PHP100 essence: PHP upload class supports thumbnails_PHP tutorial

Example:

1. Create the file upfile.php with the following code

//If the parameters from the form are received, upload them, otherwise the form will be displayed

　if(isset($_FILES[uploadinput])){

//Create directory function, the parameter $directoryName does not have "/" at the end,

//If there is, when / is broken into an array, a null value will appear at the end

Function makeDirectory($directoryName) {

$directoryName = str_replace("","/",$directoryName);

　$dirNames = explode(/, $directoryName);

　$total = count($dirNames) ;

　$temp = ;

　for($i=0; $i<$total; $i++) {

　$temp .= $dirNames[$i]./;

　if (!is_dir($temp)) {

　$oldmask = umask(0);

　if (!mkdir($temp, 0777)) exit("Cannot create directory $temp");

umask($oldmask);

　}

　}

return true;

　}

　if($_FILES[uploadinput][name] <> ""){

// Contains upload file class

require_once (class_upload.php);

//Set the file upload directory

　$savePath = "upload";

//Create directory

makeDirectory($savePath);

//Allowed file types

　$fileFormat = array(gif,jpg,jpge,png);

//File size limit, unit: Byte, 1KB = 1000 Byte //2cto.com

　 //0 means no limit, but is affected by the upload_max_filesize setting in php.ini

$maxSize = 0;

// Overwrite the original file? 0 not allowed 1 allowed

$overwrite = 0;

//Initialize upload class

　$f = new clsUpload( $savePath, $fileFormat, $maxSize, $overwrite);

// If you want to generate a thumbnail, call the member function $f->setThumb();

//Parameter list: setThumb($thumb, $thumbWidth = 0, $thumbHeight = 0)

　 //$thumb=1 means to generate thumbnails. When not called, its value is 0

//$thumbWidth thumbnail width, unit is pixel (px), leave it blank and use the default value of 130

　//$thumbHeight The height of the thumbnail in pixels (px). If left blank, the default value of 130 is used

　$f->setThumb(1);

//The uploadinput in the parameter is the name of the input box for uploading files in the form

//The following 0 means the file name will not be changed. If it is 1, the system will generate a random file name

　if (!$f->run(uploadinput,0)){

// Only the last error message can be obtained through $f->errmsg(),

//Detailed information can be obtained in $f->getInfo().

echo $f->errmsg()."
";

　}

　 //The upload results are stored in the array returnArray. //2cto.com

echo "

";<p> </p>
<p>　　print_r($f->getInfo());</p>
<p>　　echo "</p>

";

　}

　}else{

　?>

2. Create the file class_upload.php with the following code

　

class clsUpload{

　var $saveName;//save name

　var $savePath; // Save path

　var $fileFormat = array(gif,jpg,doc,application/octet-stream);//File format & MIME limitation

　var $overwrite = 0; // Overwrite mode

　var $maxSize = 0;//Maximum bytes of file

　var $ext; // File extension

　var $thumb = 0; // Whether to generate thumbnails

　var $thumbWidth = 130;//Thumbnail width

　var $thumbHeight = 130; // Thumbnail height

　var $thumbPrefix = "_";//Thumbnail prefix

　var $errno;// Error code

　var $returnArray= array();//Return information of all files

　var $returninfo= array(); // Return information for each file

// Constructor

// @param $savePath file save path

// @param $fileFormat file format limit array

// @param $maxSize Maximum file size

// @param $overwriet Whether to overwrite 1 allows overwriting 0 prohibits overwriting

Function clsUpload($savePath, $fileFormat=,$maxSize = 0, $overwrite = 0) {

$this->setSavepath($savePath);

$this->setFileformat($fileFormat);

$this->setMaxsize($maxSize);

$this->setOverwrite($overwrite);

$this->setThumb($this->thumb, $this->thumbWidth,$this->thumbHeight);

$this->errno = 0;

　}

// Upload

// @param $fileInput The name of the input in the webpage Form

// @param $changeName Whether to change the file name

Function run($fileInput,$changeName = 1){

　if(isset($_FILES[$fileInput])){

$fileArr = $_FILES[$fileInput];

　if(is_array($fileArr[name])){//Upload multiple files with the same file domain name

　for($i = 0; $i < count($fileArr[name]); $i++){

　$ar[tmp_name] = $fileArr[tmp_name][$i];

$ar[name] = $fileArr[name][$i];

$ar[type] = $fileArr[type][$i];

$ar[size] = $fileArr[size][$i];

$ar[error] = $fileArr[error][$i];

　$this->getExt($ar[name]);//Get the extension and assign it to $this->ext, it will be updated next time in the loop

　$this->setSavename($changeName == 1 ? : $ar[name]);//Set the save file name

　if($this->copyfile($ar)){

　$this->returnArray[] = $this->returninfo;

　}else{

$this->returninfo[error] = $this->errmsg();

　$this->returnArray[] = $this->returninfo;

　}

　}

return $this->errno ? false : true;
