Hi All.
I'm really stuck so hoping someone on the list can help. I'm looking for single
regex that can find function calls with exactly 2 parameters. Basically, the
regex pattern would look something like this:
\(\s*(.+?)\s*,\s*([^,\)]+?)\s*\)
However, the second parameter could contain anything, including commas and
parentheses enclosed in quotes (or as part of a function that executes as the
second parameter). Here are some example function calls that the pattern should
find:
ereg('sdfs', ',)')
ereg('sdfs', addslashes(',)'))
This is a function call that should NOT match:
ereg('sdfs', addslashes(',)'), $regs)
The one variable that will always be true is that if there is a third parameter
it will always be preceded by a comma (and optional space) and match this
regex: \$[a-z_][a-z0-9_]* (a valid variable name in PHP).
I suspect the answer may contain some combination of recursion and conditional
patterns, but I just can't believe there isn't a simpler solution as in my
experience, complex solutions simply aren't!
Thanks in advance to anyone who can lend a hand.
Sincerely,
Ted Stresen-Reuter
