在for循环中使用条件运算[关闭]

I need to skip certain part of the code if condition is true, How to do it in php

   if ($a==0 && $b==0)
     {

//skip this part of the code and exit loop 
        }

You can use break; to exit from a loop.

Example:

<?php
$arr = array('one', 'two', 'three', 'four', 'stop', 'five');
while (list(, $val) = each($arr)) {
    if ($val == 'stop') {
        break;    /* You could also write 'break 1;' here. */
    }
    echo "$val<br />
";
}
