I am creating some EPG for the website. I do not have experience. Unfortunately, I'm finding it difficult. How can I get the icons, what is wrong in this code?`
Final code working:
<?php
$url = 'XML URL LINK';
$xml=simplexml_load_file("$url");
$progs = $xml->xpath('//programme');
foreach ($progs as $prog) {
$title = $prog->xpath('./title/text()')[0];
$link = (count($prog->xpath('./icon/#src'))>0) ? ($prog->xpath('./icon/#src'))[0] : ("No icon");
echo "Logo: <img src='{$link}'> <br/>" ;
echo "Title : ".$title. "<br>";
echo "<br>";
}
?>
If I understand you correctly, something like this should get you close to what I think you are trying to do. Note that not all programs have associated logos.
$progs = $xml->xpath('//programme');
foreach ($progs as $prog) {
$title = $prog->xpath('./title/text()')[0];
$link = (count($prog->xpath('./icon/#src'))>0) ? ($prog->xpath('./icon/#src'))[0] : ("No icon");
echo($title .": ". $link);
echo "\r\n";
}
EDIT:
I'm still not entirely sure I understand what you want, but it sounds like you need to wrap the whole thing in html and output to a browser. Something like:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<?php
$url = 'https://raw.githubusercontent.com/HelmerLuzo/TDTChannels_EPG/master/TDTChannels_EPG.xml';
$xml=simplexml_load_file("$url");
$progs = $xml->xpath('//programme');
foreach ($progs as $prog) {
$title = $prog->xpath('./title/text()')[0];
$link = (count($prog->xpath('./icon/#src'))>0) ? ($prog->xpath('./icon/#src'))[0] : ("No icon");
echo "Logo: <img src='{$link}'> <br/>" ;
echo "Title : ".$title. "<br>";
echo "<br>";
}
?>
</body>
</html>
This was a fun one. This uses a known hack to convert the xml into an array using json_decode and json_encode, this makes it easier to work with in my opinion. It also makes extensive use of the DateTime object.
$url = 'https://raw.githubusercontent.com/HelmerLuzo/TDTChannels_EPG/master/TDTChannels_EPG.xml';
$xml = simplexml_load_file($url);
$xml = json_decode(json_encode($xml), true); // Hack so we don't have to cast values in the future
// https://www.php.net/manual/en/timezones.php
$originalTimezone = 'Europe/Madrid';
$changeTimezone = 'Australia/Sydney'; // If empty, will not change timezone
//$outputFormat = 'Y-m-d H:i:s O';
$outputFormat = 'G:i';
$channels = [];
foreach ($xml['channel'] as $channel) {
$id = $channel['#attributes']['id'];
$channels[$id]['Display Name'] = $channel['display-name'];
$channels[$id]['Now Showing'] = [];
}
$now = new DateTime('now', new DateTimeZone($originalTimezone));
$programmes = [];
foreach ($xml['programme'] as $programme) {
$id = $programme['#attributes']['channel'];
$start = $programme['#attributes']['start'];
$start = DateTime::createFromFormat('YmdHis O', $start);
if (!empty($changeTimezone))
$start = $start->setTimezone(new DateTimeZone($changeTimezone));
$stop = $programme['#attributes']['stop'];
$stop = DateTime::createFromFormat('YmdHis O', $stop);
if (!empty($changeTimezone))
$stop = $stop->setTimezone(new DateTimeZone($changeTimezone));
if ($start < $now && $now < $stop) {
$nowShowing = [
'Title' => $programme['title'],
'Subtitle' => '',
'Description' => '',
'Date' => '',
'Start' => '',
'Stop' => '',
'Icon' => '',
];
if (isset($programme['sub-title']))
$nowShowing['Subtitle'] = $programme['sub-title'];
if (isset($programme['desc']))
$nowShowing['Description'] = $programme['desc'];
if (isset($programme['date']))
$nowShowing['Date'] = $programme['date'];
if (isset($programme['date']))
$nowShowing['Icon'] = $programme['icon']['#attributes']['src'];
$nowShowing['Start'] = $start->format($outputFormat);
$nowShowing['Stop'] = $stop->format($outputFormat);
$channels[$id]['Now Showing'] = $nowShowing;
}
}
foreach ($channels as $id => $details) {
echo $details['Now Showing']['Start'] . ' - ' . $details['Now Showing']['Stop'] . '<br>' .
'Channel:' . $details['Display Name'] . '<br>' .
'Title: ' . $details['Now Showing']['Title'] . '<br>' .

I don't know what are the errors of this code because it's suddenly not accurate the showing value to the user like this:
$holidays = array();
$query_holiday = "SELECT * FROM holiday_tbl";
$result = mysqli_query($dbcon, $query_holiday);
while($row_holiday = mysqli_fetch_assoc($result))
{
array_push($row_holiday, $holidays);
}
if(strtotime(date("Y-m-d")) > strtotime($row['due_date']))
{
$currentDate = date("Y-m-d");
$days = (strtotime($currentDate) - strtotime($row['due_date'])) / 86400;
$daysTemp = $days;
for($i=1;$i<$days;$i++)
{
$currentDay = date("D", strtotime("+ ".$i." days"));
$date_loop = date("Y-m-d", strtotime("+ ".$i." days"));
if($currentDay == "Sun" || $currentDay == "Sat")
{
$daysTemp--;
}
else if(in_array($date_loop, $holidays))
{
$daysTemp--;
}
}
echo $daysTemp;
}
The current implementation is rather convoluted. In these cases I find it's always better to start over and try to simplify the logic as much as possible. Here is my take on your problem:
function calculate_days_late($due_date = '', $holidays = array(), $current_date = 'today') {
$days_late = 0;
// Get the timestamps for due date and current date
$current_date_ts = strtotime($current_date);
$due_date_ts = strtotime($due_date);
// If current date is not after due date then not late
if ($current_date_ts <= $due_date_ts) {
return $days_late;
}
$loop_date_ts = $current_date_ts;
while ($loop_date_ts > $due_date_ts) {
// If the looping date is not a weekend or holiday then count it
if ( ! in_array(date('D', $loop_date_ts), array('Sat','Sun'))
&& ! in_array(date('Y-m-d', $loop_date_ts), $holidays)) {
$days_late++;
}
$loop_date_ts = strtotime('-1 day', $loop_date_ts);
}
return $days_late;
}
// Test
echo '2017-09-05 = ' . calculate_days_late('2017-09-05', array(), '2017-09-05') . "\n";
echo '2017-09-06 = ' . calculate_days_late('2017-09-05', array(), '2017-09-06') . "\n";
echo '2017-09-07 = ' . calculate_days_late('2017-09-05', array(), '2017-09-07') . "\n";
echo '2017-09-08 = ' . calculate_days_late('2017-09-05', array(), '2017-09-08') . "\n";
echo '2017-09-09 = ' . calculate_days_late('2017-09-05', array(), '2017-09-09') . "\n";
echo '2017-09-10 = ' . calculate_days_late('2017-09-05', array(), '2017-09-10') . "\n";
echo '2017-09-11 = ' . calculate_days_late('2017-09-05', array(), '2017-09-11') . "\n";
echo '2017-09-12 = ' . calculate_days_late('2017-09-05', array(), '2017-09-12') . "\n";
echo '2017-09-13 = ' . calculate_days_late('2017-09-05', array(), '2017-09-13') . "\n";
Working example: https://eval.in/856018
when i set some cron jobs for loading a php file cron doesn't work and it seams some php function have problem with cron job.
i know my cron command is true because i tested my cron job working true with simple php code that put date to a text file so my cron command is true i tested all ways of command like : wget, crul , cd, php , /user/local/bin/php and another but i don't know why my php code doesn't work and too i test that codes working very well when i loading php files with my browser.

I want to print both
<?php
//in file A
$_SESSION['cart']['prices'] = array('1000');
$_SESSION['cart']['services'] = array('game');
//In File B
$_SESSION['cart']['prices'] = array('2000');
$_SESSION['cart']['services'] = array('game2');
//in file C
foreach ($_SESSION['cart']['services'] as $key => $service) {
echo $service . ' = ' . $_SESSION['cart']['prices'][$key] . '<br />';
}
?>
Better use this :
$_SESSION['cart']['prices'][] = array('1000');
$_SESSION['cart']['services'][] = array('game');
//In File B
$_SESSION['cart']['prices'][] = array('2000');
$_SESSION['cart']['services'][] = array('game2');
According to the current data foreach loop will execute two times. It will print Array as $service is array array('1000') and array('2000') same as for $_SESSION['cart']['prices'][$key]
foreach ($_SESSION['cart']['services'] as $key => $service) {
echo $service . ' = ' . $_SESSION['cart']['prices'][$key] . '<br />';
}
Try this :
$array1 = array('1000','2000');
$array2 = array('game1','game2');
foreach($array1 as $index=>$key)
{
$_SESSION['cart']['prices'][] = $key;
$_SESSION['cart']['services'][] = $array2[$index];
}
foreach ($_SESSION['cart']['services'] as $key => $service) {
echo $service . ' = ' . $_SESSION['cart']['prices'][$key] . '<br />';
}
I'm using var_export to dump output to logs when errors occur. However since the result is in pure text, I don't get a chance to push it through some sort of library like krumo so I can interactively explores the output.
What methods do people have to deal with making var_export text more readable?
Here is my function, it works well for multidimensional arrays:
function VE($varname, $varval, $short_syntax=true, $tag = ' ', $comma='', $end_line="\r\n") {
$res = '';
if($short_syntax){
$begin_array = '[';
$end_array = ']';
} else {
$begin_array = 'array(';
$end_array = ')';
}
$arr = explode('/',$varname);
$dim =count($arr)-1;
$lastKey = end($arr);
if (! is_array($varval)){
if( is_string($varval)) $varval = "'$varval'";
$res .= str_repeat($tag,$dim) . $lastKey . ' => ' . $varval . $comma . $end_line;
}else{
$res .= str_repeat($tag,$dim) . $lastKey . ' => ' . $begin_array . $end_line;
$count_varval = 0;
$dim_varval = count($varval);
foreach ($varval as $key => $val){
$count_varval++;
if($count_varval<$dim_varval) $commma=','; else $commma='';
if( is_string($key)) $key = "'$key'";
$res .= VE ($varname . "/" . $key , $val, $short_syntax, $tag, $commma);
}
$res .= str_repeat($tag,$dim) . $end_array . $comma . $end_line;
}
return $res;
}
$bigarray = array(); // your array
$bb = VE ('$bigarray', $bigarray);
echo "<pre>$bb</pre>";
I hope it helps ;)
Would someone of you know why I'm not able to use a (long)piece of code within a foreach loop?
The code in the foreach loop is only executed once.
This code at topictweets.php works fine on its own but I want to repeat it for each forum.
The foreach loop works fine without the include. I also tried to have the code from topic tweets.php plainly in the foreach loop, this didn't work either of course.
The code it includes is used to get topics of a forum from the database and find related tweets, and save those in the database.
Is there some other way to do this?
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
include 'topictweets.php';
/////////
////////
}
online version: http://oudhollandsedrop.nl/webendata/FeedForum/fetchtweets.php
bunch of code in topic tweets.php

"Pasting" a bunch of code inside a loop isn't a great practice. In fact, what you're looking for is a function or the use of a defined class. So, if you can, define a function in your topictweets.php that will contain your code and use it in your loop:
include 'topictweets.php';
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
processYourForums($fID);
/////////
////////
}
try include_once()
however, why not have a loop within topictweets.php?
you can do the query, etc.. in this page, but then loop through it in the include
This should work fine:
include 'topictweets.php';
foreach ($forumlist as $x => $fID) {
echo 'id:'.$fID.'<br>';
}
You only need to include once.
