value 10 multiply with previous value(100). it gives remainder value=”1″ and this remainder assign again to variable($x). Now concatenate this string to another string using the same variable by performing ($str.=”to the world of php”).

$x; echo " The value of x after the pre-plusplus is " .

$x; As you can see the value of $x is not reflected in the echoed text because the variable is not incremented until after the line of code is executed.

PHP Forum In all programming languages, operators are used to manipulate or perform operations on variables and values.

You have already seen the string concatenation operator "." in the Echo Lesson and the assignment operator "=" in pretty much every PHP example so far. Modulus is the remainder after the division operation has been performed.However, with the pre-increment " $x" the variable does reflect the addition immediately.If you would rather download the PDF of this tutorial, check out our PHP e Book from the store.In this tutorial you will learn how to manipulate or perform the operations on variables and values using operators in PHP.Operators are symbols that tell the PHP processor to perform certain actions.The arithmetic operators are used to perform common arithmetical operations, such as addition, subtraction, multiplication etc.Here's a complete list of PHP's arithmetic operators: "Pink"); $z = $x $y; // Union of $x and $y var_dump($z); var_dump($x == $y); // Outputs: boolean false var_dump($x === $y); // Outputs: boolean false var_dump($x !In this case it was 5 / 2, which has a remainder of 1.Comparisons are used to check the relationship between variables and/or values.The downside to this combination operator is that it reduces code readability to those programmers who are not used to such an operator.Here are some examples of other common shorthand operators.
