求大神解决下php数组循环的问题
我有一个数组如下
$arr = array(1,2,3,4,5,6,7,8);
希望用循环输出
start1
1
2
3
4
end1
start2
1
2
3
4
end2
----------------------------------------------------------
start1
5
6
7
8
end1
start2
5
6
7
8
end2
意思就是把数组 每4个一分组
而且每组要重复两次
------解决思路----------------------
<br><?php<br><br>$arr = array(1,2,3,4,5,6,7,8);<br><br>for($i=0; $i<count($arr); $i+=4){<br> $temp = array_slice($arr, $i, 4);<br> for($k=1; $k<=2; $k++){<br> echo 'start'.$k.'<br>';<br> foreach ($temp as $val) {<br> echo $val.'<br>';<br> }<br> echo 'end'.$k.'<br>';<br> }<br>}<br>------解决思路----------------------
<br>$arr = array(1,2,3,4,5,6,7,8);<br>$n = 2; // 循环2次<br>$split = 4; // 4个为一个分组<br>echo '<pre class="brush:php;toolbar:false;">';<br>response($arr, $n, $split);<br>echo '';
function response($arr, $n, $split){
while(count($arr)>0){
$tmp = array_splice($arr, 0, $split);
for($i=0;$i echo 'start'.($i+1)."\r\n";
echo implode("\r\n", $tmp)."\r\n";
echo 'end'.($i+1)."\r\n";
}
echo "----------------------------------------------------------\r\n";
}
}
<br>start1<br>1<br>2<br>3<br>4<br>end1<br>start2<br>1<br>2<br>3<br>4<br>end2<br>----------------------------------------------------------<br>start1<br>5<br>6<br>7<br>8<br>end1<br>start2<br>5<br>6<br>7<br>8<br>end2<br>
