83 php文件

---

1.打开文件

<code><span><span><?php </span><span>//1.文件信息</span><span>//打开文件</span><span>$file_path</span> = <span>'./file/test.txt'</span>;
<span>$fp</span> = fopen(<span>$file_path</span>,<span>'r'</span>);

<span>if</span>(<span>$fp</span>){
    <span>$file_info</span> = fstat(<span>$fp</span>);
    var_dump(<span>$file_info</span>);
    <span>echo</span> date(<span>"Y-m-d H:i:s"</span>,<span>$file_info</span>[<span>'mtime'</span>]) . <span>'<br>'</span>;
    <span>echo</span> date(<span>"Y-m-d H:i:s"</span>,<span>$file_info</span>[<span>'atime'</span>]) . <span>'<br>'</span>;
    <span>echo</span> date(<span>"Y-m-d H:i:s"</span>,<span>$file_info</span>[<span>'ctime'</span>]) . <span>'<br>'</span>;
}<span>else</span>{
    <span>echo</span><span>'打开文件失败'</span>;
}

fclose(<span>$fp</span>);

<span>echo</span> filemtime(<span>$file_path</span>) . <span>'<br>'</span>;
<span>echo</span> fileatime(<span>$file_path</span>) . <span>'<br>'</span>;
<span>echo</span> filectime(<span>$file_path</span>) . <span>'<br>'</span>;</span></span></code>

2.读文件

<code><?php //<span>1.文件信息

//打开文件
<span>$file_path</span> = <span>'./file/test.txt'</span>;

//****第一种读取方式******
/*<span>if</span>(file_exists(<span>$file_path</span>)){
    <span>$fp</span> = fopen(<span>$file_path</span>,<span>'a+'</span>);
    //读内容，并输出

    <span>$con</span> = fread(<span>$fp</span>,filesize(<span>$file_path</span>));
    //在默认情况下，我们得到的内容输出到网页后，不会换行
    //因为网页不会识别 \r\n 是换行符，要把 \r\n 替换成 <br>
    <span>$con</span> = str_replace(<span>"\r\n"</span>,<span>"<br>"</span>,<span>$con</span>);
    <span>echo</span><span>$con</span>;
}<span>else</span>{
    <span>echo</span><span>'文件不存在'</span>;
}

fclose(<span>$fp</span>);*/

//**********第二种读取方式**********
/*<span>$con</span> = file_get_contents(<span>$file_path</span>);
<span>$con</span> = str_replace(<span>"\r\n"</span>,<span>"<br>"</span>,<span>$con</span>);
<span>echo</span><span>$con</span>;*/

//**********第三种读取方式，循环读取，对付大文件**********

<span>$fp</span> = fopen(<span>$file_path</span>,<span>'r'</span>);
//我们设置一次读取<span>1024</span>个字节
<span>$buffer</span> = <span>1024</span>;
//一边读，一边判断是否到达文件末尾
<span>while</span>(!feof(<span>$fp</span>))
{
    <span>$str</span> = fread(<span>$fp</span>,<span>$buffer</span>);
    <span>echo</span><span>$str</span>;
}

fclose(<span>$fp</span>);</code>
