Copy part of string

Please read the comment inside the script

<?php
$Messagecode="
100 Can't read
200 Can write
300 Can't write
400 Can write
500 Can't delete
600 Can Delete
700 Upload okay
800 Bad Username.
";

$Code=100;
//some script here.
//something like, look inside the $Messagecode, if the $Code is match on of the line in the $Messagecode then copy that line. and print it.

if(isset($Code) && $Code =='100'){
//copy part of the string, the result should be Can't read
}
if(isset($Code) && $Code =='200'){
//copy part of the string, the result should be Can write
}

****IF NOT MATCH ANY OF THOSE CODE,
Echo "Code not found";
?>

May I suggest using an array?

<?php
$messagecode = Array(100 => "Can't Read", 200 => "Can Write", 300 => "Can't Write", 400 => "Can Write", 500 => "Can't Delete", 600 => "Can Delete", 700 => "upload OKAY", 800 => "Bad Username");
 
$Code = 100;
echo $messagecode[$Code];
 
?>

The reason I listed my codes by lines is because my script is reading those values from a file.
Is there any alternative choice?

100 Can't read
200 Can write
300 Can't write
400 Can write
500 Can't delete
600 Can Delete
700 Upload okay
800 Bad Username.

my bet,
I mean detect the last line which is the "800 Bad Username."
If I change the $Code to a different number, the script will not able to dectect.

for example $Code=600;

sorry small mistake ..
change

if(preg_match("/($Code).*?\n$/",$Messagecode,$match)) {

with

if(preg_match("/($Code).*?\n/",$Messagecode,$match)) {
