PHP新手在这里。我想问一下我的嵌套循环的帮助。我认为我很接近,但我很确定我缺少的是转换或休息或两者兼而有之。我已经搞砸了一段时间,但我只是不能正确地做。这里是代码示例。PHP嵌套循环
<?php $items=array(thing01,thing02,thing03,thing04,thing05,thing06,thing07,thing08,thing09,thing10,thing11,thing12,thing13,thing14,thing15,thing16,thing17,thing18,thing19,thing20,thing21,thing22,thing23,thing24,thing25,thing26,thing27,thing28,thing29,thing30,thing31,thing32); ?>
<?php $array_count = count($items); ?>
<?php $item_count = 9; ?>
<?php $blk_Number = ceil($array_count/$item_count); ?>
<?php echo "<h3>This list should contain " . $array_count . " items</h3>"; ?>
<ul>
<?php
for ($pas_Number = 1; $pas_Number <= $blk_Number; $pas_Number++) {print "<h3>Start of Block " . $pas_Number . " of 9 items</h3>";
for ($key_Number = 0; $key_Number < $item_count; $key_Number++){print "<li>" . $items[$key_Number] . "</li>"; }
{print "<h3>End of Block " . $pas_Number . " of 9 items</h3>"; }
}
; ?>
</ul>
这是给我的输出:
此列表应该包含32项
Start of Block 1 of 9 items
thing01
thing02
thing03
thing04
thing05
thing06
thing07
thing08
thing09
End of Block 1 of 9 items
Start of Block 2 of 9 items
thing01
thing02
thing03
thing04
thing05
thing06
thing07
thing08
thing09
End of Block 2 of 9 items
Start of Block 3 of 9 items
thing01
thing02
thing03
thing04
thing05
thing06
thing07
thing08
thing09
End of Block 3 of 9 items
Start of Block 4 of 9 items
thing01
thing02
thing03
thing04
thing05
thing06
thing07
thing08
thing09
Start of Block 4 of 9 items
thing01
thing02
thing03
thing04
thing05
thing06
thing07
thing08
thing09
End of Block 4 of 9 items
正如你可以看到数组元素的个数是错误的。第2块应包含10-18项,第3块应包含第19-27项,第4块应包含剩余的5项“东西”。我对阵列中所有愚蠢的元素表示歉意,但我想能够清楚地解释我想要做的事情。
哇...从来不知道array_chunk它完美的工作!谢谢 – 2012-08-15 06:13:15
