Re: [PHP] Parsing brackets in text
Actually, preg_replace() can solve Dotan Cohen's problem. There was just a
minor mistake in the code.
Please try this:
$title";
return $returnString;
}
$articleText="This is a very [long] and [stupid] string.";
$articleText=preg_replace('/(\[[a-z]+\])/e', "makeLink('$1')",
$articleText);
print $articleText;
?>

It's done this way in all the examples on
http://cz.php.net/manual/en/function.preg-replace-callback.php
What documentation did you read?
In the first example on that page, it looks to me like it should just
return the text "next_year", and not call that function. Obviously, it
is my misunderstanding of the way that the funciton works, and not in
the function itself. I do learn php from TFM and this list, not from a
course. Just like in any learning environment, I could misinterpret
what is taught to me and need to ask a question, or not even know that
I misinterpreted and not know that I need to ask a question. This is a
case of the latter, clearly, because I have never needed to do
anything other than a simple str_replace until now.

No need to google:
http://cz.php.net/manual/en/reference.pcre.pattern.syntax.php

That I have read at least three or four times. I still don't capture
all of it, but I try. You are correct, I should have referenced that
right away. It won't hurt for me to read it again, too. Thank you.

The callback takes whatever the regular expressions returns (alpha
characters between [ and ]) and runs it through function "makeLink".
Not sure how that will go with multiple []'s etc in the same string but
it should get you started.
I didn't know that I had to call the function like that- I don't
remember ever seeing it called that way. Also, I must google the
meaning of the (~+) in the regex.
Thank you very much, Chris. I very much appreciate the assistance.
Know that I am learning, not just asking for hand-holding!

Ah, completely missed that part. You can't pass "$1" through like that.
You have to do some funky quoting to do what you want in one go.
http://php.net/preg_replace
Check "Example 4. Using the 'e' modifier"
or use a callback:
http://www.php.net/manual/en/function.preg-replace-callback.php
I had looked at both of those already- with neither luck nor
understanding. I can fuddle my way through a simple regex, but that
monster has me bewildered. I'm pretty sure that preg_replace is all I
need, but I can't figure out the correct syntax for referencing a
chunk of the data.
I'm of course not asking anybody to write the regex for me, rather to
show me how it must be so that I'll know how to construct them. I saw
another, similar example on ilovejackdaniels.com where the author had
parsed Google query strings, but that example was even more confounded
than the one in TFphpM.
" . $matches[1] . "";
return $returnString;
}
$articleText="This is a very [long] string.";
$articleText=preg_replace_callback('/\[([a-z]+)\]/i' , "makeLink",
$articleText);
print $articleText . "\n";
?>
The callback takes whatever the regular expressions returns (alpha
characters between [ and ]) and runs it through function "makeLink".
Not sure how that will go with multiple []'s etc in the same string but
it should get you started.

Don't know if this is your problem but you need to escape the trailing ]
as well:
preg_replace('/\[[a-z]\]/i', .
Thanks, but that wasn't quite it, either. This code:
$title";
return $returnString;
}
$articleText="This is a very [long] string.";
$articleText=preg_replace('/\[[a-z]\]/i' , makeLink($1), $articleText);
print $articleText;
?>
produces this error:
Parse error: syntax error, unexpected T_LNUMBER, expecting T_VARIABLE
or '$' in /home/user/public_html/testpage.php on line 9
I'm sorry that I didn't include the error message in my original
email. Also, I got the same error with and without the last closing
bracket escaped.
