在PHP中将多个文件读取到单个数组中


Reading Multiple Files into a Single Array in PHP

请帮助我了解如何从一个目录中读取多个文件,并将它们合并到PHP中的单个数组中。我已经开发了一个代码,但它不起作用,如下所示:

<?php
$directory = "archive/";
$dir = opendir($directory);
$file_array = array(); 
while (($file = readdir($dir)) !== false) {
  $filename = $directory . $file;
  $type = filetype($filename);
  if ($type == 'file') {
     $contents = file_get_contents($filename);
     $texts = preg_replace('/'s+/', ' ',  $contents);
      $texts = preg_replace('/[^A-Za-z0-9'-'n ]/', '', $texts);
      $text = explode(" ", $texts);
  }
 $file_array = array_merge($file_array,  $text);
}
$total_count = count($file_array);
echo "Total Words: " . $total_count;
closedir($dir);  
?>

但该代码的输出指示"Total Words:0",尽管如此,我在目录中有两个文件,总共占910个单词。

问候,

小错误:

$file_array=array_merge($file_array,  $text);

应该在if块内部,而不是在它外部。您的代码的其余部分也可以。像这个

if ($type == 'file') {
     $contents = file_get_contents($filename);
     $texts = preg_replace('/'s+/', ' ',  $contents);
     $texts = preg_replace('/[^A-Za-z0-9'-'n ]/', '', $texts);
     $text = explode(" ", $texts);
     $file_array = array_merge($file_array,  $text);
  }
