从CSV/TXT文件看PHP中的关联数组

您可以避免这些循环、条件和 fopen() fclose() 混乱:

<?php
// read the file into an array
$arr = file("data.csv", FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);

// split each line at the comma
array_walk($arr, function(&$v, $k){$v=explode(",", $v);});

// build an array from the data
$keys = array_column($arr, 0);
$values = array_column($arr, 1);
$logins = array_combine($keys, $values);

$logins = array();
$file_handle = fopen("data.csv", "r");
while (!feof($file_handle) ) {
  $line_of_text = fgetcsv($file_handle, 1024);
  // At this point, $line_of_text is an array, which will look
  // something like this: {[0]=>'user1',[1]=>'1234'}
  if (empty($line_of_text)) { break; }
  $logins[$line_of_text[0]] = $line_of_text[1];
  // So the line above is equivalent to something like
  // $logins['user1'] = '1234';
}

这可能也会奏效,尽管我认为这不是你真正想进入的领域

/* $dataFile = fopen("data.txt", "r"); */
$dataFile = file_get_contents("data.txt");
/* logins = array($dataFile); */
eval('$logins = ' . $dataFile . ';');
