Getting values from webpage using Simple HTML Dom library

Question

I'm trying to get values from a table in a webpage and for that I'm using Simple HTML Dom library. This is how my code looks like:

include('simple_html_dom.php');

$html = file_get_html('http://www.lvbp.com/posicion.html');

$arr = array();
foreach ($html->find('tr') as $e) {
    array_push($arr, $e->innertext);
}

echo '<pre>';
print_r($arr);
echo '</pre>';

for ($i = 2; $i < count($arr); $i++) {
    str_replace("", "-", $arr[$i]);
    print_r($arr[$i]);
}

And I get this as output when print_r($arr):

Array
(
    [0] =>       EQUIPOS      J      G      P      Vent    
    [1] => 
    [2] =>       Navegantes      11      8      3      0    
    [3] =>       Tigres      11      8      3      0    
    [4] =>       Caribes      11      6      5      2    
    [5] =>       Leones      11      6      5      2    
    [6] =>       Aguilas      11      5      6      3    
    [7] =>       Tiburones      10      4      6      3.5    
    [8] =>       Cardenales      10      3      7      4.5    
    [9] =>       Bravos      11      3      8      5    
)

But from here I need to get separately meaning "Navegantes", "11", "8" and so on ... for each array position. For that my last code:

for ($i = 2; $i < count($arr); $i++) {
    str_replace("", "-", $arr[$i]);
    print_r($arr[$i]);
}

But it's not working since I get this as result:

Navegantes 11 8 3 0 Tigres 11 8 3 0 Caribes 11 6 5 2 Leones 11 6 5 2 Aguilas 11 5 6 3 Tiburones 10 4 6 3.5 Cardenales 10 3 7 4.5 Bravos 11 3 8 5

What I'm missing? Any help?

UPDATE

This is how my code looks like based on suggestions:

include('simple_html_dom.php');
$html = file_get_html('http://www.lvbp.com/posicion.html');

$arr = array();
foreach ($html->find('tr') as $e) {
    $narr = array();
    foreach ($e->find('td') as $vp) {
        array_push($narr, $vp->plaintext);
    }
    $arr[] = array($narr);
}

Use $arr[$i]=str_replace("", "-", $arr[$i]); instead of str_replace("", "-", $arr[$i]); — Subin

Are you trying to get each values of td in a tr as an array ? — Subin

Try this :

$arr = array();
foreach ($html->find('tr') as $e) {
 $narr=array();
 foreach($e->find('td') as $vp){
  array_push($narr,$vp->plaintext);
 }
 $arr[]=array($narr);
}

instead of :

foreach ($html->find('tr') as $e) {
    array_push($arr, $e->innertext);
}

And drop the code :

for ($i = 2; $i < count($arr); $i++) {
    str_replace("", "-", $arr[$i]);
    print_r($arr[$i]);
}

You will get an array with keys as tr tags and their values as each td of tr.

No, you're wrong I get this error:

PHP Fatal error:  Call to a member function find() on a non-object in /var/www/html/reader/parser/posicion.php on line 29, referer: http://devserver/reader/parser/

where line 29 is foreach($code->find('td') as $vp){ ...

Are you sure you replaced correctly ? Because on my side it's working.

Here's an aproach:

// includes Simple HTML DOM Parser
include "simple_html_dom.php";

$url = "http://www.lvbp.com/posicion.html";

//Create a DOM object
$html = new simple_html_dom();
// Load HTML from a string
$html->load_file($url);

// parse rows
foreach ($html->find('tr') as $i => $row) {

    // Skip the second empty row
    if ($i == 1)
        continue;

    // parse and print cells
    foreach ($row->find('td') as $j => $col) {
        echo $col->plaintext;
        echo "|";
    }
    echo "<hr>";
}


// Clear DOM object (needed essentially when using many)
$html->clear(); 
unset($html);
