① 读出要修改的文件的内容

② 进行修改

③ 将修改后的内容写进文件

index.php:

<?php 
require ‘dir.func.php‘;
require ‘file.func.php‘;
require ‘common.func.php‘;
$path = ‘file‘;
$info = readDirectory($path);

$act = @$_REQUEST[‘act‘];
$filename = @$_REQUEST[‘filename‘];
//跳转变量
$redirect = "index.php?path={$path}";
if($act == ‘createFile‘){
    //创建文件
    $mes = createFile($path.‘/‘.$filename);
    alertMes($mes,$redirect);
}else if($act == ‘showContent‘){
//查看文件内容
    $content=file_get_contents($filename);
    //echo "<textarea readonly=‘readonly‘ cols=‘100‘ rows=‘10‘>{$content}</textarea>";
    //高亮显示PHP代码
    //高亮显示字符串中的PHP代码
    if(strlen($content)){
    $newContent=highlight_string($content,true);
    //高亮显示文件中的PHP代码
    //highlight_file($filename);
    $str=<<<EOF
    <table width=‘100%‘ bgcolor=‘pink‘ cellpadding=‘5‘ cellspacing="0" >
        <tr>
            <td>$newContent</td>
        </tr>
    </table>
EOF;
        echo $str;
    }else{
        alertMes("文件没有内容，请编辑再查看！",$redirect);
    }
}else if($act == ‘editContent‘){
    $content = file_get_contents($filename);
    $str=<<<EOF
    <form action=‘index.php?act=doEdit‘ method=‘post‘>
    <textarea name=‘content‘  cols=‘100‘ rows=‘10‘>$content</textarea></br>
    <input type=‘hidden‘ name=‘filename‘ value=‘{$filename}‘>
    <input type=‘submit‘ value=‘修改文件内容‘>
    </form>
EOF;
    echo $str; 
}else if($act == ‘doEdit‘){
    //修改文件内容
    $content = $_POST[‘content‘];
    if(file_put_contents($filename, $content)){
        $mes = ‘文件修改成功‘;
    }else if(!$content){
        $mes = ‘文件内容被清空‘;
    }else{
