PHP - Intval Is Not Reading Decimals

Just looking to know if this is the proper way to implement this:

I need the below if to be true when any number between 100 and 1000 is the value of x, including say "105.55"

if($x>= 100 && $x <= 1000){
}


Basically I'm asking will a value of x with a decimal in it not cause the if statement to be true.

I want to find the first sentence in a string without counting decimals. Here is the code I have, but I still want it to display the decimals, but I don't want it to count as the end of a sentence.

$content = "This is my test string which is 3.5% of what I'm trying to do. This is only a test.";

Code: [Select]
function first_sentence($content)
 {
if(preg_match('/[0-9]+\.[0-9]/', $content, $num)) {
$number = "$num[0]";
$content = ereg_replace("$number","", $content);
}
preg_match('/^.*[^\s](\.|\?|\!)/U', $content, $match);
$string = $match[0];

$title_count = strlen($match[0]);
if($title_count > "6"){
return "$match[0]";
}
else {
$content2 = ereg_replace("$match[0]","", $content);
preg_match('/^.*[^\s](\.|\?|\!)/U', $content2, $step);
return "$match[0] $step[0]";
}}
Currently this is what it displays: This is my test string which is % of what I'm trying to do.
This is what I want it to display: This is my test string which is 3.5% of what I'm trying to do.

Hi - To me, this doesn't make sense.   My Order form uploads product weights in an array . If I echo out those weights they are fine ie 25.25

However, when I try to update the DB for some reason, the for loop strips out all but the first digit, so 25.25 becomes '2' or indeed if I had entered 9999999 it just '9' is entered in to the DB.

I have tried using number_format to pre-process the decimals, - but I get an error saying you can not use it in a write format.

Many Thanks to anyone who can help with this  !!


PS - I have abbreviated the below code for clarity:

Code: [Select]
$weight = $_POST['weight'];

        for ($i = 0; $i < $numloops ; $i++)

      {
       $sql ="
UPDATE `confirmedorder`
SET orderid = '$orderid[$i]', weight='$weight[$i]',status='finished', ordervalue='$ordervalue'
WHERE customerid = $customerid
";
$this->db->query($sql);
}

Hi there.

I am trying to display numbers if they have the numbers like:

number_format($price,2)

This gives us two decimal places i.e 7.23

Now thats fine, I would like to round the last two decimal places. I would like to make it 7.25, (rounding it from 7.23 to 7.25)

Similarly making:

12.44 to 12.45
33.18 to 33.20
52.13 to 52.15

So actually rounding the last two places. Coz obviously customers won't be able to pay 52 dollars 13 cents. So therefore rounding the last cent's (decimal part) making it to 52.15

Thank you.

All comments and feedback are welcomed.

Ok so say I have php do some calculations for me

Code: [Select]

$Value1 = 300;
$Value2 = 100000;
$FirstRatio = $Value1 / $Value2;

$Value3 = 8000;
$Value4 = 6000000;
$SecondRatio = $Value3 / $Value4;


$FirstRatio = 0.003
$SecondRatio = 0.0013

How would I go about doing these calculations and then sorting $FirstRatio and $SecondRatio and then it would take the highest ratio ($FirstRatio) and it would echo the value?

[xml]<category id="SOCMENEURASTVICLEA" order="26800">Aus. Victoria League</category>[/xml]

I have the above xml, I can read the category id, order but I dont no how to read the value "Aus. Victoria League"


foreach($description->children() as $category) {
foreach($category->attributes() as $a => $b) {
echo "<br/> -------- ";
echo $a,'="',$b,"\"\n";
} 
echo "category name" . $category->asXML();
}


the asXML() i have no idea what that is but am guessing I need thats where the php function which returns the value needs to go
Thank you

The following script just validates some form inputs, and then puts any errors inside an array.

I get this error: Fatal error: Cannot use [] for reading in C:\xampp\htdocs\Game\includes\validation.php on line 104

I've looked around, and this still does not make any sense to me.

public function ValidateEmail($email, $reemail){
/*
Sanatize.
User filter_var to validate.
Make sure both emails match.
Check if email already exists or not.
*/
  trim($email);
  strip_tags($email);
  mysql_real_escape_string($email);
  
  trim($reemail);
  strip_tags($reemail);
  mysql_real_escape_string($reemail);
  
if(!filter_var($email, FILTER_VALIDATE_EMAIL)){
  $this->valid = false;
  //Line 104 $this->error[] - "The E-Mail that you provided is not valid.";
} else {
  $this->valid = true;
}

if($email !== $reemail){
  $this->valid = false;
  $this->error[] = "The E-Mail's that you provided do not match.";
} else {
  $this->valid = true;
}
if(filter_var($email, FILTER_VALIDATE_EMAIL) && $email == $reemail){
  $checkmail = mysql_query("SELECT users.email, temp_users.email FROM users, temp_users WHERE email = '$email'");
  if(mysql_mum_rows($checkmail) == 1){
  // email is found, throw out error
  $this->valid = false;
  $this->error[] = "That E-Mail is already in use.";
  } else {
  $this->valid = true;
 }
}
  return $this->error;
}

Line 104 is commented out.

Thanks!

how can I read a url coming from another site by header('Location:')  command

PHP 5.3.8
XAMPP on Windows XP

I have an XML file that manages the input to an mp3 player on this page http://www.jimslounge.com/segovia/
The structure looks like this
Code: [Select]
<content>

  <auto_play>yes</auto_play>
  <loop>yes</loop>
  <volume>60</volume>

  <artist>
    <song_title><![CDATA[Bach - Suite No. 3 - Allemande]]></song_title>
    <artist_name><![CDATA[Andre Segovia]]></artist_name>
  <image_path>load/images/segovia.jpg</image_path>
  <mp3_path>load/songs/Bach - Suite No. 3 (for solo cello, arr. Duarte)- Allemande.mp3</mp3_path>
<url target="_blank"  open="yes">http://en.wikipedia.org/wiki/Andr%C3%A9s_Segovia</url>
  </artist>
  <artist>
      ...
with <artist> being the repeating element I want to be able to read and eventually write to
If I run this
Code: [Select]
$xml = simplexml_load_file("load.xml");
 var_dump($xml);
I get this
object(SimpleXMLElement)#1 (4) { ["auto_play"]=> string(3) "yes" ["loop"]=> string(3) "yes" ["volume"]=> string(2) "60" ["artist"]=> array(22) { => object(SimpleXMLElement)#2 (5) { ["song_title"]=> object(SimpleXMLElement)#24 (0) { } ["artist_name"]=> object(SimpleXMLElement)#25 (0) { } ["image_path"]=> string(23) "load/images/segovia.jpg" ["mp3_path"]=> string(74) "load/songs/Bach - Suite No. 3 (for solo cello, arr. Duarte)- Allemande.mp3"  ... [/color]
which is overwhelming

This cleans it up but doesn't give me the artist name and song name I'm looking for.

Code: [Select]
$xml = simplexml_load_file("load.xml");
echo $xml->getName() . "<br />";
foreach($xml->children() as $child)
  {
  echo $child->getName() . ": " . $child . "<br />";
  }

The Output:
content
auto_play: yes
loop: yes
volume: 60
artist:
artist:
artist:

 My experience with simplexml only goes back a couple of hours so I'm pretty inept at this point.  Any help will be greatly appreciated.

I just can't wrap my head around it, but I am trying to integrate weather into my website using NOAA.

1. Here is the NOAA page: http://forecast.weather.gov/MapClick.php?CityName=Mio&state=MI&site=APX&lat=44.663&lon=-84.1446
2. Here is the XML to that page: http://forecast.weather.gov/MapClick.php?lat=44.66300&lon=-84.14460&FcstType=dwml

Now what I want to do is to have PHP on my website that reads the XML from the NOAA site and create the "Forecast At A Glance". Possible or too challenging?

Hi People.

Here is a form that is supposed to read from my database.

My primary key is called "index" and I have about 300 records in the database.

I wanted to be able to view the records but when I load this page the "php" part is empty.  I simply get given a blank form.  I know it is connecting to the DB OK because I changed one letter in the password and then got a "can't connect to the database error" just to test it out.

Code: [Select]
<?php
$host = 'localhost';

$usr = "the_db_user";

$password = 'not_shared_on_forum';

$db_name = 'stranded';

function cr($string){
          $clean_string = str_replace("rn","<BR>",$string);
         return $clean_string;
}

//$id = 11;
if (!isset($id)) $id = $_GET['id'];

mysql_connect ("$host","$usr","$password") or die ('Error During Connect:<br>'.mysql_error());
mysql_select_db ("$db_name") or die ('Error Selecting DB:<br>'.mysql_error());

$read_query  = "select * from HelperFormData where index = '$id'";
$results = mysql_query($read_query);

$rs = mysql_fetch_array($results);

Hi there

I am working on PHP form which has an array named: $productOptions.

When I do:

print_r($productOptions);

it returns:
Array ( [124] => Array ( [optionId] => 124 [optionName] => acer aspire [optionListId] => 28 [dateCreated] => 2010-11-04 12:48:53 [enabled] => 1 [optionQtyId] => 84 [productId] => 40 [quantity] =>7 )
 [114] => Array ( [optionId] => 114 [optionName] => acer fast [optionListId] => 28 [dateCreated] => 2010-11-01 02:04:53 [enabled] => 1 [optionQtyId] => 83 [productId] => 40 [quantity] => 0 ) 

Now from this Array, I would like to check if the quantity if greater than Zero. so I tried:

if (productOptions[quantity] > 0){
echo "blah blah..."
}

But for getting the quantity, the part:

productOptions[quantity]

returns nothing. Am I doing this correctly?

Please reply.

Thank you
