I don't like to answer my own question, but in case someone else is
looking... The following regex does what I need, more or less:
(?x)
ereg\(
# find the first parameter, which could be a string, a variable, or
embedded functions
(["'])?(?(1)(((?:\\?.)*?)(\1))|(\$)?(?(5)([a-z][a-z0-9_]*)|([a-z][a-
z0-9_]*\(.*\))?))
\s*,\s*
# find the second parameter, which could be a string, a variable, or
embedded functions
(["'])?(?(8)(((?:\\?.)*?)(\8))|(\$)?(?(12)([a-z][a-z0-9_]*)|([a-z][a-
z0-9_]*\(.*\))?))\s*
\)
will match the following strings:
ereg('sdfs', $variable);
ereg('"', $variable);
ereg('"\'', $variable);
ereg($variable, '"\'');
ereg(addslashes($variable), '"\'');
ereg('"\'', addslashes($variable));
ereg('sdfs', addslashes($variable));
ereg('"', addslashes($variable));
ereg('"\'', addslashes($variable));
I am now able to search and replace ereg() for preg_match() in PHP
thus preparing my scripts for PHP 6. Wheeee!
Note that the (?x) simply tells BBEdit to ignore white space in the
pattern, but that \s* is necessary.
PS: And it only took me about 4 hours to get this working! ;-) Why do
such things always end up being sooo time-consuming?!?!
