Opening and Reading Files in PHP

What does the following PHP code do? $fh = fopen(' ', 'r'); while( !feof($fh) ){ $line = fgets($fh); echo $line; } The given PHP code opens a file, reads it line by line, and prints the contents of the file on the screen.

Explanation:

The PHP code provided:
$fh = fopen(' ', 'r');
while( !feof($fh) ){
$line = fgets($fh);
echo $line;
}

Here is a detailed explanation of how the PHP code works:

The code opens a file and assigns a handle to the file with the `fopen()` function. In this case, a file is opened in read mode with a filename specified within single quotes and assigned the value to the `$fh` variable.

Next, the `while()` loop checks the condition of the end of the file using the `!feof($fh)` function. The loop continues until the end of the file is reached.

Each line of the file is then read into the `$line` variable using the `fgets($fh)` function. The code block then prints the `$line` on the screen with the `echo` statement.

Therefore, the PHP code opens a file, reads it line by line, and prints the contents of the file on the screen.
