I set a breakpoint on a line in this thrigger-file $t, but the debugger does not stop there. |
I'm not sure that I got you right. Suppose for a particular case $t has 'tableA.inc' value and you have 'tableA.inc' file in your system. You can set a breakpoint in this file and it will trigger the debugger. If it does not what happen in your case, you may want to check:
a) that the file where you set breakpoint is the file that gets actually included when you check it by stepping in the debugger
b) that the line where you set the breakpoint gets blue dot when you step with debugger in the file
c) that you have no php opcode caches like eaccelerator and its successors. They cache files when you run them for the first time and if you do so without debugger, they will be cached without debugging opcodes so they can be debugged.
