Php operation array

Php operation array

for($i=1;$i<=5;$i++){array(array($i));}

The for loop contains a two-dimensional array. I want to merge the two-dimensional array in the for loop and print the result as follows:

array( [0] => Array        (      [0] => 1     ) [1] => Array        (      [0] => 2       ) [2] => Array        (      [0] => 3      ) [3] => Array        (      [0] => 4  ) [4] => Array        (       [0] => 5       ))

$rs = array();for($i=0; $i<=5; $i++) {    $rs[] = array($i);}

$rs = array();for($i=0; $i<=5; $i++) {    $rs[] = array($i);}

This method does not work. The array ($ I) on the right must be a two-dimensional array.

$rs = array();for($i=0; $i<=5; $i++) {    $rs[] = array($i);}

This method does not work. The array ($ I) on the right must be a two-dimensional array.
Have you run my code?

I know the result is correct, but you cannot do this.

$rs[] = array($i);

The right side must be:

array(array($i))

$ Rs = array (); for ($ I = 0; $ I <= 5; $ I ++) {$ tmp = array ($ I )); // do you want to do this? $ Rs [] = $ tmp [0];}

$ Rs = array (); for ($ I = 0; $ I <= 5; $ I ++) {$ tmp = array ($ I )); // do you want to do this? $ Rs [] = $ tmp [0];}

This method does not work. you can only get the number of $ I. If there are other elements in the two-dimensional array, you cannot get it.

for($i=1;$i<=5;$i++){  $res[$i] = array(array($i));}

for($i=1;$i<=5;$i++){  $res[$i] = array(array($i));}

The result is a three-dimensional array.

$res = array();for($i=1;$i<=5;$i++){  $res = array_merge($res, array(array($i)));}print_r($res);

Array
(
[0] => Array
(
[0] => 1
)

[1] => Array
(
[0] => 2
)

[2] => Array
(
[0] => 3
)

[3] => Array
(
[0] => 4
)

[4] => Array
(
[0] => 5
)

)

OK, positive solution. thank you, boss.
