Don't use grep. Try this (untested):

preg_replace('/__([a-z0-9]+)__/i', '$1', $string);

You may want to expand the character class.

Don't use regex if not necessary.

$fixedstring = str_replace ('__abc__',' abc',$yourstring ,[$count]);
$count, if supplied, tallies the number of replacements made.

preg_replace('/__(\w+?)__/', '$1', $string)

or

preg_replace('/\b__(\w+?)__\b/', '$1', $string)

the latter replaces only whole words, i.e. "xxx __blah__ xxx" but not
"zzz__blah___zz z".

Assuming this is for a simplified text markup system, don't reinvent the
wheel.

Take a look at:

- Markdown
- Textile
- BB Code
- Wiki markup

There are freely available PHP implementations of each of these. Some are
in PEAR -- you'll need to use Google for the others.
