$no=count($a) // Number of elements in array We can get the number of elements and use that in our condition checking. This is not a good idea as the count() function returns the same value in each iteration all the time. Here we are counting number of elements in array in each iteration. We can get number of elements in an array by using count().
Decrement for loop in php how to#
Read how to display elements of an array Speed of looping This will list all the values of the array from starting to end. So we need not call the reset() again( Reset() rewinds array's internal pointer to the first element.
Once the foreach function is called the array pointer will reset to the first element of the array.
While handling PHP Arrays foreach function is required to display the elements of an array. If the condition to check is never meet then it will be an infinite loop execution and PHP execution will hang or stop after reaching maximum execution time. We can reduce the step value in each step of iteration. Similarly $i -=10 is same as $i=$i-10 Decrement step value in loop Now we will use a step value of 10 so the variable $i will increase its value by 10 ( it was increasing by 1 in previous cases ) in each looping. This increase or step value can be changed. So far we have seen each time the variable value is increased by 1. The If condition inside the for loop will exit the loop when the value of $i exceeds 5 ( that is when it equals to 6) Check the ouput just outside the for loop.Įcho " Value of \$i Outside the loop: ".$i īy using break we can exit the loop without completing the total required loopings (early exit). Here condition is checked ( Expr 2) at the staring of the loop.Įxpr3 is executed at the end of the loop. Next time when the value of $i becomes 11 the condition checking fails and the loop is escaped without executing. So in the first loop the value of $i became 1 and in the last loop the value equals to 10. In above case the loop is executed 10 times and each time the value of $i is increased by 1.
