Re: [wdvltalk] Regular Expressions in PHP
Thanks Dan and Sheila Now that I see where you're coming from I should be able to adapt it to match a lot of the other things I want to change. No doubt I'll be back when I hit problems!

Just to 'splain that a little ...
$string = '47-73';
$pattern = '/([0-9]+)(-)([0-9]+)/';
$replacement = '$1dash$3';
$new_string = preg_replace($pattern, $replacement, $string);
There are three sets of parens in the pattern. They get numbered left to
right $1, $2, $3. In the replacement string $1 and $3 are left alone and
the $2 is replaced by 'dash'.
Another way to write the replacement string that maybe makes this
clearer is
$replacement = '${1}dash${3}'

Re: [wdvltalk] Regular Expressions in PHP
I am not that familiar with PHP, but try using [0-9][0-9]-[0-9][0-9] HTH, Riva Ross Clutterbuck wrote: Hi all After many years of head-scratching trying to get to grips with Regular Expressions, I've come to a point in a project where I must utilise their power but I'm hitting brick walls already. I've writing a typography parser to convert standard keyboard-inputted characters into their typographical counterparts (quotation marks into curly quotes, proper Em and En dashes, etc.). I think I can identify characters based on patterns but I can't properly replace them. For example, I want to change a standard keyboard dash (the one paired with the underscore) into an Em dash when it's sandwiched between two numbers. Let's say we have in our string 45-78 I can successfully identify that dash with the pattern [0-9]-[0-9] but the string returned will be 5-7 so when I go to replace with my Em dash, it replaces the whole found string, not just the dash, giving 4—8 when I want 45—78 Obviously there's something big time I'm missing, or is my pattern incorrect? I want to identify a dash that is preceded and succeeded by a number, and change the dash only. Any help out there?
