It seems this is just the behaviour when echo'ing an array rather than a string.
For example it outputs the line count if I do:
PHP Code:
echo(("Message_"@temp.i).getlines().size());
//13
//13
//13
You can coerce the array to a string by doing:
PHP Code:
echo(@ ("Message_"@temp.i).getlines());
//ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH
//ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH
//ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH,ASDFGH
