I am relatively new to PHP and I have been learning about arrays. Recently, I came across the "array_filter()" function in PHP and I am a bit confused about how it works.
I understand that array_filter() is used to filter out elements of an array based on a callback function. But I would really appreciate it if someone could provide me with a clear example to help me fully grasp the concept.
If possible, could you also explain any additional parameters that can be used with this function? I want to make sure I am using it correctly.
Thank you so much for your help in advance!
