Get single "elements" from a PHP variable

I am new to PHP and don't know much about PHP. I just understand some basics.

I have a PHP variable called $myVariable. This variable is filled with strings which I loaded from the internal system. I know how to load the strings from the system and this works so far. So my variable looks like this when I try to echo:

String1 123 Test
String2 456 Test2
String3 789 Test3

etc.

My question now is: How can I work with a single line? I mean if I just want to use Line 1 (String1 123 Test), how can I do that? For example I just want to echo line 1. I tried this so far:

<?php echo $myVariable; ?>

But this echo the whole variable (what is logical). Have I to work with an array or something like this? If yes, can you give me an example?

Thanks in advance

You have to split your variable.

if your want to split when there are a new line use:

$output= preg_split('/\r\n|\r|\n/', $myvariable);

Else you can use the explode function: https://www.php.net/explode

Make use of explode with PHP_EOL

$str="String1 123 Test
String2 456 Test2
String3 789 Test3";

$newarr = explode(PHP_EOL,$str);
//print_r($newarr);

echo $newarr[0]; // "prints" String1 123 Test
echo $newarr[1]; // "prints" String2 456 Test2
echo $newarr[2]; // "prints" String3 789 Test3

Assuming each line seperated by a new line (if it is not new line replace "\n" with the delimiter)

$pieces = explode("\n", $myVariavle);
echo $pieces[0]; //For your first line

$arr = explode(LINE_SEPARATOR,$myVariable);

so probably its:

$arr = explode("\n",$myVariable);

You can access every line by $arr[INDEX] where INDEX is line no from 0 to count($arr)-1
