PHP fget: read a file line by line

To get only one line of a text file, or get line by line, we have to use fget() php function instead of fread() .

We saw in the previous lesson, that if you want to read a file, you can open it and put all it's content in some variable. But in this script we will see how to get the data from the file line by line until the end of file is reached:

<?php

$filename = 'myfile.txt' ;

$file = fopen($filename , 'r' ) or exit ( "Enable to open file");

while(!feof($file))
{
echo fgets($file) . "<br />" ;
}

?>

Why to use this script:
Let's say you have a text file with many line:

----myfile.txt------
Hello Word.
We love PHP !
Here are great tutorials
And scripts and codes !
--------------------

if you use this script

$contents = fread($handle, filesize($filename));
echo $contents;

This will show:

Hello Word.We love PHP !Here are great tutorialsAnd scripts and codes !

And this is beacuse HTML script don't understand the new line character, so you need to create a new line with "<br />".

So we have to use:

<?php

$filename = 'myfile.txt' ;

$file = fopen($filename , 'r' ) or exit ( "Enable to open file");

while(!feof($file))
{
echo fgets($file) . "<br />" ;
}

?>

Display:

Hello Word.

Here are great tutorials
And scripts and codes !
