File Read [PHP]

[w1ww]

Hello,

Using the file read function

$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');

How can I make it to just read the last 5 lines of the file?

Thank you

$file=file('testFile.php');
$lines=count($file);
$i=$lines-5;
while($i < $file){
echo $file[$i];
$i++;
}

I think that may work, it isn't checked at all though, so there may be errors

$file=file('testFile.php');
$lines=count($file);
$i=$lines-5;
while($i < $file){
echo $file[$i];
$i++;
}

$file = file('file.txt');

foreach($file as $line){
   echo $line;
}

easier :p

easier :p

Yes, but w1ww only wants the last 5 lines, that would display all of them

 

[w1ww]

ahtum,

Thanks for your input but lee101 solution works better, although, using his code I get the text, but I get also:

Fatal error: Maximum execution time of 30 seconds exceeded in 3.php on line 7

what is wrong?

Thank you

 

[lee101]

what are lines 6-8 on 3.php, it sounds like another problem
edit:sorry, i'd wrote the code wrong, use this instead:

 $file=file('testFile.php');
$lines=count($file);
$i=$lines-5;
while($i < $lines){
echo $file[$i];
$i++;
}

 

[w1ww]

It works now

Thank you guys!!

Topic is solved but just my input:

$file = file('testFile.php');

for($i = 0; $i <= 5; $i++)
{
    echo $file[count($file)-$i];
}

Just a little cleaner than using while

edit: Read below :santa:

I know it's solved, too, but:

Matthew, that would show the lines backwards. (I think.)

$file = file('testFile.php');

for ($i = 5; $i >= 0; $i--) {
  echo $file[count($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)
