RE: [PHP] Formatting phone numbers?
Jay, Here is a little more of the larger function with comments (more comments than code, which is never a Bad Thing [tm]). I am only showing the handling for two basic types of telephone numbers with explanation for additional verification which we would typically use, since we have those resources available. Great.

RE: [PHP] Formatting phone numbers?
Good stuff. [stuff you may not need] This is a boiled down version of a longer function that counts string lengths to determine how many dashes might need to be added. Let's say you have the area code in the number, like 2108765432. Being a ten digit number with a recognizable area code we can then add a portion to the function to add the two needed dashes, making the number more readable.

From the article, Im getting lost with the reason/meaning/purpose of

If anyone can clarify it for me, and let me know if my example would

RE: [PHP] Re: rich text editing
The only problem in doing so, for me at least, is in editing text created by htmlarea. Nonsupported users who get a normal textarea pre-loaded with html generated by htmlarea could break tags, etc., on updates. I wrote a class I use to work around this by: determining which type of textarea they'll get (wysiwyg htmlarea or plain textarea), and if they're using a plain textarea and editing html, all html except for bold, italics and underline tags are replaced with markers. The plain textarea user then can add standard bb style tags, [b], [i], etc., then on submit the bb tags will be converted to html, and the original html will be added back in, properly nested, etc. If you'd like to use it, I'd be happy to email it. I'm sure it could use a few extra sets of eyes.

[PHP] question on preg_replace()
I'm having a problem figuring out how to prevent preg_replace() from
replacing substrings when one element of the pattern array matches a
portion of a string that would match a subsequent value in the pattern
array.
Say I have an two arrays:
find = Array
(
[0] = 'fred'
[1] = 'tom'
[2] = 'frederick'
)
replace = Array
(
[0] = 'person1'
[1] = 'person2'
[2] = 'person3'
)
and a string $string = 'fred knows tom who knows frederick'. So the
string contains an instance of each $find value, and I'd like to replace
each one with its corresponding $replace value.
The problem is that preg_replace() changes 'frederick' to 'person1erick'
before even getting to find[2] ('frederick'), which at this point won't
find anything to replace, and I'm left with 'person1 knows person2 who
knows person1erick' when what I want to end up with is 'person1 knows
person2 knows person3.'
Also, the actual values in the $find array are not names but strings
representing each unique combination of HTML tags in $string (such as
'br', 'b', 'bru', so that the u here would be left over
unmatched). It seems to me that my only option is to write a function to
sort $find in reverse order by length, so that the longer strings are
replaced first. Or am I missing something obvious?
Thanks in advance,
Andy

RE: [PHP] preg_match question: locating unmatched HTML tags
Ernest,
Thanks very much. This is pretty close to what I'm looking for. The only
problem is that it doesn't catch nested tags. For example, some btext
/usome/b text some text makes it through without error since, I
think, preg_match resumes matching at the /b after spotting and then
checking its first match, at b.

Hi,
I don't believe you can create a regular expression to look for
something
that's NOT there.
I'd take this approach (tested with drawbacks, see below):
function check_tags($text) {
$suspect_tags = b|i|u|strong|em|font|a|ol|ul|blockquote;
$re_find = '/\s*(' . $suspect_tags . ').*?(.*)/is';
while (preg_match($re_find,$text,$matches)) {
// a suspect tag was found, check if closed
$suspect = $matches[1];
$text = $matches[2];
$re_close = '/\s*\/\s*' . $suspect . '\s*?(.*)/is';
if (preg_match($re_close, $text, $matches)) {
// fine, found matching closer, continue loop
$text = $matches[1];
}
else {
// not closed - return to report it
return $suspect;
}
}
return null;
}
$text = EOT
This text contains font
size=+4 an
unclosed suspect /finttag.
EOT;
$tag = check_tags($text);
if ($tag) echo Unmatched: \$tag\\n;
else echo Perfect!\n;
The drawbacks: This approach is softly targeted at unintended typos,
such
as in the example text. It won't catch deliberate attacks, such as
Blindtext font color=redfont size=+22Hehe I've got you/font
because it is missing the second font opener. To catch these attacks
you'd
need to build a source tree of the text in question.
HTH,

Your response helped me find the answer. On the recursive call to
breadcrumbs(), the function wasn't actually returning anything to

I think it will work if you return true, and just modify the global
variable (not try to output it).
Then output it (or capture it to begin with ($total_count =
OneHundred();) after the function is called.
You could also pass the variable, rather than making it global
(OneHundred(0) initially, and OneHundred($count) from within the
function).
For instance:
?php
function OneHundred(){
global $count;
if($count 100){
$count++;
OneHundred();
}
return true;
}
OneHundred();
echo $count;
?
Hope that helps,

RE: [PHP] Trouble with understanding arrays
It looks like your problem is simply in the debug line, where you echo
print_r(array_values($TickersCurrent));
You shouldn't call array_values() before print_r(), since array_values
generates an indexed array of only the values (quotes), not the keys
(tickers), of the supplied array, essentially taking your quotes from
your ticker=quote pairs and replacing the tickers with an index. Just
do print_r($TickersCurrent) and you'll get the desired result.
Hope that helps,
Andy

Subject: [PHP] Trouble with understanding arrays
I am having problems with arrays. I guess I just don't understand them
all
that well.
I have an simple array of stock tickers. Then for each ticker I go to
Yahoo
to get their current price and try to push the Name of the ticker and
it's
value into an associative array(I think). Then I want to sort the array
so
the the values are in order from highest to lowest, so I can see the
highest
amount as the first position and the lowest as the last position.
Here is my problem; for debuggin purposes I do a
print_r(array_values());
and I get the following for output.
Array
(
[0] = 7.28
[1] = 5.20
[2] = 1.969
[3] = 59.63
[4] = 4.43
)
I am not sure why I am getting this. I guess I expected the numerical
positions to be the keys something like:
Array
(
[ikn] = 7.28
[xrx] = 5.20
[danky] = 1.969
[ibm] = 59.63
[rhat] = 4.43
)
Since I am not getting the results I expected I am not sure if the rest
is
working correctly because I do not know how to access the first position
in
the array, or the last. When I get this working, I will be adding 200
tickers and I would like to get the first 5 and the last 5, expecting
them
to be the highest 5 and the lowest 5 respectively. I hope someone will
take
the time to halp me.
Thank you in advance.
Here is the code I am working on:
$Tickers = array(ikn, xrx, danky, ibm, rhat);
$TickersCurrent = array();
foreach($Tickers as $Ticker) {
$LookupUrl =
http://finance.yahoo.com/d/quotes.csv?s=$Tickerf=l1e=.txt;;
$Current = implode('', file($LookupUrl));
$Current = rtrim($Current);
$TickersCurrent[$Ticker]=$Current;
}
// Done for debuggin only
print pre\n;
print_r(array_values($TickersCurrent));
print /pre\n;
asort ($TickersCurrent);
reset ($TickersCurrent);
echo CTC Indice = . array_sum($TickersCurrent) . br\n;
echo The highest Stock is $TickersCurrent[0];
