for($i=0;$i<=2;$i+=0.1){
echo $i."<br>";
}
The result I wish is:
0
0.1
0.2
0.3
0.4
0.5
0.6
0.7
0.8
0.9
1
1.1
1.2
1.3
1.4
1.5
1.6
1.7
1.8
1.9

What happens instead is the loop reaches 1.9 and stops. Why?

This is a silly example, but it's common for infinite loops to accidentally occur. Most of the times, it's because the variables used in the condition are not being updated correctly, or because the looping condition is in error. We print out x, y, and z since these variables appear in the condition.
A for loop works as long as the condition is true. The flow of control, at first comes to the declaration, then checks the condition. If the condition is true, then it executes the statements in the scope of the loop. At last, the control comes to the iterative statements and again checks the condition.
An infinite loop occurs when the condition in the While statement is not satisfied. The loop will continue to run until you manually end the program. This often causes a computer to lock up and may require the computer be restarted.
Because, it will never achieve floating point == integer
