Search after read a file

[Neopyros]

Hi, i'm new and already with a problem 

 

 

Here's the problem, i've read a file, in this file, i've the same word n times, i need to return the last position of the word and the text below.

 

Ex:

File -

Test

Test

Name

Test

Test

Name

Test

Name

Ok

 

Search for Name

Should return Last position of the word Name and Ok

 

I can't make it return the position of the words found, any ideas?

 

<?php
    $open = @fopen("test.txt", "r");
    $text = fread($open,filesize("test.txt "));
    fclose($open);
    $vetor = explode("\n", $texto);
    print("\n<pre>");
    print_r($vetor);
    print("\n\n\n");
    $size = sizeof($vetor);
    for($i=0;$i<$size;$i++){
if($vetor[$i] == 'Name'){
	print(strpos($vetor[$i]));
}
    }
         
?>

Hi

 

strripos(http://uk2.php.net/manual/en/function.strripos.php) return the last position of of a string

 

also you have two different variable names: $text, and $texto;

 

    $text = fread($open,filesize("test.txt "));

    fclose($open);

    $vetor = explode("\n", $texto);

i would reverse the array first (since you're searching for the last instance of 'Name') and use the key as an indicator of which line it resides on (remembering to add 1, since the first key is 0):

 

<?php
    $open = @fopen("test.txt", "r");
    $text = fread($open,filesize("test.txt "));
    fclose($open);
    $vetor = explode("\n", $text);
    print("\n<pre>");
    print_r($vetor);
    print("\n\n\n");

    $reverse = array_reverse($vetor, TRUE);
    foreach($reverse AS $line => $val)
    {
      if ($val == 'Name')
      {
        echo 'Last instance of "Name" occurs on line '.($line+1);
        break;
      }
    }
?>

 

if you want to keep everything on that line and after, simply use a for() starting at $i = $line and ending at the size of the array.

<?php

$file = "test.txt";
$search = "Name";

/****************************/

$lines = file($file);
$positions = array();

foreach($lines as $lineno => $line) {
if(trim($line) == $search) {
  $positions[] = $lineno;
}
}

sort($positions);
$start = end($positions);

for($i = $start; $i <= (count($lines) - 1); $i++) {
echo "{$lines[$i]}<br />\n";
}

?>

 

Completely untested, let's hope it works!

Darkwinter, a paste it wrong in the php file is all text

 

i would reverse the array first (since you're searching for the last instance of 'Name') and use the key as an indicator of which line it resides on (remembering to add 1, since the first key is 0):

I already try that one, but returns nothig... Just like mine =(

 

Chigley, thanks a lot, it works!

 

Thanks guys for the help

So did I read the instructions right? I thought I misunderstood!

[akitchin]

let's have a rehash of the problem - what code are you CURRENTLY using, and what output are you receiving?

I'm using now the one i posted, the output is nothing

[akitchin]

if you're not receiving any output, then the problem resides in your file opening, because it means you haven't actually read from the file.  remove the @ error suppression, make sure error reporting is turned on, and run it again.  take a look at the errors you receive.

What's wrong with mine? :'(
