What potential issues can arise from not following PHP variable naming conventions?

Not following PHP variable naming conventions can lead to confusion and readability issues in the code, making it harder for other developers to understand the purpose of each variable. To solve this, it's important to adhere to the standard naming conventions such as using camelCase for variable names and starting with a lowercase letter.
