What are the different parameters available for the fopen function in PHP?

The fopen function in PHP is used to open a file or URL for reading or writing. There are different parameters available for the fopen function that allow you to specify the mode in which the file should be opened, such as 'r' for reading, 'w' for writing, 'a' for appending, 'x' for creating and writing to a new file, and more. You can also specify additional parameters like 'b' for binary mode, 't' for text mode, and 'e' for setting the close-on-exec flag. 

// Example of using the fopen function with different parameters
$file = fopen("example.txt", "r"); // opens the file for reading
$file = fopen("example.txt", "w"); // opens the file for writing
$file = fopen("example.txt", "a"); // opens the file for appending
$file = fopen("example.txt", "x"); // creates and opens the file for writing
$file = fopen("example.txt", "rb"); // opens the file for reading in binary mode
$file = fopen("example.txt", "wt"); // opens the file for writing in text mode
$file = fopen("example.txt", "ae"); // opens the file for appending and sets the close-on-exec flag
