PHP Simple HTML DOM lookup

Question

I have been playing around with the PHP simple HTML DOM parser most of the day successfully. I now want to scrape text from a page which does not have clear identifiers down to the lowest level.

I managed to bring it down to:

</pre><pre> </pre><p><strong>De heerlijke Pure Daghappen v</strong><strong>an Bistro Puur</strong></p> <p><strong>Voor de vaste lage prijs van&nbsp;slechts &euro; 8,50 !</strong></p> <p>geserveerd tussen 17:00 uur &amp; 18:30 uur</p> <p>&nbsp;</p> <h2>    <strong>De heerlijke Pure Daghappen voor week 32 zijn:</strong></h2> <p><strong><u>Dinsdag 22 Augustus:</u></strong></p> <p><strong>Gegrilde vakenshaas medaillons met champignonsaus</strong></p> <p>  <strong><u>Woensdag 23 Augustus:</u></strong>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> <p><strong>Gekonfijte scharrelhoen bout met truffelsaus</strong></p> <p>   <strong><u>Donderdag 24 Augustus:&nbsp;</u></strong>&nbsp;&nbsp;</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;<br />  <strong>Gebakken zalmfilet met witte wijnsaus</strong></p> <p>  <strong><u>Vrijdag 25 Augustus;</u></strong></p> <p><strong>In de oven gebakken kabeljauw filet met pesto saus</strong></p> <p>&nbsp;</p> <p>Alle heerlijke Pure Daghappen worden vergezeld door een aardappelgarnituur en een frisse salade.<br />    Daghap is exclusief bijpassende wijn.</p> <p>&nbsp;</p> <p><strong>Wij verwelkomen u graag!</strong></p> <p><em><strong>Team Bistro Puur</strong></em></p> <p class="rteindent1 rtecenter"><strong>&nbsp;</strong></p> an Bistro Puur

by using

$html = file_get_html('http://www.bistropuur.nl/pure-daghappen');
foreach($html->find('div[class=node-content]') as $e){
    $temp = [$e->innertext];
}

I subsequently want to create an array that contains all the different pieces of text to allow further manipulation towards something like:

$data = array[Dinsdag 22 Augustus, Gegrilde vakenshaas medaillons met champignonsaus, ....].

I tried the following:

Questions:

Why am I getting the whole html string again at array[0] ?
How can I quickly remove the remaining , <u>..</ul> tags?
I am obtaining 15 nested arrays. I can work with those but is it possible to remove the nesting from the start?
Can I do all this in a more efficient way?

I updated to code to (based on the feedback from Peter):

$html = str_get_html($str);
foreach($html->find('strong') as $e){
    $temp[] = $e->plaintext;
}

This gives me the correct plain array with all the data. Great!

Answer 1

Why am I getting the whole html string again at array[0]?

Probably because you still have the following line in your code, initializing the $temp -variable with an array with a single element $e->innertext .

$temp = [$e->innertext];

Initialize the $temp variable just before your foreach with $temp = []; .

How can I quickly remove the remaining ,.. tags?

Use $e->plaintext instead of $e->innertext (make sure to read the documentation )

I am obtaining 15 nested arrays. I can work with those but is it possible to remove the nesting from the start?

Because you tell it to create an array everytime (why are you doing that??):

$temp[] = [ $e->innertext ];
          ^ array open    ^ array-close

Use $temp[] = $e->innertext; instead (or plaintext according to previous)

Don't know how you are including html DOM, but using this script:

<?php
include "simple_html_dom.php";
$html = '</pre><pre> </pre><p><strong>De heerlijke Pure Daghappen v</strong><strong>an Bistro Puur<$
$html = str_get_html($html); // create a html DOM object again
foreach($html->find('strong') as $e){ // search for <strong> tag
$temp[] = $e->plaintext; // get the inside of the html tag
}
var_dump_pre($temp);


function var_dump_pre($mixed = null) {
  echo '<pre>';
  print_r($mixed);
  echo '</pre>';
  return null;
}
?>

...will produce this output:

Array
(
    [0] => De heerlijke Pure Daghappen v
    [1] => an Bistro Puur
    [2] => Voor de vaste lage prijs van slechts € 8,50 !
    [3] => De heerlijke Pure Daghappen voor week 32 zijn:
    [4] => Dinsdag 22 Augustus:
    [5] => Gegrilde vakenshaas medaillons met champignonsaus
    [6] => Woensdag 23 Augustus:
    [7] => Gekonfijte scharrelhoen bout met truffelsaus
    [8] => Donderdag 24 Augustus: 
    [9] => Gebakken zalmfilet met witte wijnsaus
    [10] => Vrijdag 25 Augustus;
    [11] => In de oven gebakken kabeljauw filet met pesto saus
    [12] => Wij verwelkomen u graag!
    [13] => Team Bistro Puur
    [14] =>  
)
