In PHP, writing to a file can be done using several built-in functions, each suited for different scenarios depending on whether you want to overwrite, append, or write specific parts of the file.
- It is essential for creating logs, saving user data, generating reports, and more.
The following built-in functions in PHP’s library can help us perform the write operation:
- fwrite()
- fputs()
fwrite()
The fwrite() function is one of the most commonly used functions to write data to a file. It writes data to a file pointer, which allows more control over file access modes (writing at the beginning, appending to the end, etc.).
Syntax:
fwrite(resource $file, string $data, int $length = null): int|false
