Q: How can I combine these two foreach loop - php

Question

I have a simple html dom query which read informations from a football fixtures source, and I loading also a json source.
Here is my full code:
<?php
header('Content-Type: text/html; charset=utf-8');
ini_set("user_agent", "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.60 Safari/537.17");
include_once('simple_html_dom.php');
ini_set('display_errors', true);
error_reporting(E_ALL);
$str = file_get_contents('general.json');
$json = json_decode($str,true);
$filename = "source.html";
$html = file_get_html($filename);
class matches {
var $day;
var $kickofftime;
var $result;
function matches ($day, $kickofftime, $tip){
$this->day=$day;
$this->kickofftime=$kickofftime;
$this->result=$result;
return $this;
}
}
$i=0;
$day=$html->find('h1',0);
$day->plaintext;
$day=str_replace("<h1>TODAY FOOTBALL FIXTURES: ","", $day);
$day=str_replace("</h1>","", $day);
$matchday = str_replace(array('MONDAY ', 'TUESDAY ', 'WEDNESDAY ', 'THURSDAY ', 'FRIDAY ', 'SATURDAY ', 'SUNDAY '), '', $day);
$matchday=str_replace(" ","-", $matchday);
$matchday=date('Y-m-d', strtotime($matchday));
foreach($html->find('table.fixtures') as $matches)
{
foreach ($matches->find('tr[class=a1],tr[class=a2]') as $matchesTR) {
$kickofftime=$matchesTR->find('td[class=a11],td[class=a21]',0)->plaintext;
$kodate = date('Y-m-d H:i:s', strtotime("$matchday $kickofftime +1 hour"));
$result=$matchesTR->find('td');
echo $kodate;
echo $result[6]->plaintext.'<br>' ;
$i++;
}
}
//Here is the 2nd foreach with the data of JSON source:
foreach($json as $key => $value) {
$value = json_decode($value, true);
echo $value["country"] . ", " . $value["competition"] . " " . $value["club"] . "<br>";
}
// clean up memory
$html->clear();
unset($html);
?>
The current results from the simple html dom html source:
2014-12-23 20:00:00 2-1
2014-12-23 11:00:00 3-1
2014-12-26 08:00:00 1-1
The result from the JSON source:
America Copa America Boca Juniors
Europe Bundesliga Hannover
Asia JLeague Nagoya
I would like to combine these two results in one foreach and I would like to get this result:
2014-12-23 20:00:00 2-1 America Copa America Boca Juniors
2014-12-23 11:00:00 3-1 Europe Bundesliga Hannover
2014-12-26 08:00:00 1-1 Asia JLeague Nagoya
I hope that there is some expert who can help for me because I tried a lot of variation but without result. I got some advice (with code) from experts, but there was everytime errors. With my code there is no error, but I need other solution because I would like to put all variables to one foreach. Many thanks, I hope that somebody could help me with code, because I am not on high level at php. Thanks again!
I would like to put the two foreach into one foreach, but I don't want to create a new array because I not need.

Assuming you will always have the same amount of items in each and that they match 1 to 1, 2 to 2, you can do this:
$htmlDates = array();
$jsonLeag = array();
foreach($html->find('table.fixtures') as $matches) {
foreach($matches->find('tr[class=a1],tr[class=a2]') as $matchesTR) {
$kickofftime=$matchesTR->find('td[class=a11],td[class=a21]',0)->plaintext;
$kodate = date('Y-m-d H:i:s', strtotime("$matchday $kickofftime +1 hour"));
$result=$matchesTR->find('td');
//echo $kodate;
//echo $result[6]->plaintext.'<br>' ;
$htmlDates[] = $kodates;
}
}
//Here is the 2nd foreach with the data of JSON source:
foreach($json as $key => $value) {
$value = json_decode($value, true);
//echo $value["country"] . ", " . $value["competition"] . " " . $value["club"] . "<br>";
$jsonLeag[] = $value["country"] . ", " . $value["competition"] . " " . $value["club"];
}
if(count($htmlDates) < count($jsonLeag)){
for($i=0;$i<count($htmlData);$i++){
echo $htmlData[$i] . " " . $jsonLeag[$i] . "<br />\r\n";
}
} else {
for($i=0;$i<count($jsonLeag);$i++){
echo $htmlData[$i] . " " . $jsonLeag[$i] . "<br />\r\n";
}
}
Since you have the nested list first and nothing ties the two data sets together, there is no simple way to run one loop and get the data from both. It's easier to push the data you want into an array for each set, and then walk both arrays with one counter. The caveat here is that if one has an extra element, you will get missing results or errors.

Save keys of json arrays and use the next in each loop.
$json_keys = array_keys($json);
$i_key = 0;
foreach($html->find('table.fixtures') as $matches)
{
foreach ($matches->find('tr[class=a1],tr[class=a2]') as $matchesTR) {
$kickofftime=$matchesTR->find('td[class=a11],td[class=a21]',0)->plaintext;
$kodate = date('Y-m-d H:i:s', strtotime("$matchday $kickofftime +1 hour"));
$result=$matchesTR->find('td');
echo $kodate;
echo $result[6]->plaintext.
$value = json_decode($json[$json_keys[$i_key++]], true);
echo $value["country"] . ", " . $value["competition"] . " " . $value["club"] . "<br>";
$i++;
}
}
// clean up memory
$html->clear();
unset($html);
There are many other variants - use array_shift(), next()... I've written the first come in mind
