　　本文标签：php,编辑,保存,文件

本文实例讲述了php实现编辑和保存文件的方法 。分享给大家供大家参考 。具体如下：

save_file.php：

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

read_file.php：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<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>

希望本文所述对大家的php程序设计有所帮助 。
