Traversing the word, then a full explanation is that a read access time, displayed literally.
Since for a simple loop count is circulating, and the subscript value of the array index is an integer. Therefore, we can iterate through the array index for loop.
? <PHP // declare an array values are 1 to 10 $ NUM = Array (1,2,3,4,5,6,7,8,9,10); // accordance with the characteristics of the array index, the subscript start from zero. Therefore, the subscript index of 1 to 0,10. 9 echo $ NUM [0] '<br />';. Echo $ NUM [. 9] '<br />';. // we can obtain an array element the total number, of 10 echo COUNT ($ NUM); // traverse the array index, we can define a variable I $ @ I $ 0 value, starting from 0 @ cycle can be set to a conditions: $ i lower target (9) loop within the maximum value for ($ I = 0; $ I <COUNT ($ NUM); $ I ++) { echo $ NUM [$ I] '<br />';. } ?>
