我不知道如何命名,以及如何命名:
<?php
$a = ['a1','a2','a3','a4']; // and more a5 … a42
$b = ['b1','b2','b3','b4'];
$c = ['c1','c2','c3','c4'];
// want
$full = ['a1','b1','c1',
'c2','a2','b2',
'b3','c3','a3',
'a4','b4','c4'];
print_r($full);
它类似于 a , b , c ,a,b, c ,< strong> a , b ,c,a, b , c , a ,解决方案是一个数学系列?

Need to merge all the array, Please go through this PHP code.
$a = array('a1','a2','a3','a4'); // and more a5 … a42
$b = array('b1','b2','b3','b4');
$c = array('c1','c2','c3','c4');
$d = array_merge($a,$b,$c);
echo mathseries($d,3);
function mathseries($d=array(),$break_number) {
$f = count($d) / $break_number;
for($i=0;$i<$f;$i++) {
$r[] = $d[$i].','.$d[$i+$f].','.$d[$i+($f*2)];
}
$r = implode(',',$r);
return $r;
}
create a function in which two parameter send, 1st parameter array. 2nd parameter is break point.

$arr = [$a, $b, $c];
$full = [];
$i = 0;
$k = 0;
for ($j = 0; $j < count($a); $j++)
do {
$full[] = $arr[$k][$j];
$i = ++$i % 3;
if ($i) $k = ++$k % 3;
} while ($i);
print_r($full);

首先我们创建一个包含三个原始数组的多维数组,然后我们通过两个嵌套的<button onclick="settime();">Set Time</button>
<div class="container">
<video id="video1" class="video-js vjs-default-skin" muted>
<source src="video.m4v" type="video/mp4" />
HTML5 Video is required for this example.
</video>
循环填充目标$result
:
for
的 eval.in demo 强>
要填充$all = [ $a, $b, $c ];
$result = [];
for( $i=0; $i<count( $a ); $i++ )
{
for( $j=0; $j<count( $all ); $j++ )
{
$result[] = $all[ 3*(($i+$j*2)%3>0)-(($i+$j*2)%3) ][ $i ];
}
}
,第二个键$result
是每个原始数组的渐进索引(0,1,2,...);要创建第一个密钥,我们使用此算法:
[$i]
