Brother, can you help the younger brother solve this problem, PHP foreach loop to get all the values inside the static page display

if ($_post[size]<> "")
{$size =$_post[size];
$myarr =split ("/", $size);
$size 1 = " "; foreach ($myarr as $key = + $value) {$size 2 = "". $value." ";} $size 3 = "";
$size 4= $size 1. $size 2. $size 3;
}

$html 1=str_replace ("{size}", $size 4, $html 1);

If the above code is displayed directly with a dynamic display, it can be displayed directly by adding an echo, but I am using it to generate a static page,,,,,

Add me to the size of this text box to input 1/2/3/4 characters,,,/split. And then loop it out,,,,,,,, but the loop out takes the value is the last 4,,, what I want is to take all ... Then generate to the static page to go.

As below:

1234

Hope to help me, thank you!
