Can I learn PHP MySQL with no mathematical background? If so, how long does the learning process take before you can actually get hired for a junior position?

I’m not sure what a mathematical background has to do with learning structured programming languages. Languages like PHP and MySQL only require a competent understanding of two things: Logic - understanding the relationship of cause and effect, as in, “if condition A is true, then perform operation M.” Syntax - understanding the mnemonic language used to describe the flow of logic in the program. My belief is that anyone who can learn one programming language can (for the most part) learn any other, because the core logical understanding is critical, and the syntactical elements are what reference materials are for. You don’t need to commit syntax of a specific programming language to memory, you just need to know generally what you are trying to do, and then you can look up the specific syntax for the language you’re using.In fact, most code is initially designed using “pseudo-code,” which is just a way of describing the logic patterns without getting bogged down in the details of the syntax. Theoretically, with pseudo-code handy, you should be able to write a program in almost any programming language with only a little effort to understand the conventions of the programming language (are variables declared using a symbol, or not; do you put some kind of delimiter at the end of a line, or not; how are parentheses, brackets and braces used; etc.?).If you understand the concept of an “if…then…else” logic decision, you ought to be able to spend less than 5 minutes looking in a book or online to find the specific syntax to successfully implement that as code in a particular language, even if it’s a language you’ve ever programmed in before. But if you don’t understand the logic, knowing the syntax is pretty much useless.

No need of any mathematical background. Learning any programming language totally depends on you, how much time you will give to it, how much good you are at learning things. If you are good at learning new things you will take at least a month to become good on it.

Yes. I studied no maths in high school and no maths in college an am currently a professional developer. However, you will need to know logic. Philosophy was a non-math set of courses that prepared me for being a developer. The most intense math you could possibly need as a Jr. Dev doing php and sql is algebra.
