Create a File
copy$my_file = 'file.txt';
$handle = fopen($my_file, 'w') or die('Cannot open file: '.$my_file); //implicitly creates file.
The fopen() function is used to open files in PHP.
The first parameter of this function contains the name of the file to be opened and the second parameter specifies in which mode the file should be opened:
The file may be opened in one of the following modes:
|Read only. Starts at the beginning of the file
|Read/Write. Starts at the beginning of the file
|Write only. Opens and clears the contents of file; or creates a new file if it doesn't exist
|Read/Write. Opens and clears the contents of file; or creates a new file if it doesn't exist
|Append. Opens and writes to the end of the file or creates a new file if it doesn't exist
|Read/Append. Preserves file content by writing to the end of the file
|Write only. Creates a new file. Returns FALSE and an error if file already exists
|Read/Write. Creates a new file. Returns FALSE and an error if file already exists
Check end of file - The feof() function checks if the "end-of-file" (EOF) has been reached. The feof() function is useful for looping through data of unknown length. PHP cannot read from files opened in w, a, and x mode! An example -
if (feof($file)) echo "End of file";
