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。
