提供PHP函數的文件句柄，期望文件路徑

Question

使用PHPExcel，我想從互聯網上讀取文件。 PHPExcel庫似乎只適用於打開本地文件，而不是URL。下面是我的嘗試：

<?php 
require __DIR__ . '/vendor/autoload.php'; 
$string = file_get_contents('http://opendatakit.org/wp-content/uploads/static/sample.xls'); 

$stream = fopen('php://memory','r+'); 
fwrite($stream, $string); 
rewind($stream); 

$objPHPExcel = PHPExcel_IOFactory::load('php://memory'); 

這是我收到的錯誤：

Fatal error: Uncaught exception 'PHPExcel_Reader_Exception' with message 'Could not open php://memory for reading! File does not exist.'

我也試圖通過直接的URL（PHPExcel_IOFactory::load('http://opendatakit.org/wp-content/uploads/static/sample.xls')）。類似的錯誤。

Fatal error: Uncaught exception 'PHPExcel_Reader_Exception' with message 'Could not open http://opendatakit.org/wp-content/uploads/static/sample.xls for reading! File does not exist.'

編輯：也嘗試了臨時文件

$string = file_get_contents('http://opendatakit.org/wp-content/uploads/static/sample.xls'); 

$temp = tmpfile(); 
fwrite($temp, $string); 
fseek($temp, 0); 

$objPHPExcel = PHPExcel_IOFactory::load($temp); 

不同的錯誤這個時候：

Warning: pathinfo() expects parameter 1 to be string, resource given in /project/vendor/phpoffice/phpexcel/Classes/PHPExcel/IOFactory.php on line 224

Warning: file_exists() expects parameter 1 to be a valid path, resource given in /project/vendor/phpoffice/phpexcel/Classes/PHPExcel/Reader/Excel2007.php on line 81

Fatal error: Uncaught exception 'PHPExcel_Reader_Exception' with message 'Could not open Resource id #10 for reading! File does not exist.'

你的想法是好的。但PHPExcel需要一個文件路徑才能正常工作。 您可以使用此樣本嘗試：

$string = file_get_contents('http://opendatakit.org/wp-content/uploads/static/sample.xls'); 

$tmp = tempnam(sys_get_temp_dir(), "FOO"); 
file_put_contents($tmp, $string); 

$objPHPExcel = PHPExcel_IOFactory::load($tmp); 

//Perform all your operations 
// ... 

unlink($tmp);
