File handling basics in PHP

PHP file handling refers to the process of reading from, writing to, and manipulating files in the file system using PHP.

In PHP, files can be opened for reading, writing, or both using the fopen() function. Once a file is opened, data can be read from or written to the file using various functions such as fgets(), fwrite(), and fgetcsv().

After a file has been processed, it should be closed using the fclose() function to free up resources and prevent data corruption. Additionally, file permissions and ownership can be modified using functions such as chmod() and chown().

Overall, file handling is an essential aspect of PHP programming for performing tasks such as data storage, logging, and data analysis.
