I hope you're all doing well. I'm new to PHP and I've come across something that has intrigued me. I've noticed that PHP variables always start with a $ sign symbol. I was wondering, why is this the case? What is the reason behind using the $ sign symbol for variables in PHP?
I'm really curious about the historical or logical background behind this syntax. Is there any particular reason why PHP chose to use the $ sign symbol to indicate variables? I haven't seen this in other programming languages I've previously worked with, so it caught my attention.
I would love to hear your insights on this matter. Is there a specific reason for this unique syntax in PHP, or is it just a convention that has been widely accepted? Any thoughts or information on this would be greatly appreciated.
Looking forward to learning from your expertise.
Thank you in advance!
