PHP - Breaking One Cycle Of A Foreach
Hey guys,
How can i break just one cycle of a foreach loop. Example: $arr = array('0','1','2'); foreach ($arr as $value){ if($value == 1){ break from this iteration and continue onto next one} echo $value; } So the output should be 02 Similar TutorialsHello i would like to as a little help on how to proper format an foreach output into an HTML table. I have a small function inside an class, that will retrieve the data of an MySQL table and return the result in 1 array, Outside that function i can get the values displayed i only need to format it to show in an table here's what i have: function that gets the data Code: [Select] function getfansub(){ $subfanarray = array(); $query = mysql_query("SELECT * FROM anr_fansub WHERE 1"); while($result = mysql_fetch_array($query)){ $subfanarray[] = $result; } return $subfanarray; } Outside the funtion/class Code: [Select] $fansubarray = $mysql->getfansub(); VAR_DUMP( $fansubarray ); echo "<br><br>"; foreach($fansubarray as $name){ echo $name['FansubID'] ." ". $name['Designation'] ." ". $name['Website'] ." ". $name['tracker'] ." ". $name['irc'] ."<br>"; } The problem i have with the formating (i really dont know who i can do it) is when he reaches the IRC link he needs to open and close the td and tr brakets of the table. any help or tip is apreciated, thanks in advance I use foreach to echo a list of tags come out of an array as Code: [Select] foreach ($array as $tag) { echo "$tag,"; }This produces "tag1,tag2,tag3,". The problem is the last ",". How to tell the foreach loop to avoid including "," after the last sequence? Hello everyone i have a quick question to ask if i may. On my website i have a presentation video on my homepage, with another 1 just made. What i want to do is when people view my website they see the first video as usual but after that finishes i would like it to switch to the next video which will then replace the first video is that possible in php? I have developed a calendar app. You can add events to certain days, edit, delete them, etc. It works fine now but I'm trying to improve the adding event section. I would like to be able to have a form where there are "name_of_event" and "description" inputs and then display a input that would have a date-picker. I also want to have a link/button that says something to the effect of "add additional day" and then tie a javascript function to it so when it is clicked another date-picker input will pop up under the first, and they'll be able to add as many additional days as they like. I can't figure out how to write the php code that will cycle through only the date-picker inputs though. Something like the following Code: [Select] <?php $name = $_POST['name_of_event']; $description = $_POST['description']; foreach(datepicker_inputs as $date)// <-- part i need help with { mysql_query("INSERT INTO Events (name, description, event_date) VALUES ($name, $description, $date)"); } ?> anybody have ideas on how i can only cycle through the date inputs? I'm pretty sure i'm going to have the date input form name something like "date_1", "date_2", etc. This topic has been moved to Application Frameworks. http://www.phpfreaks.com/forums/index.php?topic=355772.0 I'm experimenting with a basic CRUD App. The table created by the code below renders, however when I view source, the last tag is the closing </tr> after the while loop finishes. There's nothing after that. No closing table, html, or body tags. I can't see what I've done wrong.

Edited by Ch0cu3r, 13 November 2014 - 01:07 PM. Added code tags I have a site that everything was typed manually, but I want to get all this info off so I can put all info into a database for easier editing and so forth.
I'm trying this code, which works to a point.
function curl($Url){
if (!function_exists('curl_init')){
die('cURL is not installed. Install and try again.');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $Url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
$start = strpos($output, '<h2 style="text-align: center;"><span style="text-decoration: underline;">Alabama Tattoo Shops</span></h2>');
$end = strpos($output, '<p>', $start);
$length = $end-$start;
$site = substr($output, $start, $length);
$site = explode("<p>", $site);
foreach ($site AS $line) {
print_r($line);
}
return $output;

I am trying to break down the tables i have on my website in order to place them into my mySQL database. I am new to php and have been having some trouble and any help would be greatly appreciated. So far I have this but it doesnt seem to be working. I am using DOMDocument but I wonder if maybe preg_match woulf be better? Fatal error: Call to a member function getElementsByTagName() on a non-object in D:\Hosting\5915198\html\2.php on line 11 <?php // Load html string $dom = new DOMDocument(); $dom->loadHTML('www.empirebuildingsestate.com/company.html'); // Get tables from html $tables = $dom->getElementsByTagName('tr'); // Get rows from tables $rows = $tables->item(0)->getElementsByTagName('td'); // Loop over each row foreach ($rows as $row) { // Get each column by tag name $cols = $row->getElementsByTagName('td'); // Echo values (here you can assign them in array for example) echo $cols->item(0)->nodeValue.'<br />'; echo '<hr />'; } ?> What is the best way to break up repeating code? Make each page from a standard template (e.g. Header, Columns, Footer) and include the variable content using PHP?? Or make each page a stripped down PHP page which creates the variable content and then Includes the static parts (e.g. Header, Columns, Footer)?? Hope you follow me?! :-/ Debbie If I break up this long line of code will it still work correctly? Original... Code: [Select] define('WEB_ROOT', ENVIRONMENT === 'dev' ? 'http://localhost/example.org/' : 'http://example.org/'); Desired... Code: [Select] define('WEB_ROOT', ENVIRONMENT === 'dev' ? 'http://localhost/example.org/' : 'http://example.org/'); Or maybe... Code: [Select] define('WEB_ROOT', ENVIRONMENT === 'dev' ? 'http://localhost/example.org/' : 'http://example.org/'); Debbie Hoping someone can help me on this, but I had some help on getting this code (or part of it) to finally work the way I wanted it, however, there are a few end-user issues with it now. What this code does is disables the user(s) from posting any kind of links (www.example.com or example.com). However, now I'm trying to....expand it a little I guess. Here is the current code: Code: [Select] if (stristr($pagetext, 'http://') OR stristr($pagetext, 'www.') OR stristr($pagetext,'@') OR stristr($pagetext, '[URL') OR stristr($pagetext, '[url') OR stristr($pagetext, '[IMG') OR stristr($pagetext, '[img') OR preg_match("#[a-z0-9]([-a-z0-9]+)?(\.[a-z]{2,3})?(\.[a-z]{2,4})#i", $pagetext)) { more code here } Now, I KNOW what most of that code does, but what I need, is what exactly this code does: Code: [Select] preg_match("#[a-z0-9]([-a-z0-9]+)?(\.[a-z]{2,3})?(\.[a-z]{2,4})#i", $pagetext)Can anyone break this down and tell me what exactly does what? Thanks in advance hi gang, I just spent the better part of the day trying to find a way modularize my PHP code. I want to execute a php file and load the results into my main php program. I am not looking to include php source code into my prog and then execute it, I want to execute it and load the results into my prog. I know I can do this if I call a php file via apache: using file(http://ww.site.com/blah.php?parms) but is there a way to do it without using http ? The php file is local - in the same directory. I want something like this: $r = something.php?parms... how do I do this? regards, david If i have a list of categories like: 1. Billboards and advertisement section 1(a)City Clock 1(a)(i)Application fee (has columns for approved price and proposed price) 1(a)(ii)Advertisement Per year (has columns for approved price and proposed price) 1(b)Billboards 1(b)(i)Application fee for construction (has columns for approved price and proposed price) 1(b)(ii)Charge per year without advertisement (has columns for approved price and proposed price) 1(c)Something here..... 1(c)(i) something here...(has columns for approved price and proposed price) 1(c)(ii)something here...(has columns for approved price and proposed price) 1(c)(iii) something here... (has columns for approved price and proposed price) e.t.c THEN SOME CATEGORIES LOOK LIKE:category 2 2. Category name 2(a)something here..(has columns for approved price and proposed price) 2(b)something here.. 2(b)(i)something here..(has columns for approved price and proposed price) 2(b)(ii)something here..(has columns for approved price and proposed price) NOW: i have categories without sub categories and others with sub-sub categories , a main category doesn't does have a column for prices ( or lets just say other columns) , a sub category WITHOUT its sub category will have columns for prices, if a sub category has its sub category, then its subcategory should have columns for prices (this is where my problem is - how do i handle such a situation in php Mysql?? ) I have gold data being reported here goldprices.org.uk (scroll down near the bottom). Recently it broke for no apparent reason. I checked the scraper and everything seems to be OK. The issue is that the gold price in (troy) ounces is being scraped fine - however to work out the price in grams you must multiply by 0.0321 (grams in a troy ounce). The code looks like this: Code: [Select] $ounce_price = null; $grams_price = null; if(count($nodes) == 1 && $nodes[0][1]) { $ounce_price = $nodes[0][1]; $grams_price = $ounce_price * 0.0321; However $ounce_price * 0.0321 breaks the code and returns '0.0321'. I then tried the code: Code: [Select] $ounce_price = null; $grams_price = null; if(count($nodes) == 1 && $nodes[0][1]) { $ounce_price = $nodes[0][1]; $grams_price = $ounce_price + 1; And the code returned the value '2'. So it appears that when $ounce_price is being multiplied/subtracted etc it reverts to a value of '1'. However if I do $grams_price = $ounce_price the value is the correct ounce price. I'm so confused as to why when adding an equation to $ounce_price the value reverts to '1' as opposed to equalling the correct number. Any help here would be HUGELY appreciated - I've been stuck for several days and only just decided to ask online :s Nick First of all... this is a GREAT forum. Been lurking around here for a long time and searched all over but still can't find a solution to a problem I'm facing. Here's my cURL code - I am basically retrieving data from a web site: <?php $curl_handle=curl_init(); curl_setopt($curl_handle,CURLOPT_URL,'http://myprimemobile.com/update.html'); curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,2); curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,1); $buffer = curl_exec($curl_handle); curl_close($curl_handle); if (empty($buffer)) { print "Connection Timeout<p>"; } else { print $buffer; } ?> If you take a look at the site http://myprimemobile.com/update.html -- it will begin to update new information. I want to basically retrieve the data from that page but in my own way. I want to loop through the page and search for all the names, addresses, and phone numbers only (not store hours or anything else), and want to put it in a variable so I can create a table with all that information on my page. Based on the code, all the information is stored in the $buffer variable. I want to break this variable down to extract certain data in a 'div' or a 'table'. Please help me out. Thanks! Hi guys, So here is the deal. We have a list of brands that excists in a database. There are also images associated with the names. But not all the brands have images. So in the script i read if the file excists. Well this all works fine but it looks horrible. So i want to break the list in half (or limit it to 24). But i cant limit the sql query. Is there a way to "limit" a while loop and let it resume on the same page, just to change the layout (multiple collumns)? (I hope i am clear on this... i confuse even myself) $host = 'localhost'; $user = 'qwerty'; $pass = 'qwerty'; $db = 'qwerty'; $query = "SELECT * FROM ros_brands"; $result = mysql_query($query) or die(mysql_error()); $filename = "/resources/images/mm_files/" . $row['image_file_id'] . ".gif"; while($row = mysql_fetch_array($result)){ $filename = "/var/www/vhosts/test.nl/httpdocs/resources/images/mm_files/" . $row['image_file_id'] . ".gif"; if (file_exists($filename)) { echo "<a href='#'><img src='/resources/images/mm_files/" . $row['image_file_id'] . ".gif' /><span>". $row['name'] ."</span></a>"; } else { // echo "The file $filename does not exist"; } } Hi all, In order to teach myself php I am developing a simple cms system to display my graphic design work. Basically I am working on developing a simple portfolio website powered by a custom made CMS. So far, I can create new posts which are being stored in a MySQL db. My index page runs a sql query to get the latest posts and sorts them by category. Currently the results look like this: Quote Title1 Category A Text Title2 Category A Text Title3 Category B Text Title4 Category B Text The code to generate this looks like this: $content = mysql_query("SELECT * FROM posts ORDER BY category, date DESC"); while($row = mysql_fetch_array($content)) { echo '<h2 class="post_title">'.$row['title'].'</a></h2>'; echo '<p class="cat">category: '.$row['category'].'</p>'; echo '<p class="post_body">'.$row['body'].'</p>'; echo '<p class="image">image: '.$row['image'].'</p>'; echo '<p class="lowerlefttext_metainfo">by <span class="lowerlefttext_author">'.$row['author'].'</span> on '.$row['date'].'</p>'; } What I would like however is this: Category A Title 1 Text Title 2 Text Category B Title 3 Text Title4 Text I am not sure how to do this elegantly without having to code an sql query per category, which I don't think is efficient? Thank you! This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=343488.0 Hello everyone, I am trying to see if a term, sent from a form, is in an array that has been pulled from the database. The problem I am having is that while the terms look the same the one from the database is using an Ascii character for a forward slash. & # 047 ; I have tried adding the Ascii to the form value but it just rendered as a forward slash (no surprises there I suppose) So the main reason for asking is that for all the other items in the form I can use in_array. This keeps things really tidy and easy to use. Any ideas how I can still use in_array and get around the Ascii problem? Cheers Ian |
