php实现编辑和保存文件的方法

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。
