PHP - Preg_replace Help - Replace ' " \ And / ?
I need a way of just replacing those three characters (",',\,/) with nothing, any ideas?
Similar TutorialsHi, bit stuck on how to find and replace "<" and ">" with "<" and ">". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once here's an example below Code: [Select] <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> the desired output would be: <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> help on this would be great Cheers Rob Hi I'm trying the following code: Code: [Select] $t = '12<-- AB_C -->'; $AB_C = 'abc'; echo preg_replace('/\<-- ([A-Z_]+) --\>/', "$$1", $t);I want to get "12abc" , but it outputs: 12$AB_C , so, it not recognize the replacement as dynamic variable. Is it any way to use the matched word in preg_replace() as a variable, or dynamic variable? 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? Hi guys I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words. $find = "left"; $replace = array("up","down","forward","backwards"); $text = "left left left left"; echo str_replace($find,$replace,$text); The Output is: array array array array Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? Thanks i get the following error in the comments in wordpress blog..: Warning: preg_replace() [function.preg-replace]: No ending delimiter '~' found in /home/doughhhh/public_html/wp-content/themes/upload/includes/theme-comments.php on line 75 the content of the file is: Code: [Select] <?php // Fist full of comments if (!function_exists("custom_comment")) { function custom_comment($comment, $args, $depth) { $GLOBALS['comment'] = $comment; ?> <li <?php comment_class(); ?>> <a name="comment-<?php comment_ID() ?>"></a> <div id="li-comment-<?php comment_ID() ?>" class="comment-container"> <div class="comment-head"> <?php if(get_comment_type() == "comment"){ ?> <div class="avatar"><?php the_commenter_avatar($args) ?></div> <?php } ?> <div class="reply"> <?php comment_reply_link(array_merge( $args, array('depth' => $depth, 'max_depth' => $args['max_depth']))) ?> </div><!-- /.reply --> </div><!-- /.comment-head --> <div class="comment-entry" id="comment-<?php comment_ID(); ?>"> <span class="arrow"></span> <div class="comment-info"> <div class="left"><span class="name"><?php the_commenter_link() ?></span></div> <div class="right"> <span class="date"><?php echo get_comment_date(get_option( 'date_format' )) ?> <?php _e('at', 'themejunkie'); ?> <?php echo get_comment_time(get_option( 'time_format' )); ?></span> <span class="perma"><a href="<?php echo get_comment_link(); ?>" title="<?php _e('Direct link to this comment', 'themejunkie'); ?>">#</a></span> <span class="edit"><?php edit_comment_link(__('Edit', 'themejunkie'), '', ''); ?></span> </div> <div class="clear"></div> </div> <?php comment_text() ?> <?php if ($comment->comment_approved == '0') { ?> <p class='unapproved'><?php _e('Your comment is awaiting moderation.', 'themejunkie'); ?></p> <?php } ?> </div><!-- /comment-entry --> </div><!-- /.comment-container --> <?php } } // PINGBACK / TRACKBACK OUTPUT if (!function_exists("list_pings")) { function list_pings($comment, $args, $depth) { $GLOBALS['comment'] = $comment; ?> <li id="comment-<?php comment_ID(); ?>"> <span class="author"><?php comment_author_link(); ?></span> - <span class="date"><?php echo get_comment_date(get_option( 'date_format' )) ?></span> <span class="pingcontent"><?php comment_text() ?></span> <?php } } if (!function_exists("the_commenter_link")) { function the_commenter_link() { $commenter = get_comment_author_link(); if ( preg_match( '~]* class=[^>]+>~', $commenter ) ) {$commenter = preg_replace( '~(]* class=[\'"]?)~', '\\1url ' , $commenter ); } else { $commenter = preg_replace( '~(<a )/', '\\1class="url "~' , $commenter );} echo $commenter ; } } if (!function_exists("the_commenter_avatar")) { function the_commenter_avatar($args) { $email = get_comment_author_email(); $avatar = str_replace( "class='avatar", "class='photo avatar", get_avatar( "$email", $args['avatar_size']) ); echo $avatar; } } ?> help! [attachment deleted by admin] preg_replace() asks that "Delimiter must not be alphanumeric or backslash" in the pattern. So I changed $new_text = preg_replace($_POST['withthis'] ,$_POST['withthis'],$_POST['text']); to this $replacethis = $_POST['replacethis']; $new_text = preg_replace("/$replacethis/",$_POST['withthis'],$_POST['text']); It works fine, but out of curiosity, is there any way to have the POST variable as a parameter directly, and why does it not work? Just to try it, I attempted: "/$_POST['withthis']/" and $_POST["/'withthis'/"] and both do not work. str_replace is a better option I think, but I am just trying to get a better understanding of this delimiter rule. Thanks for your time! So I wanted to create stickers on my forum where people type in say ":Blobby-Tired" and then instead of the comment showing ":Blobby-Tired" it shows an html image tag displaying a picture of Blobby in the comment box So I created the following page CommentUpload.php However my sql fails to insert it despite the fact when I "echo $new" it shows the image on the page correctly And it can't be my sql insert code as if I change $new variable for "$BodyText" int he SQL query it it inserts ":Blobby-Tired" OK?
<?php
include 'dbconnect.php';
session_start();
if(isset($_POST["submit"]) && !empty($_POST["CommentText"])){
$id = intval($_SESSION['id']);
echo $_SESSION['id'] . '<p> </p>' ;
$BodyText = $conn -> real_escape_string($_POST['CommentText']) ;
$User = $_SESSION['username'];
//Replace flairs with <img> tags
/*not working currently) */
$new = str_replace(":Blobby-Tired","<img src='flairs/Blobby-Tired.jpg'> </img>","'$BodyText'");
echo "$new";

Edited April 28 by Fishcakes Im dealing with html links in a database where I need to execute a small piece of php code. Well mysql doesnt execute php code thats held in a table. The easiest way for me to do this is just add the links without the code, & set up a function that will replace anything I set to for example in my case a link lookin like this: http://mysite.com/index.php?page=offers&blah=blah&sid= needs to look like this; http://mysite.com/index.php?page=offers&blah=blah&sid=<?php echo $_SESSION['login']; ?> so I would need a function like <?php $replace('sid=','sid=<?php echo $_SESSION['login'];?> ?> something like that. And I know its possible & I could create a function like this but honestly right now I am so tired after working 12 hours im lazy dont want to think to hard while I know there are a lot of people out there that have a function like this already. If you dont have one & dont feel like writing one for me could you atleast point me in the right direction so I dont have to think to hard?! Thanks!! I have a website that has definitions and articles. I need a code that craws the php content pulled from my database, finds a specified word and replaced that word with a link. For example If "car" appears replace with <a href="http://www.website.com/car.php">car</a> Thanks Todd Hi everyone!! I just started learning PHP two weeks ago and I hope someone can help me!! I need to do a find and replace on a string, and each replace needs to have an unique id, and if that unique id exists in a table then return the value on the table. Make sense? So like "find all the Xs in the string, replace with "X1, X2, X3...", then if "X3' exists on TableB, return value "X3 is on the table and has a value of Y3". I actually got this to work already but it takes a long time to do it so I'm hoping someone could give me some advice on how to make it more EFFICIENT: // PART ONE, find all "X" and replace with unique_id for ($count = 1; $count <= strlen($string); $count++) // do this loop as many times as there are characters in $string { $unique_id = "replacement_" . $count; // give each replacement an unique id (replacement_1, replacement_2, replacement_3, etc..) $string = preg_replace("X", $unique_id, $string , 1); // find X and replace it with the $unique_id in $string, and only do this ONCE } $count_replacements = substr_count($string,"replacement_"); // count how many replacements occured in total // PART TWO, find all unique_ids in tableB and echo the unique_id_value for ($count = 1; $count <= $count_replacements; $count++) // do this loop as many times as there were replacements { $unique_id = "replacement_" . $count; // set the unique_id of each replacement $show_tableB = mysqli_query($link, 'SELECT * FROM tableB'); // select the unique_ids and the unique_id_values in TableB while ($row = mysqli_fetch_array($show_tableB)) { $tableBs[] = array('unique_id' => $row['unique_id'], 'unique_id_value' => $row['unique_id_value']); } foreach($tableBs as $tableB): // for each entry in TableB, if the unique_id in TableB matches the unique_id of the replacement, return the unique_id_value if ($tableB['unique_id'] == $unique_id) { echo $unique_id . " is on TableB and it has a value of ". $tableB['unique_id_value'] } endforeach; } The problem with this is: its not very efficient. If $string has 500 charachters, it does the "PART ONE" 500 times. Then, say it found 300 Xs, it does "PART TWO" 300 more times. And every time it does "PART TWO", it checks all entries in TableB (which could be 200 or more). So, that's it. Anyone has a better idea of how to do this?? Thanks!!!! In the text, Code: [Select] It will eventually go away.Once the carriers merge, the combined airline, will operate as Southwest. It has its logo and colors. 2.3 AirTran brand will no longer be used. In the above text, how to replace "." with ". " and not in 2.3. how to add space after "." only if it has alphabets and not to replace after numeric characters. Hello, I need a php function or some type of little parser that will find if a user submit's a Code: [Select] ' then it converts it into Code: [Select] "before I grab it and submit it into my database? How would I go about getting some code to convert all the input ' to " ? Thank you, Can someone please help me with an array problem i can not figure out. I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array. 1, "mysql_field_name", "Title of form field" 2, "", "" and so on then the form will be shown based on the array. I have the following draft code which I am working with. any suggestions on how i may do this array ? Code: [Select] <?php $options = array( '1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'), '2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'), '3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'), '4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'), ); // $options = array(1 => "option1", "option2", "option3", "option4"); // the line above works but i want to include the name of the mysql field as well. $userid = 1; ?> <div style="align: center; margin: 12px; font-family:Tahoma;"> <br><br><?php if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql. $res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'"); foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); } $ok_to_update = "no"; } elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data. // error checking // foreach($options as $key => $value) { // $_POST[$i] = ""; // } $ok_to_update = "yes"; } if ($_POST['Update'] == "Update" && $ok_to_update == "yes") { // $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database. ?><p><br><br><br>Thank you for updating</p><?php } else { ?><form name="form1" method="post" action=""> <?php foreach($options as $key => $value) { ?><p><?php echo($value); ?>: <input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p> <?php } ?> <input name="Update" type="submit" value="Update"> </form> <?php } ?> </div> Hi guys I am a newbie with PHP and I have been trying to solve this problem for 3 days.. Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button.. The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears "Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27" When I check online I have this message "500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed." Are my codes wrong??? My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland Thanks for your help! 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!) cant work out this mysql syntax error "operation":"medupdate","medid":"","name":"ibo","medyear":"5","medmonth":"21","medday":"1","recuser":1,"SuccFail":"fail","SuccFailMessage":"error occured You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '''WHERE med_id=' at line 2","ResultData":""} Code: [Select] $sql="update metodology set med_description='".$req['name']."', med_year='".$req['medyear']."', med_month='".$req['medmonth']."', med_day='".$req['medday']."', med_recorddate= now(), med_recorduserid= 1'"; $sql.= " WHERE med_id=".$req['medid']; I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? Just started. I am pretty sure composer.json wasn't changed. journalctl doesn't show anything. Maybe Doctrine related, however, nothing seems to help.
Any ideas?
