PHP extension php_zip enabled (required if you need PHPExcel to handle .xlsx .ods or .gnumeric files)

3. Fill the facade to the configuration file

app/config/app.config

config/app.php

5. load the file

Excel::load('file.xls', function($reader) {

    // reader methods

});

Note that the file may be stored in a file, or a file transfer by the client through the client file delivery client transfer complete logic and a basic example of the detection of the file is given below:

function checkFileUploadTrue(){
    // UPLOAD_ERR_OK => '文件上传成功。'
            // 下面的错误对应的整数位1-》1
    $error = [
        UPLOAD_ERR_INI_SIZE => '上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值。',//1
        UPLOAD_ERR_FORM_SIZE => '上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值。',//2
        UPLOAD_ERR_PARTIAL => '文件只有部分被上传。',//3
        UPLOAD_ERR_NO_FILE => '没有文件被上传。',//4
        UPLOAD_ERR_NO_TMP_DIR => '找不到临时文件夹。',//6
        UPLOAD_ERR_CANT_WRITE => '文件写入失败。'//7
    ];
    // 检测error是否为0，其他的任务不成功
    if ($_FILES['file']['error'] !== UPLOAD_ERR_OK) {
        return ['flag'=> False,'msg' => $error[$_FILES['file']['error']]];
    }
    // 检测是否为上传文件
    if (!is_uploaded_file($_FILES["file"]["tmp_name"])) {
       return ['flag' => False, 'msg' => '不是上传的文件！'];
    }
    // 检测是否为约定的文件类型
    $file_type = ['application/vnd.openxmlformats-officedocument.spreadsheetml.sheet','application/vnd.ms-excel'];
    if (!in_array($_FILES['file']['type'],$file_type)) {
        return ['flag' => False, 'msg' => '只能上传excel类型文件'];
    }
    // 目录
    $storage_file_dir = '/data/file/tmp/';
    //转存文件
    $tmp_filename = $_FILES['file']['tmp_name'];
    $dest_filename = $storage_file_dir.$_FILES['file']['name'];
    if(!move_uploaded_file($tmp_filename,$dest_filename)){
        return ['flag' => False, 'msg' => '文件转存失败，确认之后再转存！'];
    }
    return ['flag'=> True,'msg' => ''];
}

6. read the contents of a file, you can use two ways

Excel::load('local_store.xls', function($reader) {

})->get();

//或者

Excel::load('local_store.xls', function($reader) {

    // 获取所有的结果集
    $results = $reader->get();

    //或者使用all
    //$results = $reader->all();

});
