为什么PHP爆炸总是在每个数组的末尾添加'换行符'？

I want to explode ' ' in a string but php add it again.

here's my code:

$str = "MyText1
MyText2
MyText3";

//convert to array
$arr = explode("
", $str); //Why PHP adding '
' again here??

//prepare the var
$new_str = "";

//combine to string again
foreach( $arr as $value ) {
    $new_str .= "prefix-" . $value . "-suffix ";
}

echo $new_str;

the result is:

prefix-MyText1
-suffix prefix-MyText2
-suffix prefix-MyText3-suffix 

I want the result to be:

prefix-MyText1-suffix prefix-MyText2-suffix prefix-MyText3-suffix 

I found the problem. it works on linux, it wont work on windows. linux uses " ", windows uses " "
