This should work:
<?php
$fp = "path/to/myfile.txt"; // The path to our file
$file_array = file($fp); //This reads the contents of our file into an array
for($i = 0; $i < count($file_array); $i++) // Iterate through the contents of $file_array and display each line
{
if($i == 0)
{
echo $file_array[$i];
echo "Blah, blah, blah, blah." // This would be your text between the first and second line.
}
while(($i >= 1) && ($i <= 3))
{
echo $file_array[$i];
}
if($i == 4)
{
echo "Blah, blah, blah, blah." // This would be your text after lines 2-4
echo $file_array[$i];
}
}
?>
