string question

reidme

Hi 😃
I have a string of $data, I have $ed_start_pos and $ed_end_pos in data, I want to insert a $string at ed_start, and another $string at ed_end. What function should I use?
I have looked a str section of manual and can find nothing
Thanks 😃

$new_string=$string.$old_string.$string

it is the period operator.

Thankyou for your input 😃
I think I need to explain myself better.
I have a db field called content and in there is stored all the content of an article.
Anywhere within the article there could be some user tags: [ed] and [/ed] for instance.
The text in between the tags:
[ed] This is an editors comment [/ed]
needs to remain and initially be parsed for a $string (search query string) and a <bgcolour> highlighting take place.
Then I need to replace the '[ed]' with '<p class="class">Editors Note:<br>' and the '[/ed]' with '</p>'.

It works fine until someone searches for 'ed', then the $string search tries to highlight the 'ed' in 'Editors Note:' and messes up the class code. So what I am trying to do is remove the '[ed]' and '[/ed]' tags while storing their their positions in variables, and then after the search parsing is done, insert the class wrapping tags into the Article.
Hope that makes more sense.
Thank you again 😃

you may want to make those changes before the data is inserted in the table...it will make all the seaches that much easier

what replacing various facets of the code with other tidbits...

like replacing [ed] and [/ed] with [] and [/]

which is simply done with [man]preg_replace[/man] or [man]str_replace[/man] then when presenting the data you make those changes to have those tags back again using preg_replace or str_replace....

just work out a little code system whereby you can account for all facets of the tags that you wish to replace...

I did exactly that while I was waiting for a reply:

                $ed_open = "[ed]";
	if (strstr($data, $ed_open)) {
	$ed_close = "[/ed]";
	$data = str_replace($ed_open, '{|}', $data);
	$data = str_replace($ed_close, '{||}', $data);
	} 
	$foot_open = "[foot]";
	if (strstr($data, $foot_open)) {
	$foot_close = "[/foot]";
	$data = str_replace($foot_open, '{|||}', $data);
	$data = str_replace($foot_close, '{||||}', $data);
	}

Then after the search $string has been parsed:

if (isset($ed_close)) {
	$data = str_replace('{|}', '<p class="editor"><u><b>Editors Note:</b></u>', $data);
	$data = str_replace('{||}', '</p>', $data);
	}
	if (isset($foot_close)) {
	$data = str_replace('{|||}', '<p class="footnote"><u><b>Footnote:</b></u>', $data);
	$data = str_replace('{||||}', '</p>', $data);
	}

It works well, but I am suprised there isnt a function that inserts a string into a string at a certain position.
While we are in this thread, my next mission is to parse the [url="address.com]link text[/url] tags. I need to extract the $address and $link_text vars so I can use them in the link replacement code. The first thing that conerns me is that there could be more than one set of [url] tags in an article, I have been advised to look at how a fprum does this, so will do that for now, but if you have any pointers I would appreciate your expertise.
Thankyou again 😃
