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().
#Php echo once 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 The If condition inside the for loop will exit the loop when the value of $i exceeds 5 ( that is when it equals to 6)Ĭontinue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.Ībove code will print 1 to 10 except the number 5. Check the ouput just outside the for loop.Įcho " Value of \$i Outside the loop: ".$i īy using break we can exit the loop without completing the total required loopings (early exit). For and foreach loop in PHP with break statement and creating patterns using nested for loopsĮxpr3 is executed at the end of the loop.
