PHP - Just Wondering Something About Extract()
What is the difference between EXTR_PREFIX_SAME and EXTR_PREFIX_IF_EXISTS?
Similar TutorialsThis topic has been moved to Third Party PHP Scripts. http://www.phpfreaks.com/forums/index.php?topic=321546.0 So I have been working on my website for a while which all is php&mysql based, now working on the social networking part building in similar functions like Facebook has. I encountered a difficulty with getting information back from a link. I've checked several sources how it is possible, with title 'Facebook Like URL data Extract Using jQuery PHP and Ajax' was the most popular answer, I get the scripts but all of these scripts work with html links only. My site all with php extensions and copy&paste my site links into these demos do not return anything . I checked the code and all of them using file_get_contents(), parsing through the html file so if i pass 'filename.php' it returns nothing supposing that php has not processed yet and the function gets the content of the php script with no data of course. So my question is that how it is possible to extract data from a link with php extension (on Facebook it works) or how to get php file executed for file_get_contents() to get back the html?
here is the link with code&demo iamusing: http://www.sanwebe.c...-php-and-jquery
thanks in advance.
Hey guys wondering if this is possible or not im wanting to add the b_x with the b_y so i select it out of the data base as 1 number. The math im really going to do is more complex but just using add to simplifly what i want to do. i would obviously need to assign it in some way so I can grab it to like $variable = $star_check1[]; This will acctually become a loop grabing several rows so if i could change it into one number would be alot easier. $star_check3 = "SELECT b_x,b_y FROM planets WHERE x = '".($x)."' AND y = '".($y)."'"; $star_check2 = mysql_query($star_check3) or trigger_error("SQL", E_USER_ERROR); $star_check1 = mysql_fetch_array($star_check2); Just wondering if I have an if statement like: if ( true || true || true ) { // do this } Is PHP clever enough to do this: if ( true || skip_me|| skip_me) { // do this } if ( false || true || skip_me ) { // do this } Like precedence for the leftmost conditions? Thanks for any help. I don't know if this is the correct type of question to ask here - I built a sandbox about 3 months ago with the latest XAMPP. I know that it came with PHP 5.x [5.2 I think]. I am not at home right now to check it. I just found out that the host server is running 4.4.9. I have no control over the host, or host selection. I am going to attempt to get a database online using basic [I hope] PHP scripts to query the otherwise static database. Are there major differences in the versions that I need to watch out for? I realize that I will now have to get 4.4.9 installed on my sandbox. I plan on using Dreamweaver CS5 to get my pages built. The main site is built and managed by another person using Expression Web 2. I am also unaware if the master.dwt built in Expression can be somehow brought into my PHP for site consistency. I am open to all comments and suggestions. I have 2 pieces of different code that get run at different times, but act on the same text file. (The first example writes data and the second rewrites data with some expired data removed from the rewrite.) The first code example appends data to a new line each time it is run except when it is run just after the second code example has ran. When run after the second example, the first code example will append the data to the last line of the text file instead of appending to a new line. Why is this? Here is the first code example... Code: [Select] <?php $message = "Hello, World! \nGoodbye!"; $message_br = str_replace("\n", '<br />', $message); // couldn't use nl2br because i needed to remove the \n completely. $userName = "Anon"; $coordinates = "1234567890"; $locationType = "geo"; $dateDay = "23"; $dateMonth = "2"; $dateYear = "2011"; $timeHour = "9"; $timeMins = 45; $timeAMPM = "AM"; // Format the time/Date date_default_timezone_set('UTC'); $inputTime = date('c', mktime((int)$timeHour, (int)$timeMins, 0, (int)$dateMonth, (int)$dateDay, (int)$dateYear)); // Send all data so far, to an array. $entry_array = array(); array_push($entry_array, $inputTime, $locationType, $coordinates, $userName, $message_br); // write the array to CSV file. $fp = fopen('messages.txt', 'a'); fputcsv($fp, $entry_array, "|"); fclose($fp); ?> Here is the second... Code: [Select] <?php $one_day = 60*60*24; $timestamp = time(); date_default_timezone_set('UTC'); $expiry_date = date('c', $timestamp+$one_day); $future_date = array(); $delete_line = array(); // Open existing data in the text file. $lines = file('messages.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES); foreach ($lines as $line){ list($field1, $field2, $field3, $field4, $field5) = explode('|', $line); if ($field1 < $expiry_date){ array_push($delete_line, $line); // add to the to-be-deleted array. } else { array_push($future_date, $line); } } $array2string = implode("\n", $future_date); // convert array data to string. // write the data to CSV file. $fp = fopen('messages.txt', 'w'); fwrite($fp, $array2string); fclose($fp); ?> Hi, I have a form that I am trying to get working. The page is named "reserv_test.php". Not sure if I am trying to do to much, but can anyone tell me if this will work? If so, what do I need to do to make it work? Here is the code...

Am I doing something wrong in MySql. I have all eroors on , but i get NONE when running the script? I'm having a lot of trouble validating things using custom regex. I'm trying to validate usernames without spaces using numbers and/or letters with optional underscores. This is my code but it isn't validating anything, nothing is ever validated. Whatever I write it says the username isn't valid. if(isset($_POST['submit'])){ if(filter_var($_POST['value1'], FILTER_VALIDATE_REGEXP, array("options"=>array("regexp"=>"/^[\w.-]{{3},{28}}$/")))){ echo "Value is a valid username."; } else { echo "Value is NOT a valid username."; } } ?> Any help regarding this issue will be greatly appreciated.

I need to extract "C:\Documents and Settings" from the last line of this data every time it appears. It is always between DirectoryName REG_SZ and HKEY.

I am trying to extract the year from a date Code: [Select] 2012-03-01 echo "2012"; I have tried this and it only displays 1969 $dateorig = "2012-03-01"; $new_year = date("Y", strtotime($dateorig)); echo $new_year; How to extract the last row a query and store it in a variable ? Thanks for helping. Noob apppreciate. I have just noticed that I m allowed to use variables without using the extract function. like ; before : your name is $_POST['name']; now I m allowed to use ; your name is $name // I m not using here extract What can cause this ? How can I switch it off ? Any security problems I can face ? Hi, I got 1 warning form the server, It said:
Warning: extract() expects parameter 1 to be array, null given in /home/tz005/public_html/COMP1687/edit.php on line 113
extract($row);
how to fix the warning,should I replace it with extract($array);?
Hello, I am creating zip file of multiple files using PHP and downloading it. Problem is that: zip file is getting extracted by only WinRAR, its not getti ng extracted by default windows extracter or other software. Here is code which I have written -
$file_folder = 'referral-resume/'; Folks, Quote http://natty.com/p/bh-fitness-class-indoor-magnetic-exercise-bike-2-years-parts-/detail/b004r2wuak/fitness-spinning.html From this url String, i want to extract the last part of string which is, "fitness spinning". This URL is dynamic an can have any value in that last bit, so how to extract anything btween Two Forward slashes just before .html? Note: It can not be extracted with GET as its not how its designed. Thanks Natasha I draw contents from a database. Some of the texts contain a footnote, which is formatted using a div class. Following the HTML of this:
<div class=""footnotes"">
<br>
<hr align=""left"" noshade=""noshade"" size=""1"" width=""150"" />
<blockquote> <a href=""#f1"" name=""fn1""> <span class=""superscript""> * </span>
</a>Some footnotetext</blockquote></div>
Since my bibliography uses data from the database as well, the footnote now appears before the references, but I would like it at the very bottom of the page. I was thinking of using preg_replace in order to separate the textfield into two variables, one for the text itself, the other one for the footnote (it is always just one) and integrate after the bibliography is compiled.
Unfortunately, it seems that the preg_replace does not work. It always displays the whole content of the textfield. Here's the PHP:
$text = preg_replace('/(.*)(\div class=\"footnotes\"\>.*?\<\/div\>)/s', '$1', $result['text']);$footnote = preg_replace('/(.*)(\div class=\"footnotes\"\>.+?\<\/div\>)/s', '$2', $result['text']);
echo '<div align="justify"><span style="font-family:Georgia;font-size:16px;">' . $text;
***BIBLIOGRAPHY***
...
echo $footnote;
Maybe someone has an idea how to deal with that. I tried it on phpliveregex. There search string works fine. Many thanks for any help.
