PHP String Replace

Report · Aug 26, 2006

I am looking to add my date to the beginning of my articles. Previously, I
was using the string replace function to look for the begininng of my
paragraph and then place the date in front of that. Bad Jon! I forgot that
any article with multiple paragraphs would then have multiple dates.

$artContent = str_replace('', ' '.$artDateEdited.' - ',
$artContent);

So, what I am looking for is how do I do a string replaceon just the first
paragraph?

http://www.php.net/manual/en/function.preg-replace.php

In particular, the optional 4th parameter to preg_replace() is a limit;
you can set this to 1.

LOL, just now getting back to this.

I've got myself in a little bit of a bind, b/c I didn't foresee my data
having more than one paragraph.

This is what I'm thinking of doing. If there's a better way, can somebody
pipe in?

Take data from database.
Search for tags, and capture all text within the first instances
Limit text to X number of chars
Replace tags, and my ...Full Story links

Looking now through all of the string functions and preg_replace right now.

Basically, I"m having some problems finding a function that will replace
$var on the Xth instance.

Will post tomorrow with my results.

Are you sure there are tags in the data? The only way that could get
there would be if someone explicitly put them there.

No, but I should have an I am. I am using the TinyMCE javascript component
to add WYSWIG functionality. In addition to this, my input forms should do
a search and replace to ensure all paragraphs have the request tags.

as long as I find the function. I'm able to find counting functions within
the preg_replace function, but it looks like it doesn't *analyze* the count.
I need it to take away the first paragraph tag and the last end paragraph
tag - not all of them.

Just digging through that [explicative] php.net site and trying to decipher.
I bet those guys communicate worse than I do! ;o) (just joking if you guys
are reading, it's wonderful)

i'll post back when i find the correct way to implement it. :D

does using a rtrim and ltrim sound like it's barking upt he wrong alley?

I've been looking for counting things, but if I just start from the right
and replace the tag, and then start from the left and replace the 
tag (backwards) then I should be able to do it with two simple statements
instead of a long complicated one, no?

Or am I overlooking a funciton?

Again, kinda rhetorical as I'm assuming there is not a function to do this
and am moving ahead with rtrim etc.

Man, oh man. If Jon missed any more forests for the trees....

This is what I needed up doing, and it is much easier, prettier, etc. etc.
Looks (in my testing) to work perfectly.

if ($row_rsFrontPage['newsShortDesc'] != ''){//if short description exists
$fpCont = $row_rsFrontPage['newsShortDesc'];
if(strlen($fpCont) > 350){//if descrp is greater than 350
$fpCont = truncate_string($fpCont, 350);}
$fpCont = ltrim($fpCont, "");//remove any preceding if exists
$fpCont = rtrim($fpCont, "");//same for *last* tag, not *all*

$fpCont = ''.$fpDateEdited.$fpCont.' <a
href="news.php?cid='.$fpID.'">Full Story</a>'; //complie content and get
on your way.

Gads, but that was so simple. What a maroon! ;o)

Thanks guys for all your help, and if you saw this before I did, thanks for
not saying anything. :O) That was one that while I feel silly for missing
the obvious, will hopefully help my process in the future.

Thanks mate. It's just the way it looks. they're actually two single quotes
' '
not one double.

It doesn't make a difference what kind of quotes you use, does it? I
typically use ' to designate when I'm starting a string, but other than
that, when looking for values, I think I tend to migrate between the two b/c
I didn't think it made a difference.

Does it?

Actually, it does. In strings delimited with double quotes (0x22), PHP

understands ... escape sequences for special characters [and]
variable names will be expanded.

http://www.php.net/manual/en/language.types.string.php

(Sorry. I caught your message about wading through php.net, but it's the
best technical explanation around... <grin>)

This has two practical consequences:
- it allows you to do more with the string
- it puts more load on the server

So to give a long answer to a short question, yes, it's best to use
single quotes in most circumstances.

Ahh my bad sorry.

I would use double quotes for something like this, not sure about the single
quote, if I did it that way but in my own code I would actually write the if
statement like so:-

$field = trim($row_rsFrontPage['newsShortDesc']);
if (strlen($field) > 0) { //if short description exists
$fpCont = $row_rsFrontPage['newsShortDesc'];
}

but that's just my way of doing things

hehee, no worries. PHP.net has great info. It's just a bear [for me] to
search through and read sometimes. Probably b/c by the time you're going
there, you're all bug-eyed and crossy anyway.

This makes sense to me now. I had experienced some problems with this (the
other guy codes for new lines) but just wrote it off to ... well...I guess
exactly what it was, syntax. I had not done the troubleshooting on it,
though. Thanks a ton!

Cool, I'll save it for when needed. I'm glad you mentioned the server load,
as it's easy to see in hindsight, but I would most likely have adapted
widespread use of double's just b/c I'm lazy and I can see how that would
cut down on some coding (at least punctuation).

Thanks Joe, great info as usual!
