Why the Loop not properly Looping through the data? - php

Question

<?php
$id = array(
"UC4MubF2asPHQbXN44DVNeXg",
"UCXuDgoo_oiZf8UkIXs3Y_kw",
"UCMnDuOzzJrWzr5tfemDcqlQ",
"UC9FH1mkHLFQuPPEPu9CfR1A",
"UCfyEAw41i7PRetP2erYf9dg",
);
// Getting Emails from DB and Looping with Channel Title and Video Title
$conn = mysqli_connect("localhost","username","password","dbname");
$query = "SELECT * FROM prospects ORDER BY email";
$rows = mysqli_query($conn, $query);
while($row = mysqli_fetch_array($rows)) {
$to[] = $row['email'];
}
$size = sizeof($id);
//echo "<br>Number of channel Ids: ".$size."<br><br>";
// Looping each Url for Each Email to get Data
foreach($to as $t){
echo $t."<br>";
for ($i = 0; $i < $size; $i++) {
$url = "https://www.youtube.com/channel/$id[$i]";
// echo $url."<br>";
$channel = trim(explode('https://www.youtube.com/channel/', $url)[1]);
// echo $channel."<br>";
$rss = "https://www.youtube.com/feeds/videos.xml?channel_id=$channel";
// echo $rss."<br>";
$xml = simplexml_load_file($rss);
$title = $xml->title;
// echo $title."<br>";
$videoTitle = $xml->entry[0]->title;
// echo $videoTitle."<br>";
$id[$i] = $xml->id;
// echo $id[$i]."<br>";
// $idOnly = substr($id[$i] , strpos($id[$i] , "yt:channel:") + 11);
// echo $idOnly."<br>";
$pub[$i] = $xml->entry[0]->published;
// echo $pub[$i]."<br>";
$realDate_ = new DateTime($pub[$i]);
// var_dump($realDate_);
$realDate2_ = $realDate_->format("D, d M Y")."<br>";
//echo $realDate2_;
$today_ = new DateTime();
// $today2_ = $today_->format("D, d M Y")."<br>";
// echo $today2_;
// if ($today2_ == $realDate2_) {
// echo "true";
// This is the Result with Every Email
echo $content = "• <a href='https://bladingflix.com/render.php?email=$t&channel=$idOnly'>".$title." - ".$videoTitle."</a><br>";
// }
}
}
?>
For the First Email the Data Shows Properly but in for the others
Purpose = get collected links add the user email to each url repeat for each.

Answer 1

Please make below changes in your existing code
In the second for() loop you are replacing the $id array as below
$id[$i] = $xml->id;
Instead of replacing the $id[$i] value, create new variable as below
$xmlId = $xml->id;
$idOnly = substr($xmlId, strpos($xmlId , "yt:channel:") + 11);
And please uncomment the $idOnly variable.
It will work. And try to refactor this code.
