PHP - How To Find Certain Parts Of Text Within A File?
Hi, Everyone!
I have an issue and I'm not even sure if it can be done with PHP, but even this info would help me (to stop looking for an answer). I need to populate a (MySQL) database with stuff which is now written in a (HTML formatted) file. Here are my options: 1. Copy/paste each single field via PHPMyAdmin . 2. Write a little script to extract the necessary parts of text from these files to create a CSV-like content which I would then easily INSERT into the db. Example The files look like this: Code: [Select] <!-- SEPARATOR (same throughout the file(s) --> <tr><td> <div style="something"><img src="img/what_i_need_to_extract_1.png"></div> </td><td> <div style="something else"><b>What I need to extract 2</b></div> <div style="something else">What I need to extract 3</div> </td></tr> <!-- SEPARATOR (same throughout the file(s) --> etc ... and it goes like... 100 times in each file in the same standard pattern with the "What I need to extract" parts being completely different each time. Since it's possible to tell when each part required for extraction begins and ends, I would expect the script to look for these key-points (according to the example, it would be: img/ to "></d then "><b> to </b>< and else"> to </div>) and return a result like this (acc. to the example): ('what_i_need_to_extract_1.png', 'What I need to extract 2', 'What I need to extract 3'), (and so on...). Is it possible? Is there a function/option/way to look for a start/end-point like this and fetch the part between these two set points? If so - how? Any help would be appreciated, I'm not expecting a full code, obviously, just a point to the right direction or where to look at would be nice. Thanks in advance. Similar TutorialsI currently am working on a project where I code a "simple" telephone directory. There are three main tasks that it needs to do: 1. Directory.php(index page) has a "First Name" and "Last Name" field and a search button. When a name is searched from the directory.txt file, it displays First Name, Last Name, Address, City, State, Zip and phone in findinfo.php in designated text boxes...first name, last name, etc. 2. From the findinfo.php, like previously stated, the users information is listed in the appropriate text boxes. From there, there is an update button that will overwrite the user's information to directory.txt if that button is selected. It will then say the write was sucessful. 3. (completed this step) From the index page, there is a link that will take you to addnew.php where you enter First Name, Last Name, Address, City, State, Zip and phone in a web form and write it to directory.txt. This is the php code for the third step: <?php $newentryfile = fopen("directory.txt", "a+"); $firstname = $_POST['fname']; $lastname = $_POST['lname']; $address = $_POST['address']; $city = $_POST['city']; $state = $_POST['state']; $zip = $_POST['zip']; $phone = $_POST['phone']; $newentry = "$firstname $lastname\n\r $address\n\r $city, $state $zip\n\r $phone\n\r"; if (flock($newentryfile, LOCK_EX)) { if (fwrite($newentryfile, $newentry) > 0) echo "<p>" . stripslashes($firstname) . " " . stripslashes($lastname) . " has been added to the directory.</p>"; else echo "<p>Registration error!</p>"; flock($newentryfile, LOCK_UN); } else echo "<p>Cannot write to the file. Please try again later</p>"; fclose($newentryfile); if(empty($firstname) || empty($lastname) || empty($address) || empty($city) || empty ($state) || empty($zip) || empty($phone)) { echo "<p>Please go back and fill out all fields.</p>"; } ?> So to sum it all up, what would be my best approach? I am totally stumped and not sure which function to use. Should I work my way from step 1 to step 2? I see it as when I do the search for the name from directory.php, it takes me to findinfo.php, listing the users information in the text boxes. From there, if I needed to, having the user's information already listed I could hit the update button to overwrite the new information to directory.txt. Doing the update when then tell me that the write was successful. I have literally been scouring the internet for hours. What would be the best function to do this? I hope I was clear enough. Please help me out and thank you for your time. I wanted to replace a strings in a large text file .. what would be the fastest way ?! e.g the text file contains .. INSERT INTO `subjects` VALUES (1, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (2, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (3, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (4, 'some text here', 'some text here', 'some text here'); INSERT INTO `subjects` VALUES (5, 'some text here', 'some text here', 'some text here'); I wanted to replace the string " VALUES (1, " with "VALUES (" in each line .. I'm new in PHP so any response would be much appreciated .. thanks I am trying to eliminate this issue but I have had no luck here is my current code: Code: [Select] $from = 'help@my.com'; $body = "<html>\n"; $body .= "<body style=\"font-family:Verdana, Verdana, Geneva, sans-serif;\">\n"; $body .= $message; $body .= "</body>\n"; $body .= "</html>\n"; $boundary = uniqid('np'); $semi_rand = md5(time()); $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; $headers = "From: $from"; $headers .= "\nMIME-Version: 1.0\n" ."Content-Type: multipart/alternative;\n" ." boundary=\"{$mime_boundary}\""; $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/html; \n" . "Content-Transfer-Encoding: 7bit\n\n" . $body . "\n\n" . "--{$mime_boundary}--\n"; mail($to, $subject, $message, $headers, '-f'.$from); I have tried adding the plain text part but nothing has worked, could someone else look at this and show me what I need to add so that it has the text/plain MIME part as well? How can i find out parent (including) file of included file? Lets imagine that we want to for example auto_prepend file to each file on our server that would write out the name of file its being executed. I know, i can use PHP_SELF but what if i want to write name of file which is already included? I have a web page and i want on it show its name even if it was included, but not the included page itself is showing name but auto_prepend file to each php file, its duty of this auto_prepend_file to write it out i dont want myself to echo it on each page? do you feel me? I have short urls on the same page that this javascript code is on. the problem is that the code now can't find the poll.php. I have tried the full path and full url to the poll.php, but the code still outputs file not found. how to get this code working?
$.post('poll.php', $(this).serialize(), function(data, status){
Is it pasible to find all occurrences of strings "North" and "North-East" in some txt file and save number of occurrences in some variables?? Say I have... Code: [Select] <? echo("do something"); include("include_file.php"); echo("do something else"); ?> include_file.php Code: [Select] <? $a_$string = "a string"; echo($a_string); ?> I have put an error in the include_file.php an extra $ in the variable name. The first script would kick up an error that there is a problem with file include_file.php as line 3 or what ever the line may be. How can I have it so I can choose what the error message is, say a cryptic code and the line number without having the file names show as this is showing up my hidden includes folder and the file name which means that someone may try to visit this page alone and this can cause security issues. Adding in extra lines to every file to see if it is being use correctly a bit like sessions is not an option although I have looked at it as I have houndreds of files to alter in this case. I have just tried this instead of the top script but I does not show the secret code on error Code: [Select] <? echo("top"); @include("dummy.php") or die("secreterrorcode123"); echo("bottom"); ?> Why smarty won't find my template file?

I have the following variable: $text = "javascript:openimage('http://images.icecat.biz/img/norm/high/5966342-254.jpg',850,850)" Now I want to put the string "http://images.icecat.biz/img/norm/high/5966342-254.jpg" into a variable called $url ( $url = "http://images.icecat.biz/img/norm/high/5966342-254.jpg" ) How do I do this? hello I've some code and I want remove text between Publisher: and >. This text is not fixed. anyone can help me to find text between two char and replace them with "" using php? thank you Seems this should be easy, but I'm not finding the solution. Functions like scandir, readdir, and glob that I've been looking at all seem to need me to actually know more about my directory path than I can ahead of time. Here's what I want to do: 1. expand a .tar file (consists of directory, subdirectories, files, and is variable) that I've uploaded to the server 2. look through that expanded directory for a subdirectory named ".pn" -- (note that all my .tar files will have this folder deep in several subdirectories that will be variable in number and have different names depending on the original .tar file) 3. copy the entire contents of the .pn folder to another folder already on my server The hosting company, no doubt, has likely blocked some of the functions I'll need as well, but if someone can point me in the right direction to start, it would be greatly appreciated. Thanks! Satre This is probably an easy one, but I can't figure it out and it's pretty much not searchable. on a linux-machine i have installed filezilla the filezilla runs pretty well and all is ok. now i need to have the passwd that i have stored years ago. The passprhase is stored in a plain in a file called sitemanager.xmlfile I want to find that file and open it with a terminal command. find . -name *.sitemanagerwell i thought that this will return the file I'm looking for. Now how do I open it automatically, without typing the name? find . -name *sitemanager.xm | openThis doesn't work. It says it doesn't found the open command. question: why it does not work on opensuse? should i use any other command - eg the following: find . -name *xyz | xargs openor find . -name *sitemanager.xml | xargs openor
find . -name *.xyz -exec open {} \;
and
find . -name *.xyz -exec open {} \; .
any and all help will be greatly appreciateagain: what is wanted and needet is to find out the passphrase in the filezilla-configuration i am making a search engine to search my site and the code is going well but i don't know how to find your search within the results and put it in bold (like google does). I use a thing called http://simplehtmldom.sourceforge.net/ for getting the html of my website. Code: [Select] <?php include('simple_html_dom.php'); ?> <?php $s = $_GET["s"]; if ($s == null) echo "you have not searched for anything"; else echo "you searched for $s<hr>"; $urls[0] = 'http://url.com/'; $urls[1] = 'http://url2.com'; foreach ($urls as $url) { $html = file_get_html($url); strip_tags($html); preg_match("/<body>(.*)<\/body>/s", $html, $body); $htmls_split = split('<', $body[1]); foreach ($htmls_split as $line) { if (preg_match("/$s.*/", $line, $matches)) { echo "<p>$matches[0]"; } } } ?> This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=306874.0

Ok i have been working on this for a day+ now. here is my delema simple .ini text file. when a user makes a change (via html form) it makes the correct adjustments. problem is the newline issue 1. if i put a "\n" at the end (when using fputs) works great, except everytime they edit the file it keeps adding a new line (i.e. 10 edits there are now 10 blank lines!!!!) 2. if i leave off the "\n" it appends the next "fgets" to that lilne making a mess Code: [Select] ##-- Loop thruoght the ORIGINAL file while( ! feof($old)) { ##-- Get a line of text $aline = fgets($old); ##-- We only need to check for "=" if(strpos($aline,"=") > 0 ) { ##-- Write NEW data to tmp file fputs($tmp,$info[$i]." = ".$rslt[$i]."\n"); $i++; } ##-- No Match else { fputs($tmp,$aline."\n"); }//Checking for match }//while eof(old) what in the world is making this such a big deal. i dont remember having this issue in the past I tried opening with w+, and just w on the temp file a typical text line would be some fieldname = some value the scipt cycles through the file ignoring comments that are "#" ps the tmp file will overwrite the origianl once complete all i really want to know is WHY i cant get the newline to work, and what is the suggested fix EDIT: i just tried PHP_EOL and it still appends another newline Hi, I am writing several scripts and some are used to amend extra information to a text file. However, I added a hyperlink to the text file so that the user can go back to a page where they can add extra information. However, since I have done this every time I amend more text to the text file, the extra text appears below the hyperlink rather than above it, and I was wondering if there was a way around this. My amend code is as follows: Code: [Select] <html> <head> <title>Amend File</title> <link rel="stylesheet" type="text/css" a href="rcm/stylesheet.css"> </head> <?php if($_POST['append'] !=null) { $filename="C:/xampp/htdocs/rcm/denman2.txt"; $file=fopen($filename, "a"); $msg="<p>Updated Information: " .$_POST['append']. "</p><br>"; fputs ($file, $msg); fclose($file); } ?> <body> <h1>Do you want to append to a document?</h1> Enter Updated Information: <form action="amendfile2.php" method="post"> <input type="text" size="40" name="append"><br><br> <input type="submit" value="Add updated information to report"> </form> <form action="viewfile3.php" method="post"> <input type="submit" size="40" value="View Web Blog"> </form> <form action="loginform.php" method="post"> <input type="submit" value="Click here to go to the Log In Screen"> </form> </body></html> And my text file is as follows: Code: [Select] <h1>Accident Report</h1> <p>First Name: Andrew Last Name: Denman Age: 18 Complete Weeks Since Accident: 2<br> <a href="amendfile2.php">Amend to this file</a> Any help would be appreciated Hi I want to hide the login box's of my webpage once you login. I have thought of two ways of doing it but which one would you say is better practice? 1. use a PHP if statement to echo 'Display: none on css' - when viewing source code it still shows the form but not displayed on page itself 2. use a PHP if statement around the whole <form></form> so it physically doesnt write the html if already logged in? Or if anyone has a better way it would be appreciated if you would share it? Thanks in advance so I have this code..........(not in brackets sorry) <table width="410" border="1" cellspacing="0" cellpadding="0"> <tr> <td width="339" bgcolor="#999999" scope="col">EVENTS</td> </tr> <tr> <td class="afasd"><?php echo date("F",strtotime("-0 month")); ?></td> </tr> <tr> <td><?php if ($startdate == date("F",strtotime("-0 month"))){ echo "<p><a href='viewevent.php?eventid=$eventid'>$startdate - $enddate --- $event</a></p>\r\n"; }else{ echo"there are no events scheduled for this month" ;} ?></td> </tr> <tr> <td class="adfaf"><?php echo date("F",strtotime("+1 month")); ?></td> </tr> <tr> <td><?php if ($startdate == date("F",strtotime("+1 month"))){ echo "<p><a href='viewevent.php?eventid=$eventid'>$startdate - $enddate --- $event</a></p>\r\n"; }else{ echo"there are no events scheduled for this month" ;} ?></td> </tr> <tr> <td class="jasdfjs"><?php echo date("F",strtotime("+2 month")); ?></td> </tr> <tr> <td><?php if ($startdate == date("F",strtotime("+2 month"))){ echo "<p><a href='viewevent.php?eventid=$eventid'>$startdate - $enddate --- $event</a></p>\r\n"; }else{ echo"there are no events scheduled for this month" ;} ?></td> </tr> </table> so Only the third piece is working displaying correct things...........the other two don't display at all....... |
