PHP - Breaking Up Long Line
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 Similar TutorialsCode: Code: [Select] PostInfo,color-main,Newman,not-collapsed;Friends,color-main2,Top Friends,not-collapsed||Twitter,color-main2,Twitter,not-collapsed;Signature,color-main2,Signature,not-collapsed;AboutMe,color-transparent,About Me,not-collapsed Now I want make a function like if PostInfo = "not-collapsed" = do this/etc, So simply, how do I extract some content out of this and then use each thing to equal to if it's 'not-collapsed' or 'collapsed' ? Very hard but i think possible? ty 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 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 $cols->item(0)->nodeValue.'<br />'; echo '<hr />'; } ?> I have a site that everything was typed manually, but I want to get all this info off so I can put all info into a database for easier editing and so forth.
I'm trying this code, which works to a point.
function curl($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;
}
$site = curl('http://www.tattooshopusa.com/alabama/');
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 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 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! 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 $value; } So the output should be 02 Hoping someone can help me on this, but I had some help on getting this code (or part of it) to finally work the way I wanted it, however, there are a few end-user issues with it now. What this code does is disables the user(s) from posting any kind of links (www.example.com or example.com). However, now I'm trying to....expand it a little I guess. Here is the current code: Code: [Select] if (stristr($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 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?? ) what im trying to do is take a youtube embed code find the URL code for that video and remove all other parts of the code keeping only the URL of the video after i get the URL by it self then replace the http://www.youtube.com/ part of the URL with http://i2.ytimg.com/vi/ to do this i know that i need something like this to get the URL of the video http://www.youtube.com/((?:v|cp)/[A-Za-z0-9\-_=]+) but how to only return just the URL is something idk how to do then use str_replace http://www.youtube.com/(?:v|cp)/" with http://i2.ytimg.com/vi/ so in the end im asking if anyone know how to remove all other codes i dont want and only keep the URL this may have to be done using "regex" im not sure as i dont know to much about regex and what it can do but does sound like it would help lol 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"; } } 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 This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=343488.0 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! Dear All Good Day, i am new to PHP (a beautiful server side scripting language). i want to send a mail with line by line message i tried with different types like by placing the things in table and using <br /> but the thing is the tags are also visible in the message of the mail. Here is my code: $message1 = "Name :". $_REQUEST['name']."<br />"; $message1 .= "Surname :". $_REQUEST['surname']."<br />"; $message1 .= "Cellphone :". $_REQUEST['mobileno']."<br />"; $message1 .= "Telephone :". $_REQUEST['landno']."<br />"; $message1 .= "Fax :". $_REQUEST['fax']."<br />"; $message1 .= "Company :". $_REQUEST['company']."<br />"; $message1 .= "Email :". $_REQUEST['email']."<br />"; $message1 .= "Country :". $_REQUEST['country']."<br />"; $message1 .= "Enquity :". $_REQUEST['enquiry']."<br />"; $message1 .= "Date&Time :". $date."<br />"; For this code if try to print/echo it it is working fine it is displaying line by line, but using this variable ($message1) in the mail these <br /> are also visible. Can any one guide me to resolve(to remove these tags from the message part) this issue. Thanks in Advance. :confused: i have to read a single line from a csv, its a really big file and i only need one column.
i need the response to be a string ,i made a search and found the following code but i dont have any idea how to get a single line from a single string per run .
<?php
$row = 1;
//open the file
if (($handle = fopen("file.csv", "r")) !== FALSE)
{
while (($data = fgetcsv($handle, 0, ",")) !== FALSE)
{
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++)
{
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
?>
Edited by bores_escalovsk, 16 May 2014 - 06:38 PM. Hi. I want a simple textbox, that when submited, will replace very every new line, with the <br> tag. What will happen, when it submits, it will take the contents of a textbox, add the <br> tag where a new line is suposed to be, and save the string to a MySQL Database. I think this is the easiest way of allowing a user to edit what appears on a website when logged in, but if there is a easier way, then please tell me. What I am trying to do, is a login page, and once logged in, you enter new text into the textbox, click submit, and on the website homepage, the main text will change to what was submitted. But if there is a new line, I think the only way in HTML to make one is to put a <br> tag, so I want the PHP to but that tag wherever there is a new line. Sorry if I am confusing, I am not that advanced at PHP, but I would be very happy if you could supply me with the correct code. Time is running out... If you do not understand me, please tell me -- PHPLeader (not) |
