PHP - Make A Number Readable
Hi All,
Sometimes after some calculation php may return this: 1.02563125481E+54 But how to make this into 1 number without the E+ etc ?! Cheers Similar TutorialsHi Guys, I need a function which makes huge numbers normally readable... For example 1000000 must become 1.000.000 The same with smaller or lager numbers... Does someone know a simple solution ? Cheers hello, if i have $big=3410 how can i take the last 2 digits of that to make it so that i only get the 10? hope this makes sence. This is my preg_match code:
preg_match("/(\d+)|(T)|(A)/", $link, $matches, PREG_OFFSET_CAPTURE, ($off-30)
It works and matches the number I want, except it only returns the first character in the $matches array. For instance, if the number it finds is 10, it only returns 1. Now I understand that is what preg_match does, but how would I make that regex ungreedy? I tried adding a *, but it just made an error, and preg match all would keep searching for strings after the first one. All I want is for the first number, regardless of the length of it, to be returned in full. Thanks for any help.
<ul> <!-- List the rest of the articles found in the category --> <?php else : ?> <li class="otherrecentmain"><span class="title"><a href="<?php the_permalink() ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></span> <span class="meta"></span> </li> <?php endif; ?> <?php endwhile; ?> <!-- END --> </ul> For some reason, its stuck on displaying 9 articles but I want to be able to control how many I want. I may want to choose 17 or whatever etc, not sure how to add it into the php. I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params:
$params = array(
':user_id' => $userid,
':recipient' => $this->message_vars['recipient'],
':subject' => $this->message_vars['subject'],
':cc_email' => $this->message_vars['cc_email'],
':reply' => $this->message_vars['reply'],
':location' => $this->message_vars['location'],
':stationery' => $this->message_vars['stationery'],
':ink_color' => $this->message_vars['ink_color'],
':fontchosen' => $this->message_vars['fontchosen'],
':message' => $messageInput,
':attachment' => $this->message_vars['attachment'],
':messageDate' => $date );
Here is my sql:
$sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);";
And lastly, here is how I am calling it:
$dbh = parent::$dbh;
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
if (empty($dbh)) return false;
$stmt = $dbh->prepare($sql);
$stmt->execute($params) or die(print_r($stmt->errorInfo(), true));
if (!$stmt) { print_r($dbh->errorInfo()); }
I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong?
How do I write a bit of code to check if a file is NOT readable...and if (and only if) it is NOT readable (doesn't exist) , wget the file. Here's what I tried...but it loops forever and ever...even if the file does exist. Code: [Select] $filename = "file.mp3"; while(!is_readable($filename)) { $url = "domain.com" . ".mp3"; echo system('wget '.escapeshellcmd($url)); echo system('sleep 30'); } ?> I Googled...and couldn't find the correct syntax for IS NOT READABLE.

I'm getting data from a third party API and the first_name and last_name fields from this third party are sometimes not in english and they come out quite odd looking. Example... "first_name": "Pesh\u042fo", "last_name": "\u062d\u0633\u064a\u0646" How could I normalize that using PHP to make it readable again? Hi, I have a date and time stored in a database field (publishdate) and I'm using php to fetch it and display it in an HTML table. Only problem is it shows up in epoch time. I can't get it to display in human readable time for some reason. Here's the code I'm using (it's automatically generated by some software) // View column for publishdate field $column = new TextViewColumn('publishdate', 'Publishdate', $this->dataset); $column->SetOrderable(true); Many thanks in advance. Tony Hi, I have a connection set up to an API using a PHP script - the API sends back data in JSON format, and if I capture it and echo it, it displays in extremely unfriendly format on the screen. I've tried to find a way to convert this data into readable format, ideally in a HTML table, but although there are articles on converting manually inputted JSON data into a HTML table using Javascript, I can't find a way to do it from a PHP variable. This is what I have so far:
if ($_POST['getcompany']) {
$companyname = $_POST['_Name'];
$ch = curl_init();
$data_array2 = array(
'token' => $token
);
$make_call2 = json_encode($data_array2);
//echo 'Token is '.$token;
$token2 = substr($token, 14);
$token3 = substr($token2, 0, -3);
//echo 'Token 2 is '.$token3;
//echo 'Company Name is '.$companyname;
//curl_setopt($ch, CURLOPT_GET, 1);
//curl_setopt($ch, CURLOPT_POSTFIELDS, $make_call2);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Authorization: '.$token3.''));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://connectionurl?countries=GB&name='.$companyname);
//Execute the request
$result = curl_exec($ch);
echo 'Companies: '.$result; //This displays the data provided by the search, but is in JSON format
So I need a way to get the data held in $result, into a HTML table. Any idea how I can do this? Hello,
I have problem durring binding update query. I can't find what is causing problem.
public function Update(Entry $e)
{
try
{
$query = "update entry set string = $e->string,delimiter=$e->delimiter where entryid= $e->id";
$stmt = $this->db->mysqli->prepare($query);
$stmt->bind_param('ssi',$e->string,$e->delimiter,$e->id);
$stmt->close();
}
catch(Exception $ex)
{
print 'Error: ' .$ex->getMessage();
}
}
When I run function update I'm getting next error:Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement
Can you help me to solve this problem ?
Edited by danchi, 17 October 2014 - 10:25 AM. I need to display a number(the number is retrieved from the db) in the form input field such that only the last 4 digits is visbile, the remaining can be masked as * or X or whatever is applicable. I know the last 4 can be obtained as follows: Code: [Select] $number=substr($number,-4,4); But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format. Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number. Code: [Select] <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>"> Hey I have a string that looks like the following: Quote top-php-tutorials-2.html I have a script that cycles through each page. The 2 in the quote above is the page number. How can I extract the number between the - and the .html and replace it with another number? I've tried Code: [Select] substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long Any input would be appreciated hello, i have a start time and an end time (no dates). the following works great, except for when the start time is at night, and the end time is in the morning. im thinking if i can do an if the number is negative, add 24, that it will resolve my issue. any ideas? Code: [Select] $tbilled = $tfinish - $tstart; Okay so my news script is set to view only 10 pieces of news. But I want it so that it starts a new page once I have more than 10 pieces of news. Code: [Select] <?php require("functions.php"); include("dbconnect.php"); session_start(); head1(); body1(); new_temp(); sotw(); navbar(); $start = 0; $display = 10; $query = "SELECT * FROM news ORDER BY id DESC LIMIT $start, $display"; $result = mysql_query( $query ); if ($result) { while( $row = @mysql_fetch_array( $result, MYSQL_ASSOC ) ) { news_box( $row['news'], $row['title'], $row['user'], $row['date'], $row['id'] ); } mysql_free_result($result); } else { news_box( 'Could not retrieve news entries!', 'Error', 'Error', 'Error'); } footer(); mysql_close($link); ?> I tried a few things but they failed....miserably. $looponce = 1; foreach ($this->info as $k => $v) { if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) { for ($i = 0; $i <= 0; $i++) { $output[] = $this->display_errors('error_system_subject'); } } if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) { $output[] = $this->display_errors('error_system_name'); $looponce++; } } That is my loop that i check things in. What i'm more interested in is the name if statement. If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s. I'm looking for ways to remove the need for program errors and just change them to what is needed to run. What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given. above code $this->info = $formdata; $formdata = array( 'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error. 'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'), ); Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way? Hi there, As the question says i tried several things but i can't work it out and my knowledge about php isn't that well. I have these numbers in an array: 14042 11130 10100 10100 9506 How can I add them all together? Was thinking about a while loop. Derp. >array_sum solved! Hi all, i have this records that coming from the database: 0 0 0 1 1 1 1 1 0 0 1 1 1 1 1 1 i want to build a loop that will do like that: if ($res==0) {$res11==number} if ($res was allready 0 ignore it) if ($res==1 ignore it and all other $res=1 and wait till it's $res=0 again if ($res==0 again) { $res11==newnumber } please guide me to doing that, im stuck! thanks |
