PHP - Extracting A Paragraph (minus The Html)
Hello
$row[longdescription] contains a description of a product (complete with HTML mark-up). I would like to display the first 250 characters in the results of a search. I would also like to remove any images that may crop up. This is what I have so far... Code: [Select] echo strip_tags(html_entity_decode(substr(preg_replace('/<img[^>]*>/Ui', '', $row[longdescription]), 0, 250))); The thing is (as you guys can probably already see), it also counts the HTML mark-up as characters and I get very different outputs (especially if an image occurs). I'd appreciate if you could advise me as to the correct way of doing this. Thank you Similar TutorialsHi Can someone point me in the right direction. I can force php to put a Plus(+) sign in front of positive numbers with printf('%0+4.2f',$x) But I cant get this to work inside <option>printf('%0+4.2f',$x)</option> tags Any help is greatly appreciated. hi , i want to select qty from master where id=$id , then i want to minus the qty = qty -1 and update in the query . here is my code . can tell me what went wrong ? Code: [Select] $query= "SELECT qty FROM master where id=$id"; $result = mysql_query($query,$dblink); while($myrow = mysql_fetch_row($result)) { qty -= 1; $query = "UPDATE master SET qty='$qty' WHERE id= $id"; $result = mysql_query($query,$dblink); } thanks Hi I'm using SimpleXMLElement to work with a supplied XML file, problem is with the way the XML document is formatted. The document uses '-' (minus) in the element names instead of _ so when I go to read the values, nothing is returned: Code: [Select] $developer->developer-region; //returns nothing However if I change the sample XML document that I've been supplied to <developer_region></developer_region> and do Code: [Select] $developer->developer_region; //returns child elements This is not practical to manually change the document, is there a way to use '-' in the xml document? Thanks in advance Ste Hi all I have a string called $voucher_code which is a value used to deduct or add value to a shopping cart. If the value is a minus I need it to show the minus sign, or if it's a plus value, it needs to show a plus sign. Here's my code: <strong>£ -".number_format(($voucher_code),2)."</strong> How do I modify the above code to show + instead of -- which it does at the moment? Many thanks for your help Pete Hi, I'm having trouble with this: Code: [Select] $date = date('d/m/y') ; echo $date; echo "<br/>"; $date1 = strtotime('date -1 month'); echo date('Y-m-d', $date1); My result looks like this: Current Date: 19/05/11 Date minus 1 month: 1970-01-01 I want it to look like this: Current Date: 19/05/11 Date minus 1 month: 2011-04-19 Hey guys, Was wondering if someone could point me on the right path here. I am able to get the page URL using: $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; But was wondering if there was a way to drop the PHP variables attached to the URL. e.g. mysite.com/catalogue/?item=23 becomes mysite.com/catalogue/ Can anyone help me out? Thanks! Hi all I'm building a script which reads a XML document, and so far so good... until now! the document uses '-' extensively all the way through it (not something that I would have chosen) so to combat this I've used {}. The part of the document I am working on now, this simply does not work, and I really cannot see why... XML Code: [Select] <plot> <name-number>87</name-number> <price>183000</price> <bedrooms>4</bedrooms> <status>available</status> <summary>With three double bedrooms, including one en suite and a further bedroom plus family bathroom to the first floor,&nbsp;separate lounge and&nbsp;dining room with kitchen&nbsp;and utility to the ground floor, the Otter is a modern home with a great deal to offer growing families.</summary> <feature>Separate lounge and dining room</feature> <feature>Kitchen with utility room</feature> <feature>Integral garage</feature> <feature>En suite to master bedroom</feature> <property-type>detached-house</property-type> <media> <caption> </caption> <type>image</type> <filename>1855_Otter-WhitehirstGrange.jpg</filename> <indexno>1</indexno> </media> <media> <caption> </caption> <type>floorplan</type> <filename>1386_Otter-WhitehirstGrange.pdf</filename> <indexno>2</indexno> </media> <media> <caption> </caption> <type>brochure</type> <filename>284_brochure.pdf</filename> <indexno>3</indexno> </media> <style-name>Otter</style-name> </plot> PHP Code: [Select] echo $plot->{name-number}; // echoes nothing, should echo 87 echo $plot->price; // echoes 183000 echo $plot->bedrooms // echoes 4 echo $plot->{style-name} // echoes nothing, should echo Otter This is frustrating the hell out of me, and I cannot see why this would work everywhere else in the XML document but not here. Any ideas or help would be received with gratitude! Hello, I've been struggling for days on this problem now. And I'm getting frustrated! I know that the answer is simple, and I've done it before but I cannot figure out what I'm doing wrong. What do I want? Well, I get a date from the database in this format: YYYY-MM-DD. I first want to distract one month from that and then set in into this form: YYYY, MM, DD. I've got this but it's not working (I've tried a lot different values). $transformdate = date("Y-m-d", strtotime("-1 month", $d_datevalue)); $startpoint = str_replace("-", ", ", $transformdate); Thanks, NLCJ I insert a time value using the following code
$ti= ( !empty($_POST['time']) ) ? "'{$_POST['time']}'" : 'NULL';
I want to insert a second time value into a differen column which would be the same time minus 1 hour
something along the lines of :
$ti2= ( !empty($_POST['time']) ) ? "'{$_POST['time'] -1 hour}'" : 'NULL';
What would be the correct way to do it
Hi, I am a beginner with php and I am having a hard time understanding a section in my code. The part I dont get is why we have to minus 1 from the number being passed into the array. For example, $FaceNamePlural[$die1-1] I tried looking at it over and over but I'm still very confused. Can anyone help me on this...Thanks. Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Untitled Document</title> </head> <body> <?php $FaceNameSingular = array("one", "two", "three", "four", "five", "six"); $FaceNamePlural = array("ones", "twos", "threes", "fours", "fives", "sixs"); function CheckForDoubles($die1, $die2) { global $FaceNameSingular; global $FaceNamePlural; if($die1 == $die2) // doubles echo "The roll was double ", $FaceNamePlural[$die1-1], "<br />"; if($die1 != $die2) //not doubles echo "The roll was a ", $FaceNameSingular[$die1-1], " and a ", $FaceNameSingular[$die2-1], ".<br />"; } function DisplayScoreText($Score) { if($Score == 2) echo "you roll snake eyes! <br />"; if($Score == 3) echo "you roll loose duece! <br />"; if($Score == 5) echo "you roll fever five! <br />"; if($Score == 7) echo "you roll natural! <br />"; if($Score == 9) echo "you roll nina! <br />"; if($Score == 11) echo "you roll yo! <br />"; if($Score == 12) echo "you roll boxcars! <br />"; } $dice = array(); $dice[0] = rand(1,6); $dice[1] = rand(1,6); $Score = $dice[0] + $dice[1] ; echo "<p>"; echo "The total score for the roll was $Score . <br />"; CheckForDoubles($dice[0],$dice[1]); DisplayScoreText($Score); echo "</p>"; ?> </body> </html> Hiya! I have a file (see attached) that contains basic HTML for a page with multiple paragraphs. How do I check the length of each paragraph to find out if it is 30 characters or over? If the first paragraph is not equal to 30 characters, then it should move on to the next one, and so on. If a paragraph is found to be the correct length, I then need to extract the text from the <p> tags. If a none of the paragraph match 30 characters in length, then the code will need to choose the best length paragraph. Any help is greatly appreciated. Many Thanks, FishSword From what I understand we can use ucfirst to convert the first letter within a string to upper case. What I would like to know is if there is a function that exists that would convert the first letter of every paragraph to upper case. For example: From: Code: [Select] This is a paragraph. is this the car blue? let's go for a pint of beer! To: Code: [Select] This is a paragraph. Is this the car blue? Let's go for a pint of beer! Does any such function exist? Folks, I want to extract certain portion form URL. Exmaple: Quote http://abc.com/this-is-test.html Output should be Quote this-is-test Another Example Quote http://abc.com/this-is-yet-another-test.html Output should be Quote this-is-yet-another-test I am not sure how it can be done with preg_match() and regex or something like that... Can someone help me with this please? Cheers Natasha I have an RSS feed, with alot of data of lottery numbers. the feed itself is : http://www.alllotto.com/rss/NY/latest.rss The item i am interested in is: Quote <item> <title>Take 5</title> <description>2011-08-27: 4, 10, 16, 17, 31</description> <guid isPermaLink="false">USA-New-York-Take-5-2011-08-27</guid> </item> How could I output those to varibles? thanks Joe I usually only do design work, but a client wanted a log in system to his website, so I decided to do it. I set everything up correctly, and users can sign up, login, and log out. However, he wants to be informed when a user logs into his site. So say (user x) wants logs in, my client wants to receive an email with all of (user x)'s account information. How do I pull a row from mysql based on the login information provided? My database is has 7 columns: user, pass, name, address, state, phone, email Hey guys i have a array i made and im wanting to grab a random value out of the array. The only way i can see to do this looking at the list of array functions is i need to random a key first? and then return the value assigned to the random key i just generated? I only see a function that lets me do the opposite. array_search() so now that i have generated a random key how do I grab just the value from the array using the random key. or is there a function i can just random value? $explode_names = explode(" ", $planet_names); $random_key_name = (array_rand($explode_names, 1)); echo $random_key_name; HI guys, I'm quite new to php, and I'm really struggling to get this right. I just cant get it to work properly. Im trying to extract email from a list of URLS. I have currently got it to work with 1 URL at a time, but I am needing to as to how I can pass multiple URLS at once, either from a csv or just pasting them into the input. any help would be much appriciated. here is my current code: Quote <?php $the_url = isset($_REQUEST['url']) ? htmlspecialchars($_REQUEST['url']) : ''; ?> <form method="post"> Please enter full URL of the page to parse (including http://):<br /> <textarea name="url" cols="100" rows="10"><?php echo $the_url; ?></textarea> <br /> <input type="submit" value="Get Emails" /> </form> <?php if (isset($_REQUEST['url']) && !empty($_REQUEST['url'])) { // fetch data from specified url $text = file_get_contents($_REQUEST['url']); } elseif (isset($_REQUEST['text']) && !empty($_REQUEST['text'])) { // get text from text area $text = $_REQUEST['text']; } // parse emails if (!empty($text)) { $res = preg_match_all( "/[a-z0-9]+([_\\.-][a-z0-9]+)*@([a-z0-9]+([\.-][a-z0-9]+)*)+\\.[a-z]{2,}/i", $text, $matches ); if ($res) { foreach(array_unique($matches[0]) as $email) { echo $email . "<br />"; } } else { echo "No emails found."; } } ?> hey guys i need to extract all the IP's of a string and loop them for more operations but for some reason i only get the first one <?php $string = '80.37.14.13 80.37.14.14 80.37.14.15'; preg_match("/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}/", $string, $matches); foreach ($matches as $ip){ echo "$ip<br>"; } ?> The string is not really seperated by spaces ... it can actualy be messy and have ips rapped arround a lot of code. The regex works because i do get the first one ... What did i miss? Hi there I need to extract data from some XML. I have found a few sites that explain that part to me, however there is a section of the data which I need to extract and am not sure how to go about it. Below is an extract of the XML, the section I am trying to extract is highlighted in red (it is essentially a text message being sent I am trying to get the contents of the sms/text message): <usa_smpp_host>THTTP</usa_smpp_host> <short_message>id:660352946 sub:001 dlvrd:001 submit date:1102081032 done date:1102081035 stat:DELIVRD err:000 text:Test SMS message</short_message> <dest_addr_npi>1</dest_addr_npi> Any assistance would be appreciated. Have played around quite a bit but have not managed to figure it out yet. thanks |
