Q:

Parse soundcloud "/sets/" url with Regular Expressions in PHP

Hello everyone,
I hope you are doing well. I have a question regarding parsing SoundCloud "/sets/" URLs using regular expressions in PHP.

I am currently working on a project where I need to extract information from SoundCloud sets URLs. For those who are unfamiliar, a SoundCloud set is a collection of tracks curated by a user.

Let me provide some background information about my project. I am building a music discovery app where users can find and listen to various music sets from SoundCloud. In order to properly display and play the sets, I need to extract the necessary information such as the set ID or slug from the URL.

For example, I would like to extract the set ID or slug from a URL like this: "https://soundcloud.com/user/sets/set_name". The set ID or slug is usually a string of numbers or characters that identifies the specific set.

Now, I understand that using regular expressions in PHP would be a suitable solution for parsing the SoundCloud sets URLs. However, I am not very familiar with regular expressions, so I am seeking guidance on how to construct the appropriate regex pattern for this task.

If anyone has experience in parsing SoundCloud URLs or has worked with regular expressions in PHP, I would greatly appreciate your help. Specifically, I am looking for assistance in constructing the regular expression pattern that can extract the set ID or slug from the "/sets/" URL.

Thank you in advance for your assistance and expertise. I am excited to learn from the knowledgeable members of this forum!

Hey folks,

I had a similar predicament and luckily found a neat way to tackle it. Parsing SoundCloud "/sets/" URLs using regular expressions in PHP can be quite handy, and I'd love to share my personal approach here.

In my project, I needed to extract specific information from the SoundCloud set URLs, just like the original poster. However, instead of diving straight into regular expressions, I came across an alternate solution using PHP's built-in URL parsing functions.

Here's a snippet illustrating how you can achieve this using the `parse_url()` and `explode()` functions:

php
$url = "https://soundcloud.com/user/sets/set_name";
$setSegments = explode('/', parse_url($url, PHP_URL_PATH));

if (in_array("sets", $setSegments) && isset($setSegments[array_search("sets", $setSegments) + 1])) {
$setIdOrSlug = $setSegments[array_search("sets", $setSegments) + 1];
// Now you have the set ID or slug, ready to be utilized in your project.
} else {
// The URL doesn't match the expected format.
}


In this approach, we start by utilizing `parse_url()` to extract the path from the URL. Next, we split the path into segments using `explode()` based on the forward slash ("/") delimiter. By checking if the "sets" keyword exists in the segments and ensuring the next segment is not empty, we can determine whether the URL follows the expected format.

If the condition is met, we extract the set ID or slug from the segments by locating the position of "sets" and retrieving the following segment. The result is then stored in `$setIdOrSlug` for further usage in your application.

Remember to tailor this code to fit your specific requirements. Feel free to integrate error handling or modify the logic to accommodate your project's needs.

I hope you find this alternative approach helpful! If you have any questions or need further assistance, feel free to reach out. I'm here to assist you.

Hey there!

I've encountered a similar situation before where I had to parse SoundCloud "/sets/" URLs using regular expressions in PHP. I found a solution that worked well for me, so I thought I'd share it with you.

To extract the set ID or slug from a SoundCloud "/sets/" URL, you can create a regular expression pattern in PHP. Here's an example of how you can do it:

php
$url = "https://soundcloud.com/user/sets/set_name";
$regex = '/\/sets\/([a-zA-Z0-9-_]+)/';

preg_match($regex, $url, $matches);

if (!empty($matches[1])) {
$setIdOrSlug = $matches[1];
// Now you have the set ID or slug, and you can use it in your app
} else {
// The URL doesn't match the expected format
}


In the above code, the regular expression `\/sets\/([a-zA-Z0-9-_]+)` is used. Here, `\/sets\/` matches the "/sets/" part of the URL, and `([a-zA-Z0-9-_]+)` captures the set ID or slug. The `([a-zA-Z0-9-_]+)` part matches any combination of alphanumeric characters, hyphens, and underscores and stores it in the `$matches` array.

You can then check if `$matches[1]` is not empty to ensure a successful match. If it's not empty, you can assign it to the variable `$setIdOrSlug` and utilize it for your app's functionality.

Remember to modify the code to fit your specific needs, such as handling the case when the URL doesn't match the expected format or incorporating it into your project architecture.

I hope this helps! Let me know if you have any further questions or need additional assistance.
