Convert a string to an array and validate each value

Exactly what do you want to validate? But I would definitely use the

FILTER_SANITIZE_URL

Method. Also found https://laracasts.com/discuss/channels/general-discussion/url-validation

i want to validate if each individual url are valids. The data is a string and if found a , then store in an array the string before the , and the string after the , and once that is done i need to go for each this array and validate if it is an url or not.

@viktort1t0 Create a custom validation rule for that and use this logic there. It's url rule.

So for your value just use explode with comma , delimeter and check it in the foreach statement.

Sorry when you said "How can i validate each of this URLs after separated", I thought you were only looking for the validation part. Otherwise I would have mentioned explode.

But the link has a good @bobbybouwmann answer.

How are you storing the data, you may want to store in Json format, or a related table.
