How to get useful error messages in PHP

Many times I will try to run a PHP script but will just get a blank screen. No error message, just a blank screen. The cause could be a simple syntax error (wrong parentheses, missing semicolon), or a failed function call, or something else entirely. It's hard to figure out what's wrong. I ended up commenting out the code, adding "echo" statements here and there, etc. to try to narrow down the scope of the problem. But there has to be a better way, right? Is there a way to make PHP generate a useful error message like Java does?

Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit

CSS Grid: Create new row when child content overflows column width

I have a two column layout based on CSS grid. When the content of the second column exceeds 1fr I want to create a new row. As it currently stands, the content simply overflows the column. One requirement of this layout is that the items in the right menu column are in one row. I achieve this with: .right-menu{...grid-auto-flow:columndense;...} If I remove the grid-auto-flow attribute, the overflow stops. However, the items are now stacked into multiple rows, which is not what I want. I also tried converting .ri
