Question

Fill in the blanks to open a file and output its contents if the file exists. Otherwise, output the corresponding error message. if File.file?("demo.txt")
f=file.open("demo.txt")
puts f.
f.close
else
end

Answer 1

you can use different method to open a file and read its content if it exists. But for this I can give you;
<?php
$file = "demo.txt";

$handle = fopen($file, "r");
if(file_exists($file){
$cont = fread( $handle, filesize($file) );

echo $cont;
}else{
echo "your error msg";
}

fclose($handle);

?>
you might surround it with try catch block and handle your exception.
