使用PHPEXCEL读取网络文件

Jun 23, 2016 pm 02:19 PM

读取本地文件没问题。换成读取web文件
Could not open xxx.xls for reading! File does not exist.

file_exists报错。 如果改成file_get_contents()  取出的数据又不正常。求解决方案

他本身就是用 file_get_contents 的

        public function read($sFileName)        {                // Check if file exists and is readable                if(!is_readable($sFileName)) {                        throw new Exception("Could not open " . $sFileName . " for reading! File does not exist, or it is not readable.");                }                // Get the file data                $this->data = file_get_contents($sFileName);
Copy after login

老大。
是先 
if (!file_exists($pFilename)) {
throw new PHPExcel_Reader_Exception("Could not open " . $pFilename . " for reading! File does not exist.");
}

这里就报错  我加了句 !file_exists($pFilename) && ! file_get_contents('xxx')

这里不报错了 。
紧接着下面执行
$ole = new PHPExcel_Shared_OLERead();

// get excel data
$res = $ole->read($pFilename);

这里是read方法
if(!is_readable($sFileName)) {
throw new PHPExcel_Reader_Exception("Could not open " . $sFileName . " for reading! File does not exist, or it is not readable.");
}

这里就又报错了。没看到$this->data = file_get_contents($sFileName); 请问这个在哪 没搜到。。莫非版本改了?

不错,我说的 file_get_contents 不就在你第二处报错的下面吗?

file_get_contents 可以安全的处理二进制文件,所以可以用 file_get_contents 读取excel文件

但如果是远程读取的话,由于网络和对方的原因,失败的概率还是蛮大的
还是应该先读回到本地临时文件比较稳妥

哎。看来要改代码了。PHPExcel能直接读取成数组处理。 用file_get_contents只能搞成字符串。 在逻辑处理上全部都要改正

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
