PHP: The difference between break and continue flow control instructions

In the commonly used for and

foreach loops in php, we often encounter conditional judgment or abort the loop. The processing method mainly uses two process control instructions, break and continue. Now the main differences will be explained.

The following examples illustrate
break is used to jump out. The currently executing loop will no longer continue to execute the loop.

The code is as follows:

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


continue Immediately stops the current execution loop and returns to the condition judgment point of the loop to continue the next loop.

The code is as follows:

<?php 
while (list($key,$value) = each($arr)) { 
if ($key == "zhoz"){ // 如果
查询
到对象的值等于zhoz,这条记录就不会显示出来了。 
continue; 
} 
do_something ($value); 
} 
//  例子2 
foreach ($list as $temp) { 
if ($temp->value == "zhoz") { 
continue; // 如果查询到对象的值等于zhoz,这条记录就不会显示出来了。 
} 
do_list; // 这里显示
数组
中的记录 
} 
?>


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

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
