I'm merging text into an image using:
$msg = 'string1:' . $string1 . ' string2: ' . $string2;
$text = imagecreatetruecolor($width, $height);
imagestring($text, 5, 50, 50, $msg, 0x00ff00);
imagecopymerge($final, $text, 50, 50, 50, 50, $width, $height, 100);
The above works.
What I want to do is have ' string2: ' . $string2 show on a new line. How?
Anything with the quotes displays as a literal, e.g., '\r\n string2'
outputs as \r\n\string2, as does <br> and anything else, just as the
manual says it will. I tried adding the string PCP_EOL, but it didn't
play. I tried $msg = nl2br(string to output) with \r\n within the string,
but it doesn't play.
So...how do I produce cr/lf?

The php.net description of the imagestring() function
(http://php.net/manual/en/function.imagestring.php) says that it draws "a
string horizontally".
I believe that the function is not constructed to draw multiple lines, but
only text in a single horizontal line.
So, to draw two strings, one line apart, you make two calls to
imagestring(), with two individual strings.
The second call should use the first call's x and y values, offset by the
font size (imagefontheight()) plus the amount of space between each line.

+1 -= works for me.

The OP asked for CR and LF, which is what I gave. 21 is NAK and 37 is %,

One thing to note,
$a = '\r\n'; will set $a to a string of 4 characters ( \ r \ n)
$b = "\r\n"; will set $b to a string of 2 characters, return and new-line
The type of quote around the string makes a big difference to how the
insides are parsed.

He's using ASCII??
37 is Line Feed,
13 is Carriage Return, and
21 is New Line
in EBCDIC. And, PHP runs on EBCDIC machines.
Better to use '\r' for Carriage Return, and '\n' for Linefeed / Newline, or
PHP defined constant (iirc, $PHP_EOL), and let PHP decide which platform,
which characterset, and which codepoints to use.
Or, better still, use the proper function (in the OP's case, another call to
imagestring() ) to achieve the proper text alignment.

Thanks for all the replies.
WRT all the suggested strings for cr/lf, none of them seem to play in this
application. For example, using $br = "\r\n" or $br = chr(10).chr(13),
etc., appended as:
$msg = 'string1:' . $string1.$br. ' string2: ' . $string2;
yields only strange characters after string1, then, on the same line
prints string2.
Lew Pitcher's first suggestion works -- make two calls to
imagestring(), with two individual strings..
Thanks all.

yep. NBasically build your own function that does the formatting.
I had to do that for GD and for PDFlite to flow text into PDF documents.
imagestring is [a] primitive...:LOL
