I tried to use fopen, but I only managed to append content to end of file. Is it possible to overwrite all contents with new content in PHP?

Example 1: Using the open() method to overwrite a file. To overwrite a file, to write new content into a file, we have to open our file in “w” mode, which is the write mode. It will delete the existing content from a file first; then, we can write new content and save it. We have a new file with the name “myFile. txt”.
$fh = fopen( 'filelist. txt', 'w' ); fclose($fh); In clear. php, redirect to the caller page by making use of $_SERVER['HTTP_REFERER'] value.
The PHP fwrite() function is used to write and append data into file. fwrite($fp, ' this is additional text '); fwrite($fp, 'appending data');
The file_put_contents() writes data to a file. This function follows these rules when accessing a file: If FILE_USE_INCLUDE_PATH is set, check the include path for a copy of filename. Create the file if it does not exist. Open the file.
Use file_put_contents()
file_put_contents('file.txt', 'bar'); echo file_get_contents('file.txt'); // bar file_put_contents('file.txt', 'foo'); echo file_get_contents('file.txt'); // foo Alternatively, if you're stuck with fopen() you can use the w or w+ modes:
'w' Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
