Since you're using the 'e' modifier, the "replacement" string needs to be
valid PHP code. So, it should start with a variable or a function. A
replacement such as:
'print("<a href="{$1} .. ")'
should work.
I didn't get a chance to answer you original question. I couldn't even get
that regular expression to match links in any tests that I did, but if it's
working for you, that's good. Couldn't you modify the expression to look for
0-60 characters that are not a space, followed by any amount of characters
that are not a space, and only actually match the first 0-60 to use in your
replacement string? Something like:
([^[:space:]]{0,60})[^[:space:]]*
Which will match up to 60 characters in $2 for example, and also allow form
more characters than that, but just not match them. This is assuming what
everyone else said is right and you fix the entire regex to match the preg
syntax...
