The for loop has
three semicolon-separated expressions within its parentheses.
These three expressions function respectively as the
initialization, the condition, and the reinitialization
expressions of the loop. The for loop can be defined in terms of the
corresponding while
loop:
for ($i = 1; $i < 10; $i++) {
...
}This is the same as:
$i = 1;
while ($i < 10) {
...
}
continue {
$i++;
}
