GD库在php中默认是没有开启的,如果想让它支持图片处理功能我们需要在php.ini中把extension=php_gd2.dll 去掉前面的;就行了就行了。

在windows服务器开启php的gd库时,使用cgi之后phpinfo()得到的结果中 Configure Command 中并没有出现gd.

将php.ini文件找到extension=php_gd2.dll  去掉前面的;就行了。

另外附上如何检测是否已经安装好GD库代码!

 代码如下 复制代码

if(extension_loaded('gd')) {
  echo '你可以使用gd
';
  foreach(gd_info() as $cate=>$value)
    echo "$cate: $value
";
}else
  echo '你没有安装gd扩展';
?>

结果显示为:你可以使用gd
GD Version: bundled (2.0.34 compatible)

如果有问题,

Configure Command 后显示的是:

1 cscript /nologo configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack" "--without-mssql" "--without-pdo-mssql" "--without-pi3web" "--with-pdo-oci=C:php-sdkoracleinstantclient10sdk,shared" "--with-oci8=C:php-sdkoracleinstantclient10sdk,shared" "--with-oci8-11g=C:php-sdkoracleinstantclient11sdk,shared" "--enable-object-out-dir=../obj/" "--enable-com-dotnet=shared" "--with-mcrypt=static" "--disable-static-analyze" "--with-pgo"

可能的原因:

1.权限问题;

2.双通道是否存在问题,或者是硬件是否松动

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
