This article mainly introduces the operations of PHP for reading, editing and saving files. Interested friends can refer to it. I hope it will be helpful to everyone.

The example in this article describes the method of editing and saving files in PHP, as follows:

save_file.php：

<?php 
session_start(); 
$handle = fopen($_POST[&#39;original_file_name&#39;], "w"); 
$text = $_POST[&#39;file_contents&#39;]; 
if(fwrite($handle, $text) == FALSE){ 
  $_SESSION[&#39;error&#39;] = &#39;<span class="redtxt">There was an error</span>&#39;; 
}else{ 
  $_SESSION[&#39;error&#39;] = &#39;<span class="redtxt">File edited successfully</span>&#39;; 
} 
fclose($handle); 
header("Location: ".$_POST[&#39;page&#39;]); 
?>

read_file.php：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>
<form action="savecontents.php" method="post">
<textarea name="file_contents" style="width:700px;height:600px;">
<?php 
$fileName = "location/of/orignal/file/my_file.php"; 
$handle = fopen($fileName, "r"); 
while (!feof($handle)){ 
  $text = fgets($handle); 
  echo $text; 
} 
?> 
</textarea>
<input type="hidden" value=" <? echo $fileName; ?> " name="original_file_name" />
</form>
<body>
</body>
</html>
