PHP File Handling

PHP file handling involves performing operations on files, such as reading from or writing to them.

1.File Operations:

PHP provides a set of functions for handling files, allowing developers to perform various operations, including reading, writing, creating, deleting, and manipulating files.

2.File Access Modes:

When working with files, developers specify the mode in which the file should be accessed. Common access modes include:

Read (r): Open the file for reading.

Write (w): Open the file for writing. If the file already exists, its content is truncated.

Append (a): Open the file for writing, and if the file exists, move the file pointer to the end.

Binary Mode (b): Used in combination with the above modes for binary file handling.

3.File Pointers:

When a file is opened, PHP maintains a file pointer that keeps track of the current position within the file.

​ The file pointer is moved during read and write operations.

4.Reading from Files:

PHP provides functions like fread(), fgets(), and file() for reading from files.

Developers can read the entire content of a file or read it line by line.

5.Writing to Files:

​Writing to files is done using functions such as fwrite() and file_put_contents().

Developers can write new content to a file or append content to an existing file.
