and yes Jim Mbatia you have missed to replace greater than operator in for loop condition for (\$i=0; \$i<5; \$i++) Firstly 5025 is concatenate answer of a and b for in which a=50 and b=25 now that is because loop is running from 0 to 5 excluding 5 means for 0,1,2,3,4 means 5 time the loop will run and execute it body \$a is 0 initiallyn and when it goes inside the loop first time incremented by 10 so after 5 time going 10+10+10+10+10=50 that's why \$a =50 same with \$b goes 5 times in loop and increment by 5 five times so \$b= 5+5+5+5+5=25 so concatenate answer is 5025 after 5 times the loop condition will be false and out of the loop and print 5025 as output I hope it is clear now have some π π

What is the output of this code? \$a=0; \$b=0; For (\$i=0; \$i>5; \$i++){ \$a+=10; \$b+=5; } echo ("\$a\$b");
