How Can I nest two foreach to get right values output? - php

Question

I have two foreach blocks to get some values from a web page (I'm scraping values from an HTML table).
<?php
include('../simple_html_dom.php');
$html = file_get_html('http://www.betexplorer.com/soccer/belgium/jupiler-league/results/');
foreach($html->find('td') as $e) {
echo $e->innertext . '<br>';
}
foreach( $html->find('td[data-odd]') as $td ) {
echo $td->attr['data-odd'].PHP_EOL;
}
?>
and this is my HTML code:
<tr class="strong">
<td class="first-cell tl">
Waasland-Beveren - Anderlecht
</td>
<td class="result">
1:0
</td>
<td class="odds best-betrate" data-odd="5.97"></td>
<td class="odds" data-odd="4.21"></td>
<td class="odds" data-odd="1.51"></td>
<td class="last-cell nobr date">21.02.2016</td>
</tr>
<tr class="">
<td class="first-cell tl">
Waregem - KV Mechelen
</td>
<td class="result">
2:3
</td>
<td class="odds" data-odd="1.83"></td><td class="odds" data-odd="3.71"></td>
<td class="odds best-betrate" data-odd="3.99"></td>
<td class="last-cell nobr date">21.02.2016</td>
</tr>
In this way, in my output, I get before values from the first foreach and, after, values from the second. I'd like to get values together in the right order. For example:
21.02.2016 Waasland-Beveren - Anderlecht 1:0 5.96 4.20 1.51
21.02.2016 Waregem - KV Mechelen 2:3 1.83 3.71 3.98

Answer 1

If they have the exact (count) or (length). Use the normal for after you assign them to two variables.
$td = $html->find('td');
$attr = $html->find('td[data-odd]');
for($i=0; $i < count($td); $i++)
echo $td[$i]->innertext."<br/>".$attr[$i]->attr['data-odd'].PHP_EOL;
Update:
You want to reorder the tds you received from the HTML file, that means you have to think of another logic in how to retrieve them. This updated code is very specific to your case:
$match_dates = $html->find("td[class=last-cell nobr date]"); // we have 1 per match
$titles = $html->find("td[class=first-cell tl]"); // 1 per match
$results = $html->find("td[class=result]"); // 1
$best_bets = $html->find("td[class=odds best-betrate]"); // 1
$odds = $html->find("td[class=odds]"); // 2
// Now to output everything in whatever order you want:
$c=0; $b=0; // two counters
foreach($titles as $match)
echo $match_dates[$c]->innertext." - ".$match->innertext." [".$results[$c]->innertext."] - Best bet rate: ".$best_bets[$c++]->attr['data-odd']." - odds: ".$odds[$b++]->attr['data-odd'].", ".$odds[$b++]->attr['data-odd']."<br/>";
