(PHP 5, PHP 7, PHP 8)
imagexbm — Output an XBM image to browser or file
Outputs or save an XBM version of the given
image.
Note: imagexbm() doesn't apply any padding, so the image width has to be a multiple of 8. This restriction does no longer apply as of PHP 7.0.9.
imageA GdImage object, returned by one of the image creation functions, such as imagecreatetruecolor().
filenameThe path to save the file to, given as string. If null, the raw image stream will be output directly.
The filename (without the .xbm extension) is also
used for the C identifiers of the XBM, whereby non
alphanumeric characters of the current locale are substituted by
underscores. If filename is set to null,
image is used to build the C identifiers.
foreground_colorYou can set the foreground color with this parameter by setting an identifier obtained from imagecolorallocate(). The default foreground color is black. All other colors are treated as background.
Returns true on success or false on failure.
However, if libgd fails to output the image, this function returns true.

Example #1 Saving an XBM file
<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
// Save the image
imagexbm($im, 'simpletext.xbm');
// Free up memory
imagedestroy($im);
?>
Example #2 Saving an XBM file with a different foreground color
<?php
// Create a blank image and add some text
$im = imagecreatetruecolor(120, 20);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color);
// Set a replacement foreground color
$foreground_color = imagecolorallocate($im, 255, 0, 0);
// Save the image
imagexbm($im, NULL, $foreground_color);
// Free up memory
imagedestroy($im);
?>
