PHP - Replace Text In String With Php Code.
Hi,
I am trying to take a string from a database and replace everything within {} with code... similar to how posting in a forum works. so say I have "...Lorem ipsom {gallery:1} sit imet..." it will take that string (from a DB) and replace "{gallery:1}" with "<?php gallery('1'); ?>". How can this be done? Or is there keywords I can search on to find the answer? Thank you in advance. Similar TutorialsI 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 The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.
For example:
<?php $str = 'some blob ~abc~ followed by ~def~'; $arr_orig = array( '~abc~', '~def~' ); $arr_new = array( 'value~def~', 'blah' ); echo str_replace( $arr_orig, $arr_new, $str ); ?>This will echo: some blob valueblah followed by blah But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need. I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!) Hi Guys I'm sure this is really simple for you experts but it's proving to be my nemesis! I have an array of words: eg. $words = array('Apples','Bananas','Cherries'); and would like to search a string of text for these words and create link tags around them based on a simple template, <a href="#">$word_found</a> $text = "I love eating apples and bananas but hate cherries!"; So i would like to return a string like this: $text = "I love eating <a href=#>apples</a> and <a href="#">bananas</a> but hate <a href="#">cherries!</a>"; Now, I need it to do a case insensitive search, but just wrap tags around the words it finds, leaving the case as it was found in the string. I want to avoid using a function where I have to list all the replacements like this: function replace_text($text){ $replace = array('apples' => '<a href="#">apples</a>','bananas' => '<a href="#">bananas</a>'); $text = str_ireplace(array_keys($replace), $replace, $text); return $text; } because it seems very messy and long winded. Also it's not case insensitive. It seems like there must be a way of simply searching for the words in my array and wrapping tags around the found words. Please can anyone help!? Many Thanks Dan hello again need some advice cant get it working Code: [Select] SELECT * FROM `tsue_members` WHERE memberid=0 if ($row['memberid'] == '0') { $img = "1.gif"; } echo $img; Hi - newbie to php - I need to search a string and possibly replace part of it. This is how I would do it in perl: Code: [Select] if ($homepage) { if ($homepage !~ /http/i) { $homepage = "http:\/\/" . $homepage; } } I have a homepage field in the database but sometimes people put the http in, and sometimes they leave it out. In perl I can figure it out and format accordingly but it doesn't work in PHP. I'm not sure if the first line even works in PHP. Maybe if to say something like: if $homepage is not equal to nothing. I'm not sure. Any help would be appreciated. Thanks. How can I replace the comma from a string like this: You, like this => You like this You, Derp, like this => You and Derp like this You, Derp, Derpina, like this => You, Derp and Derpina like this You, Derp, Derpina, Derpson, like this => You, Derp, Derpina and Derpison like this This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=319445.0 Hello All, I've been knocking my head against the wall for several hours trying to figure out what's going on with a simple string replace. For the most part it is working beautifully, but if a string contains a similar but not exact match it still replaces the non match. I was under the impression that str_replace always looks for an exact match. I have custom tags that are in strings of text that are structured like: [A_CUSTOM_HEADER] [A_CUSTOM_TITLE] and so on. They always start with "[A_CUSTOM" and end with a " ] ". In between the start and end can be just about anything. So my problem is if I have [A_CUSTOM] and [A_CUSTOM_TAG] in the same text str_replace seems to incorrectly replace all the [A_CUSTOM_TAG] with the [A_CUSTOM] content and the match never happens for the [A_CUSTOM_TAG] content. For example:
$content = 'Here is some text and [A_CUSTOM]. Here is more text and [A_CUSTOM_TAG]'.
$content = str_replace('[A_CUSTOM]','I have a and custom',$content);
$content = str_replace('[A_CUSTOM_TAG]','I have a, custom and tag',$content);
So running that code The [A_CUSTOM_TAG] content never gets replaced correctly, it is replaced on the first pass with the [A_CUSTOM] replacement content. I hope this make sense I'm trying to explain it the best I can. I tried using preg_replace() with \b to match the whole word but didn't get anything close to the respected results...haha I'm sure I'm missing something simple...or at least I hope I am. Thanks in advance! Edited by Twitch, 22 May 2014 - 11:52 AM. May I please ask one more question? About replacing a string only if it appears *after* a particular string?
I'm having trouble replacing all occurrences of "wheel" with "TIRE" but only when the word "wheel" is after this: (W/
Example:
From this:
A large wheel is shiny.
Big 4 wheel truck (W/ wheel)
Car with a wheel, and a small toy (w/ wheel)
Four wheelers are cool
To this:
A large wheel is shiny.
Big 4 wheel truck (W/ TIRE)
Car with a wheel, and a small toy (w/ TIRE)
Four wheelers are cool
Unfortunately, I thought this worked:
$fixed = str_ireplace('wheel','tire',substr($original_string,stripos($original_string,'(W')));
...until I realized it was *cutting off* all characters up until that first '(W/'
What can be done to make this work?
Edited by Nyla, 20 November 2014 - 09:40 PM. hey guys just a simple one...im trying to replace {$name} but i dont think ive got the right prefix in the str_replace function...if anyone could tell me where i am going wrong please $content = str_replace("{/$".$variable."}", $value, $content); {$name} I embed videos on my site. I submit the embed codes to my database using a form. The codes look like this:
<iframe width="560" height="315" src="//www.youtube.com/embed/xDIgbjDGsOM?rel=0" frameborder="0" allowfullscreen></iframe>Before I submit each code, I have to change its width and height, and I have to add this: &showinfo=0after this: ?rel=0Is there a function that will allow me to do all of that simultaneously? I know about str_ireplace(). It will let me replace ?rel=0 with ?rel=0&showinfo=0, but I don't know how to simultaneously make the other changes. It's not helping that the embed code includes quotation marks. Hello, I need help with this, I need a code that removes double occurrences of \\ only, but not if followed \n. for example Hello\\n should display Hello\ + new line Hello\\\n should display Hello + new line Hello\\ should display Hello Hello\\x should display Hellox 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 Hi! Basically, I'm making a PHP file that lists things from a file, so if the file contained; '@-Line 1-@@-Line 2-@' it would produce <li><a href="#">Line 1</a></li><li><a href="#">Line 2</a></li>, but I want it so it changes the coding for 1 of every 2 lines. So I've came up with this code: $myFile = "list.txt"; $fh = fopen($myFile, 'r'); $theData = fread($fh, 100); fclose($fh); $oldtxt = array("@-", "-@"); $newtxt = array('<li><a href="#">','</a></li>'); $newData = str_replace($oldtxt, $newtxt, $theData); $array = explode("</li>", trim($newData)); $lineno = count($array); $linenofinal = $lineno - 1; for($i=1;$i<$linenofinal;$i++){ if(($i % 2)=='0'){ } } The bit that I'm stuck on is inside the if statement. How could I get it to replace for example <li> in line $i with <li class="1in2"> Thanks in advance, Daviga404 =D I'm trying to use preg_replace but I can't get it working. function replaceContent($sContent) { $aReplaceTags = array( "'\[MENU-CARD\](.*?)\[/MENU-CARD\]'is" => '\\1', "'\[CONTACT-FORM\]'is" => "Contactform", ); return preg_replace(array_keys($aReplaceTags), array_values($aReplaceTags), $sContent); } This works great however when I change '\\1' into a function the output of '\\1' will always be 1. function replaceContent($sContent) { $aReplaceTags = array( "'\[MENU-CARD\](.*?)\[/MENU-CARD\]'is" => $this->loadMenuCard('\\1'), "'\[CONTACT-FORM\]'is" => "Contactform", ); return preg_replace(array_keys($aReplaceTags), array_values($aReplaceTags), $sContent); } Anyone knows what I am doing wrong? I have the auto suggestion script. While the user is typing, results are printed below (from the database). The results are printed with bold letters that are in the search. However, this leads to errors in capitalization. The letters are replaced by users' queries, instead of from the database. Example: Search word: PHP Results: PHPfreaks, PHP tutorials But in the database this is the records: "phpfreaks" and "php tutorials". This is a script that replaces search letters with bolded: Code: [Select] $search = clean($_POST["search"]); $fname=$row['name']; //Record from database $re_fname='<b>'.$search.'</b>'; //Replace with bold letter $final_fname = str_ireplace($search, $re_fname, $fname); How to do a script that bold letters, but as they were in the database, not from search input? The title says it all,..well as all u can see, there are many methods to accomplish this done but not before undergoing through a heavy tasking process. For instance, 1. Open the file 2. Reads the content of the file into array. 3. Find out the desire line of text that we want to replace. 4. Make that line of text as variable and assigns with the new data(that we want to replace) as its values. 5.open another file. 6.Write the whole contents to the file opened in 5. 7. Put the contents back to the file of original. Can anyone contributes a better way to get this done? Like replace/delete a specific line without affecting other characters or anything therein? Thanx. P.S reading and using str_replace to make the alteration always ends up in giving some kind of result beyond desired after the first round of code execution. Hi all, hope some can help because this is giving me more grey hairs than I allready have.
I am trying to solve the following: I'm pulling in JSON data, decoding it to a array which I write to a database. However in the array are social security numbers that I don't want to store (privacyregulations). So I need to check if a row has a social security number and if it has one I want to replace it with 'anonymized'. I have got it to work successfully on a local Xampp test environment using the following script (extract off course): //first anonymize the social security number (ssn) if exists $data = json_decode($jsondata, true);
// then fill the tables foreach($data as $row) {
$insertstatement = mysqli_query($link,"INSERT INTO $tablename (personid, type, ssn) VALUES ('".$row["personid"]."', '".$row["type"]."', '".$row["ssn"]."') ON DUPLICATE KEY UPDATE type = VALUES(type), bsn = VALUES(ssn)");
This leads to a filled table where the ssn's are filled with 'anonymized' if they exist in the array and empty if it does not exist for that row. This is exactly what I want ;-).
Personid type ssn
However, when I run the same script on a Lamp production environment (lamp stack on an Azure server) it does not work. Then the scripts results in totally ignoring the whole row that contains a ssn??
Personid type ssn Hope someone can help to get this working on my production environment as well.

Hey I have a string that looks like the following: Quote top-php-tutorials-2.html I have a script that cycles through each page. The 2 in the quote above is the page number. How can I extract the number between the - and the .html and replace it with another number? I've tried Code: [Select] substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long Any input would be appreciated Hi all just a bit like twitter i have a message system where when one recieves a mail i want there username to be like @user in blue but when sending a message the @user is in the message itself along with the actual message itsself, so i am trying to get the @ and everything after it so i can then change its color, can anyone help with this? |
