php 圖片水印中文亂碼解決方法是要轉入一款中文字體就以了,如果你在生成水印有中文時,又沒載入相關的字體的話,那中文肯定會是亂碼的,如果是英語字母那載不載入都沒關系,代碼如下:

$name =  iconv("gb2312","utf-8",www.survivalescaperooms.com php粉絲網);

$font = 'simhei.ttf';//水印字體

$im = imagecreatefromjpeg("test.jpg");//載入圖片

$black = imagecolorallocate($im, 0, 0, 0);//設置顏色

imagettftext($im, 12, 0, 320, 84, $black, $font, $name);//打印水印

imagepng($im);//輸出圖片,如果要保存加個保存路徑和文件名,如imagepng($im,'test1.jpg');   //開源代碼Vevb.com

imagedestroy($im);//清空緩存

下面來看一款生成水印文字函數,代碼如下:

function str2pic ($string,$source,$destination="",$f,$fontsize=10,$shadowcolor="#ffffff",$f,$x=10,$y=10) {

//header('content-type:image/png');

    $pi=pathinfo($source);

    $pie=$pi[extension];#獲取擴展名

    if(eregi("jpg|jpeg",$pie))$im=@imagecreatefromjpeg($source);

    if(eregi("gif",$pie))$im=@imagecreatefromgif($source);

    if(eregi("png",$pie))$im=@imagecreatefrompng($source);

    $col1=hex2dec($shadowcolor);#陰影顏色

    $col2=hex2dec($fontcolor);#字體顏色

    $col1=imagecolorallocate($im,$col1[0],$col1[1],$col1[2]);

    $col2=imagecolorallocate($im,$col2[0],$col2[1],$col2[2]);

    imagettftext($im,$fontsize,0,$y+1,$x+1,$col1,$fonturl,$string);

    imagettftext($im,$fontsize,0,$y,$x,$col2,$fonturl,$string);

    imagejpeg($im);

    if($destination)imagejpeg($im,$destination);

    imagedestroy($im);

}

function hex2dec($hexcolror) {#十六進制顏色轉換成10進制顏色

    preg_match_all("/([0-f]){2,2}/i",$hexcolror,$matches);

    if(count($matches[0])==3){

    $rr=hexdec($matches[0][0]);

    $gg=hexdec($matches[0][1]);

    $bb=hexdec($matches[0][2]);

    }

    return array($rr,$gg,$bb);

}

?>
