PHP imagechar Function: Drawing a Character on an Image

The imagechar function in PHP draws the first character of a string onto a specified image at coordinates (x, y) with a given color and font size. The function signature is:

bool imagechar(resource $image, int $font, int $x, int $y, string $c, int $color)

If $font is 1‑5, a built‑in font is used (larger numbers correspond to larger fonts). On success, the function returns the transformed image; on failure it returns FALSE.

Below is a complete example that creates a 100×100 image, allocates white and black colors, draws the character "P" in the top‑left corner, sends the appropriate header, and outputs the image as PNG:

<?php
$im = imagecreate(100, 100);
$string = 'PHP';
$bg = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
// prints a black "P" in the top left corner
imagechar($im, 1, 0, 0, $string, $black);
header('Content-type: image/png');
imagepng($im);
?>
