Question

how to convert permalink

'watch.php?a=RANDOMTEXT1&e=RANDOMTEXT2'

to

'watch/a/RANDOMTEXT1/e/RANDOMTEXT2.html'

with php preg_replace if RANDOMTEXT1 and RANDOMTEXT2 is random text?

Answer 1

You could use e.g. this regex:

(watch)\.php\?(a)=([^&]+)&(e)=([^&]+)

And replace it with:

$1/$2/$3/$4/$5.html

But it really depends on your requirements. Is this the only example where you need to create a link like this? You could also simplify the regex and only use watch\.php\?a=([^&]+)&e=([^&]+) and replace it with watch/a/$1/e/$2.html. If you want the regex to also allow & character, but only if they are not followed by an equal sign =, you would need to use negative lookaheads.
