你的验证码是用什么方式写的?
看下空间上是否有开启这个功能
如果有,看下有没权限创建这个验证码

注释掉声明数据类型的 header 函数,用浏览器直接运行生成程序

<?php    //随机字符串种子,可以换成字母或其他英文字符    $glbVerifySeed = "AbcDefGhijkL1234567890mnOpqRstuvwxYz";    main();            function main() {        session_start();                $verifyCode = getRandomCode();        $_SESSION["verifyCode"] = $verifyCode;        $imgWidth = $_REQUEST["width"];        $imgHeight = $_REQUEST["height"];        $imgFont = $_REQUEST["font"];                if($imgWidth == "") $imgWidth = 50;        if($imgHeight == "") $imgHeight = 20;        if($imgFont == "") $imgFont = 6;        doOutputImg($verifyCode, $imgWidth, $imgHeight, $imgFont);    }        //获取随机数字字符串    function getRandomCode($length=4) {        global $glbVerifySeed;                $bgnIdx = 0;        $endIdx = strlen($glbVerifySeed)-1;                $code = "";        for($i=0; $i<$length; $i++) {            $curPos = rand($bgnIdx, $endIdx);            $code .= substr($glbVerifySeed, $curPos, 1);        }                return $code;    }        //输出校验码图像    function doOutputImg($string, $imgWidth, $imgHeight, $imgFont,        $imgFgColorArr=array(0,0,0), $imgBgColorArr=array(255,255,255)) {        $image = imagecreatetruecolor($imgWidth, $imgHeight);        //用白色背景加黑色边框画个方框        $backColor = imagecolorallocate($image, 255, 255, 255);        $borderColor = imagecolorallocate($image, 255, 255, 255);        imagefilledrectangle($image, 0, 0, $imgWidth - 1, $imgHeight - 1, $backColor);        imagerectangle($image, 0, 0, $imgWidth - 1, $imgHeight - 1, $borderColor);        $imgFgColor = imagecolorallocate ($image, $imgFgColorArr[0], $imgFgColorArr[1], $imgFgColorArr[2]);        doDrawStr($image, $string, $imgFgColor, $imgFont);        doPollute($image, 64);        header('Content-type: image/png');        imagepng($image);        imagedestroy($image);    }    //画出校验码    function doDrawStr($image, $string, $color, $imgFont) {        $imgWidth = imagesx($image);        $imgHeight = imagesy($image);                $count = strlen($string);        $xpace = ($imgWidth/$count);                $x = ($xpace-6)/2;        $y = ($imgHeight/2-8);        for ($p = 0; $p<$count;  $p ++) {            $xoff = rand(-2, +2);            $yoff = rand(-2, +2);            $curChar = substr($string, $p, 1);            imagestring($image, $imgFont, $x+$xoff, $y+$yoff, $curChar, $color);            $x += $xpace;        }        return 0;    }        //画出一些杂点    function doPollute($image, $times) {           $imgWidth = imagesx($image);        $imgHeight = imagesy($image);        for($j=0; $j<$times; $j++) {            $x = rand(0, $imgWidth);            $y = rand(0, $imgHeight);                        $color = imagecolorallocate($image, rand(0,255), rand(0,255), rand(0,255));            imagesetpixel($image, $x, $y, $color);        }    }?>
