PHP: How Do I Read From a Text File?

How do I read from text file using PHP under Linux or UNIX?

PHP does supports the file reading and writing. You can open a file using the fopen() function. Once the file is open, you can use the fgets() function to read from the file.

For example, if you wish to open file called /tmp/file1.txt then following PHP code will help you to read file. fopen() will open fine in r (read) mode. Then while loop will open file using fgets() function till end of file:

php source code

<html>
<head>
<title>File read demo</title>
</head>
<body>
<?php
$file = "/tmp/file1.txt";
$f = fopen($file, "r");
while ( $line = fgets($f, 1000) ) {
print $line;
}
?>
</body>
</html>

See fopen() and fgets() for more information.

  6. This works for me:

    if ($_FILES['fileUpload']['error'] == UPLOAD_ERR_OK               
      && is_uploaded_file($_FILES['fileUpload']['tmp_name'])) { 
  echo("<pre>");
  echo file_get_contents($_FILES['fileUpload']['tmp_name']); 
  echo("</pregt;");

    Edited by admin: added pre tags.

    1. Well, use the pre tags to display the variable with file contents with print. Obove example posted a bit weird.
