如何从文本文件中的行动态创建文件

Question

How can I use PHP to loop through a text file and create file xxx.txt base of the text of each line?

For example I have a file named files.txt and it contains

files.txt

red 
pink 
purple 
deep purple 
indigo 
blue 
light blue 
cyan 
teal 
green 

I already tried this

<?php
$file = fopen("files.txt","r");

while(! feof($file))
  {
  echo fgets($file). "<br />";
  $fileName = fgets($file);
  $myfile = fopen($fileName.'.txt, "w");

  }

fclose($file);
?> 

but this only create last green.txt.

Answer 1

$handle = fopen("path/to/files.txt", "r");
$filesToCreate = [];
if ($handle) {
    while (($line = fgets($handle)) !== false) {

        // you may need to add the full path here..
        $filesToCreate[] = $line . '.txt';
    }

    fclose($handle);
} else {
    // error opening the file.
}

foreach ($filesToCreate as $newFile) {
    $createdFile = fopen($newFile, 'w');
    fclose($createdFile);
}
