Question

EDITED

$queryPremium ="Select * from tablename where premium = 1 order by id desc";
$rowPremium = mysql_query($queryPremium);

$queryNotPremium ="Select * from tablename where premium = 0 order by id desc";
$rowNotPremium = mysql_query($queryNotPremium);

现在我想要一个单独的数组，其中rowNotPremium的顺序将被维护，$ rowPremium将在$ rowNotPremium的2个数据之后或$ rowNotPremium的3data之后随机插入...

怎么做？

Answer 1

你可以这样做：

$newArray = array_merge($nonpremium, $premium)

或

df %>% lm(count~trt1:trt2-1, .) %>% .$coef
#### trt1far:trt2A trt1near:trt2A  trt1far:trt2B trt1near:trt2B 
####      4.000000       4.333333       4.000000       4.666667

Answer 3

使用array_splice()和rand()函数

$array1 = array( 1,2,3,4,5 );
$array2 = array( 6,7,8,9 ); 
array_splice( $array1, rand(0,count($array2)-1), 0, $array2 ); // splice in at random position

在数组中插入新元素
