fopen

php 创建文件的方法有很多种我们最常用的就是fopen,file_put_contents这两种方法来创建文件了,下面我来给大家详细介绍介绍,有需要了解的同学可参考。

创建php文件

 代码如下 复制代码

$str="";
file_put_contents('test.php',$str);//使用脚本创建一个php文件
?>

例2

 代码如下 复制代码

if ($argc != 2) {
die("Usage: php mkphp.php filename");
}
array_shift($argv);
$cat= $argv[0];
file_put_contents($cat.".php", "

?>");

利用fopen创建文件

 代码如下 复制代码

$fp=fopen("1.txt","w+");//fopen()的其它开关请参看相关函数
$str="我加我加我加加加";
fputs($fp,$str);
fclose($fp);
?>

上面没作任何考虑,如果要全面点我们首先,确定你所要新建文件所在的目录权限; 建议设备为777。然后,新建文件的名称建议使用绝对路径。

 代码如下 复制代码

$filename="test.txt";
$fp=fopen("$filename", "w+"); //打开文件指针,创建文件
if ( !is_writable($filename) ){
      die("文件:" .$filename. "不可写,请检查!");
}
//fwrite($filename, "anything you want to write to $filename.";
fclose($fp);  //关闭指针

'r' 开文件方式为只读,文件指’指到开始处
'r+' 开文件方式为可读写,文件指’指到开始处
'w' 开文件方式为写入,文件指’指到开始处 并将原文‘的长度设为 0。若文件不存在‘‘建立新文件–
'w+' 开文件方式为可读写,文件指’指到开始处 并将原文‘的长度设为 0。若文件不存在‘‘建立新文件–
'a' 开文件方式为写入,文件指’指到文件最后。若文件不存在‘‘建立新文件–
'a+' 开文件方式为可读写,文件指’指到文件最后。若文件不存在‘‘建立新文件–
'b' 若操作系统的文字及二进位文件不同,‘可以用“‘”,UNIX 系统不–要“用 参”。

 代码如下 复制代码

///创建文件
function creat_file($PATH){
   $sFile = "test.html";
   if (file_exists($PATH.$sFile)) {
    creat_file();
   } else {
    $fp= fopen($PATH.$sFile,"w");
    fclose($fp);
   }
   return $sFile;
}
