I read the links you sent, plus some others. It took me awhile, but
I get it now. If the return character that was entered into that
field is not the same as what PHP_EOL is looking for, it won't work.
$parts = preg_split('|[\n\r]+|', $item['unitprice']);
preg_split works perfectly! Very similar to Perl's split function.
Here's what I have now:
$parts = preg_split('|\s+|', $item['unitprice']);
$price = '$'.number_format((count($parts) 1) ?
$parts[(count($parts)-1)] : $parts[0],2);
Clean and concise. Thanks a million, Jim! I really appreciate your
helpful responses.
Thanks again,
Frank

Re: [PHP] RIGHT Function?
I think I've solved a problem that I had posted back in September. Here's a recap: == I need to grab a dollar amount from a text field in a MySQL db that can contain more information than just the price. Here are 4 examples of what could be in that field: 48,(min) 2.66 24,(min) 10.50 4,(min) 104.82 98.56 If there is more info in that field than just the price (as in the first 3 examples), the price is always on the 2nd line. == The following code works with the tests I've given it so far, but I just want to double check before I go live with it: ... if ($position = strpos($item['unitprice'], ')') ) $price = $ . number_format(substr($item['unitprice'], $position + 1),2); else $price = $ . number_format($item['unitprice'],2); ... Legend: $item['unitprice'] is coming from a MySQL statement I'm grabbing the position of the right parentheses and adding 1 to it. Then the substr grabs everything from that point to the end of the string, correct? If there isn't a ) in the field, then the else statement should be performed. Can anyone see any errors in my code? Would there be a better way to write this? Thanks again, Frank -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] RIGHT Function?
Hi Jim, $parts = explode(PHP_EOL, $item['unitprice']); $price = '$'.(( count($parts) 1 ) ? $parts[0] : $parts[(count($parts)-1)]); Thanks for the code! After reading up on PHP_EOL and explode, I now understand what you've done. However, can you tell me why you like this better? Is it because it is cleaner without the if/else statements, or is there more to it than that?

Re: [PHP] RIGHT Function?
Jim,
$parts = explode(PHP_EOL, $item['unitprice']);
$price = '$'.(( count($parts) 1 ) ? $parts[0] :
$parts[(count($parts)-1)]);
For some reason, I couldn't get explode to work with PHP_EOL.
$parts[0] would return the entire field, so apparently it wasn't
exploding. So I tried exploding on the ')' instead, which worked,
but the return character that's after the ')' was included in the
output, i.e.:
$
6.56
so I added 'trim' which took care of that. I also had to use
'number_format' again, since there are exact dollar amounts like 413.
Here's what ended up working for me:
$parts = explode(')', $item['unitprice']);
$price = '$'.number_format(trim((( count($parts) 1 ) ?
$parts[(count($parts)-1)] : $parts[0])),2);
Any idea why PHP_EOL didn't work? If I could get it to work, I could
remove the trim function and 2 of those parentheses, which would look
a lot nicer.
Thanks again,
Frank

Basically, you are using an if-then-else statement.
Read here:
http://us2.php.net/manual/en/control-structures.alternative-syntax.php
As for the PHP_EOL:
Read here: http://us2.php.net/manual/en/reserved.constants.php
and search for PHP_EOL
You basic problem with the PHP_EOL is that when echo'ed out, it represents a \n
character.
The value you are working with might be \n\r or just \r
Others: correct me if I'm wrong, but...
Linux, BSD, etc... use \n as line endings
Windows (All versions) use \r\n
Mac (Old school) used \r
Mac (Current) BSD Style \n
But, with all that said. Here is the code a little further broken out.
?php
$parts = preg_split('|[\n\r]+|', $item['unitprice']);
if ( count($parts) 1 ) {
$dirty_price = $parts[(count($parts)-1)];
} else {
$dirty_price = $parts[0];
}
$clean_price = number_format($dirty_price, 2);
?
Any idea why PHP_EOL didn't work? If I could get it to work, I
could remove the trim function and 2 of those parentheses, which would

Frank:
I came to this thread a little late, but the following are some
functions I use, namely right(), left() and mid(). These were
built-in functions in different language I used many years ago. They
just seemed natural to me so I wrote them for php.
Cheers,
tedd
-
?php
// == returns the right-most number of characters from a string
// $string = 123456789
// right($string, 3) returns 789
function right($string, $length)
{
$str = substr($string, -$length, $length);
return $str;
}
// == returns the left-most number of characters from a string
// $string = 123456789
// left($string, 3) returns 123
function left($string, $length)
{
$str = substr($string, 0, $length);
return $str;
}
// == returns the middle number of characters from a string
starting from the left
// $string = 123456789
// mid($string, 3, 4) returns 4567
function mid($string, $left_start, $length)
{
$str = substr($string, $left_start, $length);
return $str;
}

Subject: [PHP] RIGHT Function?
Hi all,
I could use some help. I've scoured both the MySQL and PHP sites that I
know of and can't find an answer to this.
I have a price field that sometimes contains entries like this:
250,(min)
5.32
regex? If 250,(min)5.32 is in your row data, how do you sort price
ascending/descending?
How can I pull just the price ($5.32 in this example) from this field to
display on a web page? Is there a RIGHT function in PHP? When I search the
PHP
site, I'm being told there isn't one.
Here's the code I've been using:
itemid='WR-1240',$db);
printf('List: $%s
', number_format(mysql_result($result,0,priceList),2));
printf('Your Price: $%s',
number_format(mysql_result($result,0,unitprice),2));
?
Thanks,
Frank
