How do I use strcspn() to extract values in an SQL argument?

Hi,

I'm trying to extract MySQL insert values into a PHP array. Each field value is delimited by a comma, though surrounding each comma can be a single quote, a closed bracket, an uppercase letter denoting the start of a MySQL function or an integer. Finding the start and end of each value is made more complicated by concatenated values. I don't want to use regex as I need greater efficiency for this particular code and was looking into strcspn - can anyone show me some code demonstrating strcspn splitting an SQL expression?

Thanks

Maybe instead of reinventing the wheel, you could use already made class to parse insert queries.  Here's one example based on tokens, not regex, so it should be fast enough:

It includes insert queries parser.

I resolved the problem using strpos and looping.
