Add text to the pictures you post at any time

function makethumb($srcFile,$text,$size=12,$R=0,$G=0 ,$B=0) {

$data = GetImageSize($ srcFile,&$info);

//$kk=13;
$txt=substr( $text, $start, $len);
$hei=$i*$lgg+$kk;
imagettftext($ni,$size, 0, 8, $hei, $textcolor, $font, $txt); // Write the text with a font
$i++;

makethumb("face.jpg",$text ,$size,$R,$G,$B);

The above has introduced the PHP watermark for adding text to the pictures you post at any time. It also includes the content of the "Give yourself a smile" composition. I hope it will be helpful to friends who are interested in PHP tutorials.
