php read and write files

Get file information:

//打开文件
$file_path = "test.txt";

//获取文件信息

if($fp=fopen($file_path,"r")){
	$file_info = fstat($fp);
	echo "<pre class="brush:php;toolbar:false">";
	print_r($file_info);
	echo "

"; echo "
文件大小是{$file_info['size']}"; echo "
文件上次修改时间".date("Y-m-d H:i:s",$file_info['mtime']); echo "
文件上次访问时间".date("Y-m-d H:i:s",$file_info['atime']); echo "
文件上次change时间".date("Y-m-d H:i:s",$file_info['ctime']); }else{ echo "打开文件失败！"; } //关闭文件 fclose($fp); ".filesize($file_path); echo "
".date("Y-m-d H:i:s",fileatime($file_path)); echo "
".filectime($file_path); echo "
".filemtime($file_path); ?>

Read file information:

<?php
//读取文件
$file_path = "test.txt";
//先判断文件是否存在
if(file_exists($file_path)){
	$fp = fopen($file_path,"a+");
	//读取内容并且输出
	$content = fread($fp,filesize($file_path));
	echo "文件内容是：<br/>";
	$content = str_replace("\r\n", "<br/>", $content);
	echo $content;
}else{
	echo "文件不存在";
}
//关闭文件
fclose($fp);
?>

Easy way to read file information:

<span style="font-size:18px;"><?php
// //读取文件
$file_path = "test.txt";
$contents = file_get_contents($file_path);
$contents = str_replace("\r\n", "<br/>", $contents);
echo $contents;
?></span>

The above introduces PHP reading and writing files, including aspects of content. I hope it will be helpful to friends who are interested in PHP tutorials.
