File Read [PHP]
Hello,
Using the file read function
PHP Code:
$myFile = "testFile.txt" ;
$fh = fopen ( $myFile , 'r' );
How can I make it to just read the last 5 lines of the file?
Thank you

PHP Code:
$file = file ( 'testFile.php' );
$lines = count ( $file );
$i = $lines - 5 ;
$i < $file ){
$file [ $i ];
$i ++;
I think that may work, it isn't checked at all though, so there may be errors

$file as $line ){
$line ;

ahtum,
Thanks for your input but lee101 solution works better, although, using his code I get the text, but I get also:
PHP Code:
Fatal error : Maximum execution time of 30 seconds exceeded in 3.php on line 7
what is wrong?
Thank you

what are lines 6-8 on 3.php, it sounds like another problem
edit:sorry, i'd wrote the code wrong, use this instead:
PHP Code:
$file = file ( 'testFile.php' );
$lines = count ( $file );
$i = $lines - 5 ;
$i < $lines ){
$file [ $i ];
$i ++;

Topic is solved but just my input:
PHP Code:
$file = file ( 'testFile.php' );
$i = 0 ; $i <= 5 ; $i ++)
$file [ count ( $file )- $i ];
Just a little cleaner than using while

I know it's solved, too, but:
Matthew, that would show the lines backwards. (I think.)
PHP Code:
$file = file ( 'testFile.php' );
$i = 5 ; $i >= 0 ; $i --) {
$file [ count ( $file )- $i ];
I don't know if that would work because count returns the number of items but that is one higher than the arrays highest key (if you can understand what I'm trying to say.) You might have to start with $i as 6 and just do $i > 0; :x

Ahh good point Dan. That didn't even enter my head
(p.s. Your example is correct)
