[SOLVED] Read line of file

[evank3]

Is it possible to just read a certain line of a file and put it into the output?  If it took out html codes that would be nice, but it doesn't need to.  all I need to do is read a certain line of a external site like www.example.com

the link you gave was a faulty one, if you just want to read one line of a text file:

$contents = file("text.txt");
echo $contents[0];//this would give you line one
echo $contents[4];//this would give you line five
echo $contents[99];//this would give you line one hundred
echo "and so on";//ignore this

Is this what you are looking for?

Well sort of, but I meant to read an external file from another website.  like when you do view source on a page but only grabbing a certain line

I dont think include and require can get the contents of foreign pages, but I think file_get_contents() might work.

I cant find any related articles in google, please try and tell me the results.

Its almost working perfectly!  the only problem is that its reading the characters in the file not lines.  like the code you gave me gave me the first, fifth, and ninty-ninth character in the file instead of giving me certain lines.

 

Here is my code:

<php
file_get_contents("URL OF WEBPAGE");
echo $contents[0];//this would give you line one
echo "<br>";
echo $contents[4];//this would give you line five
echo "<br>";
echo $contents[99];//this would give you line one hundred
?>

http://us3.php.net/file_get_contents

"Identical to file(), except that file_get_contents() returns the file in a string,"

explode the string using \n.

 

Strings, when used like an array return the character at that position.

 

So $content=file_get_contents($url);

 

$lines=explode("\n", $content);

$lines[0] //Line 1 etc
