Fixing my search form in HTML with embedded PHP? - php

Question

So I have a PHP page which has an ordered list that I am scanning from a text file which looks like this:
Here is the code for it as well:
<?php
foreach (file("Files/music.txt") as $music){
list($title,$artist,$link) = explode(",",$music);
?>
<li>
<a href=<?php echo $link ?>><?php echo $title ?> by <?php echo $artist ?></a>
</li>
<?php } ?>
</ol>
</div>
What I need is to be able to search the title for the song and to only display that with the form I have in the picture. I have to use only the $_GET and a function to make it work. Here is the code for the form that I am messing around with:
<form action="blog.php">
Search for Title:
<input type="text" name="title">
<input type="submit" value="Search">
<br>
Sort by song title
Unsorted
<?php
function printSongs($searchTitles=""){
if(isset($searchTitles)){
global $title;
if ($searchTitle == $title){
echo $title;
}
}
}
$userInput = $_GET["title"];
printSongs($userInput);
?>
</form>
Any advice would help alot. Thank you!

Answer 1

try using The SplFileObject class in PHP try this code
<?php
function printSongs($searchTitles=""){
$file = new SplFileObject("Files/music.txt");
$music="";
while (!$file->eof()) {
$music= $file->fgets();
$data= explode(",",$music);
if (in_array($searchTitles, $data))
{
//match is found
echo data[1];
}
}
}
$userInput = $_GET["title"];
printSongs($userInput);
?>
