Example
The
forstatement is used when you know how many times you want to execute a statement or a block of statements.
The initializer is used to set the start value for the counter of the number of loop iterations. A variable may be declared here for this purpose and it is traditional to name it $i.
The following example iterates 10 times and displays numbers from 0 to 9.
for ($i = 0; $i <= 9; $i++) {
echo $i, ',';
}
# Example 2
for ($i = 0; ; $i++) {
if ($i > 9) {
break;
}
echo $i, ',';
}
# Example 3
$i = 0;
for (; ; ) {
if ($i > 9) {
break;
}
echo $i, ',';
$i++;
}
# Example 4
for ($i = 0, $j = 0; $i <= 9; $j += $i, print $i. ',', $i++);
The expected output is:
0,1,2,3,4,5,6,7,8,9,
