$image = ImageCreateFromJPEG( "img/6.jpg" );
$cor = imagecolorallocate($image, 0, 0, 0);
$font = ‘debiao.ttf‘;
$tt = ‘我们的灵魂‘;
$a = im($image, 120, 0, 150, 150, $cor, $font, $tt,50);
header(‘Content-type: image/jpeg‘);
imagejpeg($image);
function im(&$image, $size, $angle, $start_x, $y, $color, $font, $text,$spancing) {
for ($i=0;$i<mb_strlen($text,‘utf8‘);$i++) {
$t = mb_substr($text, $i,1,‘utf8‘);
$x = $i*($size+$spancing);
imagettftext($image, $size, $angle, $x+$start_x, $y, $color, $font, $t);
}
}封装的可以控制往图片上写字，控制字符间距的方法
