在数组中被忽略

I have this Array (part of)

[result] => Array
    (
     [0] => Array        
(
"speciesId": 267,
"source": "Beruf: Verzauberkunst (525)

Formel: Verzauberte Laterne",
)
    )

If I echo out the source everything is in the same line. The gets ignored.

I want that after in the source the output comes in a new line. How is this possible?

Use double quote ("string") instead of single quote('string') when creating array element.

PHP only interprets escaped characters (with the exception of the escaped backslash \ and the escaped single quote \') when in double quotes (")

This works (results in a newline): " "

This does not result in a newline: ' '
