A practical example to see the difference would be: $i = 1; echo $i; // 1 echo $i++; // 1 echo $i; // 2 echo ++$i; //3 You will only find difference if you use this within an expression.

So here I am sharing some more … WebThe first notation operand++ is called post-increment, and the second notation ++operand is called pre-increment. Post-increment means, the value of the operand is incremented after the execution of current statement. Pre-increment means, the value of the operand is incremented and then the current statement is executed.
WebA pre-increment operator (++) is used to increment the value of an operand (variable) before using it in an expression. It means when we use a pre-increment (++) operator then the value of the operand (variable) increases immediately by 1. The result is the value of the (operand+1). result = ++iData; // apply pre increment on iData \/ WebPHP supports C-style pre- and post-increment and decrement operators. Note: The increment/decrement operators only affect numbers and strings. Arrays, objects, booleans and resources are not affected. Decrementing null values has no effect too, but incrementing them results in 1. Here's a simple example script:

WebThe difference between pre- and post-increment is in the result of evaluating the expression itself. ++i increments i and evaluates to the new value of i. i++ evaluates to the old value of i, and increments i. The reason this doesn't matter in a for loop is that the flow of control works roughly like this: test the condition; if it is false ...
