Fopen (php) from remote server works only for reading
I need to open a text file from a remote server and to write some information in it, using PHP fopen().,You can only create new files using this method; if you try to overwrite a file that already exists, the fopen() call will fail.,Though this will be all quite inefficient, as you will be opening whole FTP session twice. Once for reading and once for writing. You better use FTP functions ftp_get and ftp_put over one session.,You might get the idea from the example above that you can use this technique to write to a remote log file. Unfortunately that would not work because the fopen() call will fail if the remote file already exists. To do distributed logging like that, you should take a look at syslog().
Additionally, FTP URL wrapper does not allow overwriting of an existing file by default, you need to enable it using
overwrite FTP context option.
$context = stream_context_create(['ftp' => ['overwrite' => true]]); $fh = fopen($filename, 'w', false, $context);
The mode parameter specifies the type of access you require to the stream. It may be any of the following: , On the Windows platform, be careful to escape any backslashes used in the path to the file, or use forward slashes. , If you use the wrong line ending characters when writing your files, you might find that other applications that open those files will "look funny". ,popen() - Opens process file pointer
Pass the file's URL to fopen( ): ,When fopen( ) is passed a filename that begins with http://, it retrieves the given page with an HTTP/1.0 GET request (although a Host: header is also passed along to deal with virtual hosts). Only the body of the reply can be accessed using the file handle, not the headers. Files can be read, not written, via HTTP. ,When fopen( ) is passed a filename that begins with ftp://, it returns a pointer to the specified file, obtained via passive mode FTP. You can open files via FTP for either reading or writing, but not both. , You want to open a file that's accessible to you via HTTP or FTP.
$fh = fopen('http://www.example.com/robots.txt', 'r') or die($php_errormsg);
The ftp:// handler only allows creating new files with fopen("ftp://...", "w");.,I'm making a script to open remote file (ftp) and edit it with fopen and fwrite.I have problem while connecting to ftp.I made this code,If the file already exists you can only write to it if you open it with overwriting set, i.e mode w+.,al variables are set.I tried with ftp://... in web page and it works.allow_url_fopen is On... It just says "ftp error"
I'm making a script to open remote file (ftp) and edit it with fopen and fwrite.I have problem while connecting to ftp.I made this code
$handle = fopen("ftp://".$ftp['username']. ":".$ftp['password']. "@".$ftp['server']. "/cstrike/addons/amxmodx/configs/users.ini", "w") or die("ftp error"); fwrite($handle, $text. "n") or die('err2.');
“r+”: It represents Read/Write.It starts at the beginning of the file.,PHP | fread( ) Function,“a+”: It represents Read/Write. It preserves the file’s content by writing to the end of the file.,“r”: It represents Read only. It starts at the beginning of the file.
resource fopen($file, $mode, $include_path, $context)
File does not exist!
