The following example illustrates that
break is used to break out of the currently executing loop and no longer continue to execute the loop.

Copy code The code is as follows:

$i = 0;
while ($i < 7) {
if ($arr[$i] == "stop") {
break;
}
$i++;
}
? >

continue immediately stops the current execution loop and returns to the conditional judgment of the loop to continue the next loop.
Copy code The code is as follows:

while (list($key,$ value) = each($arr)) {
if ($key == "zhoz"){ // If the value of the queried object is equal to zhoz, this record will not be displayed.
continue;
}
do_something ($value);
}
// Example 2
foreach ($list as $temp) {
if ($temp-> ;value == "zhoz") {
continue; // If the value of the queried object is equal to zhoz, this record will not be displayed.
}
do_list; // The records in the array are displayed here
}
?>

Note: the goto loop instruction cannot be used in PHP.
