一、图片压缩
/** * 图片压缩 只针对文件后缀名为： jpg，png，jpeg * @param $file 文件路径 * @param $tmp 为文件压缩条件，即当图片的长宽的长度最大的那个，大于$tmp值时进行压缩 * 压缩规则：取图片的长宽最大的那个，再设置为 $tmp 再等比压缩其他 * */ public static function requestImageResize($file,$tmp = 1536){ \Fuel\Core\Log::debug("======================================== Image Resize Begin ====================================="); \Fuel\Core\Log::debug("filePath = $file ");// $tmp = 1536; $strs = explode('.',$file); $index = count($strs) - 1; $str = strtolower($strs[$index]); if( $str == "jpg" || $str == "png"|| $str == "jpeg" ){ list($width, $height) = getimagesize($file); \Fuel\Core\Log::debug("width=$width height=$height"); $newwidth = $width; $newheight = $height; $max = $newheight >= $newwidth ? $newheight:$newwidth; $flag = $newheight >= $newwidth ? 1:2; if($max>$tmp){ \Fuel\Core\Log::debug("resize"); if( $flag == 2 ){ $offset=$width/$tmp; $newwidth=$tmp; $newheight=$height/$offset; }else{ $offset=$height/$tmp; $newheight=$tmp; $newwidth=$width/$offset; } $src_im = imagecreatefromjpeg($file); $dst_im = imagecreatetruecolor($newwidth, $newheight); imagecopyresized($dst_im, $src_im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); imagejpeg($dst_im,$file); //输出压缩后的图片 imagedestroy($dst_im); imagedestroy($src_im); }else{ \Fuel\Core\Log::debug("no resize"); } } \Fuel\Core\Log::debug("======================================== Image Resize End ====================================="); } 二、视频压缩
这里需要安装 Mplayer
/** ** @param $in 源文件路径 * @param $out_vid 目的文件路径 * @return mixed 目的文件路径 * MPlayer-mingw32-1.0rc1 ffmpeg */public static function flv_convert($in, $out_vid){ \Fuel\Core\Log::debug(date("Y-m-j H:i:s")." =================== flv_convert $in to $out_vid begin"); $cmd = 'mencoder '.$in.' -o '.$out_vid.' -af volume=10 -aspect 16:9 -of avi -noodml -ovc x264 -x264encopts bitrate=500:level_idc=41:bframes=3:frameref=2: nopsnr: nossim: pass=1: threads=auto -oac mp3lame'; $res = shell_exec($cmd); \Fuel\Core\Log::debug(date("Y-m-j H:i:s")." =================== flv_convert $in to $out_vid finish"); return $out_vid;} 三、生成 excel 文件
其中文件保存路径$fileName，我这里使用的是相对路径
/** * @param array $head 头部（如果要输出序号就要在这里的第一个添加需要标识） * @param array $data 数据 * @param bool $data_id_flag 标识是否需要输出序号，如果是则在每一行前面输出序号 * @return string 输出文件保存位置 * @throws PHPExcel_Exception * @throws PHPExcel_Writer_Exception */public static function doExportExcel($head = array(),$data = array(),$data_id_flag = true ){ $objPHPExcel = new PHPExcel(); //表头 $start = 'A';//初始格代表A $col = 1;//初始格 foreach($head as $key=>$row){ $cell = $start.$col; $objPHPExcel->setActiveSheetIndex(0) ->setCellValue($cell, $row); $objPHPExcel->getActiveSheet()->getStyle($cell)->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle($cell)->getAlignment()->setWrapText(true); $objPHPExcel->getActiveSheet()->getColumnDimension($start)->setAutoSize(true); #设置字体 $objFontA5 = $objPHPExcel->getActiveSheet()->getStyle($cell)->getFont(); $objFontA5->setName('Microsoft Yahei'); $objFontA5->setSize(11); $objFontA5->setBold(true); $objFontA5->getColor()->setARGB('FF333333'); $start = ++$start; } //数据 $start = 'A';//初始格代表A $col = 2;//初始格 $j = 1; foreach($data as $rows){ if($data_id_flag){ $cell = $start.$col; $objPHPExcel->setActiveSheetIndex(0) ->setCellValueExplicit($cell,$j++ , PHPExcel_Cell_DataType::TYPE_STRING); $start = ++$start; } foreach($rows as $key=>$val){ $cell = $start.$col; $objPHPExcel->setActiveSheetIndex(0) ->setCellValueExplicit($cell, $val, PHPExcel_Cell_DataType::TYPE_STRING); $start = ++$start; } $col++; $start = 'A'; } // Rename sheet $objPHPExcel->getActiveSheet()->setTitle('DataSheet'); // Set active sheet index to the first sheet, so Excel opens this as the first sheet $objPHPExcel->setActiveSheetIndex(0); $savefilename = "data ".date('Ymd His').".xls"; //文件保存路径，这里可做修改 $fileName = 'file/'.$savefilename; header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="'.$savefilename.'"'); header('Cache-Control: max-age=0'); $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel); $objWriter->save($fileName); return $fileName; } 四、pdf转图片
这里需要在安装 ImageMagick 和得到相应的 dll 然后再修改配置 php.ini 添加 extension=php_imagick.dll;
注意：要安装对版本
/** * @param $PDF 绝对路径 * @param $Path 绝对路径 * @return array * 安装 ImageMagick-6.8.6-Q16 和 相应的 dll */public static function pdf2png($PDF,$Path){ if(!extension_loaded('imagick')){ echo "imagick extension_loaded fail"; return false; } if(!file_exists($PDF)){ echo $PDF; return false; } $IM = new Imagick(); $IM->setResolution(120,120); $IM->setCompressionQuality(100); $IM->readImage($PDF); foreach($IM as $Key => $Var){ $Var->setImageFormat('png'); $Filename = $Path.'/'.md5($Key.time()).'.png'; if($Var->writeImage($Filename)==true){ $Return[]= $Filename; } } return $Return;} 五、word转pdf
需要安装 openoffice 和
/** * word 文档转pdf * @param $doc_url 源文档的全路径 * @param string $output_url 索要保存的路径包括文件名 * 需要安装 openoffice 和 配置其访问权限 * 博客 http://www.firerise.com.cn/article_ar71.html */public static function word2pdf($doc_url,$output_url="file:///Q:/bsl/wujixian/shengchang/qiye/8/infiniteus-sharefun/web/public/file"){ $output_url = $output_url."/1.pdf"; echo $output_url; $osm = new COM("com.sun.star.ServiceManager")or die ("Please be sure that OpenOffice.org is installed.n"); echo "sss"; $args = array(Service_Util::MakePropertyValue("Hidden",true,$osm)); $oDesktop = $osm->createInstance("com.sun.star.frame.Desktop"); $oWriterDoc = $oDesktop->loadComponentFromURL($doc_url,"_blank", 0, $args); $export_args = array(Service_Util::MakePropertyValue("FilterName","writer_pdf_Export",$osm)); $oWriterDoc->storeToURL($output_url,$export_args); $oWriterDoc->close(true);}/** * 辅助 word2pdf 方法完成功能 * @param $name * @param $value * @param $osm * @return mixed */static function MakePropertyValue($name,$value,$osm){ $oStruct = $osm->Bridge_GetStruct("com.sun.star.beans.PropertyValue"); $oStruct->Name = $name; $oStruct->Value = $value; return $oStruct;}
