How can the use of file_get_contents() improve the process of reading a file in PHP?

Using file_get_contents() in PHP can improve the process of reading a file by simplifying the code and making it more concise. It eliminates the need to open a file handle, read the file line by line, and close the file handle, reducing the overall complexity of the code. This function allows you to read the entire contents of a file into a string variable with just one line of code.

// Read the contents of a file into a variable using file_get_contents()
$fileContents = file_get_contents('example.txt');

// Output the contents of the file
echo $fileContents;
