PHP - Moved: Replace All Between A String - Maybe Use Wildcards??

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, $str ); ?>This will echo: some blob valueblah followed by blah But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need. I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!) Hi - newbie to php - I need to search a string and possibly replace part of it. This is how I would do it in perl: Code: [Select] if ($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 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, 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. 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 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 hi i am about to start building a small search where users type in what they are searching for but i am wanting to also find similar things to what they have typed in. $data = mysql_query("SELECT * FROM users WHERE users.bizname='%$bizname%' "); would i use something like that.. i haven't tried yet. thought id ask first 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. This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=326004.0 Okay, I have a problem. I need to display multilple output of a file with a similar file name I.E. file1: 6002010.pdf file2: 6002010.mmddyyyy.pdf Now the first part of the file stays the same, but there is a time stamp on modified versions of the file. But in my output I need to display all the files with the 6002010. Could I use a wildcard such as 6002010* to get all the files to output on the screen? Or do I need to use a regular expression?
