I'm creating an email template and try to solve an unknown problem that add a random number of at the beginning of my tables.
So my preg_replace is:
preg_replace('/<br>(.*?)<table/s', "<br><table", $message)
I tried it on these websites and it worked:
preg_replace.onlinephpfunctions.com/
fr.functions-online.com/preg_replace.html
But on my server, it doesn't work, I also tried a preg_match_all but it doesn't work too.
Here's the source code where I use it:

I have this code:
$success = preg_match('/(.+(駅前)?駅) (\(([^線]+線)\) )?((([^線 ]+) )?(\d+[分時])?)/u', $m, $matches);
Example input text is
大正駅 (JR大阪環状線) ﾊﾞｽ 20分
This regex works on https://regex101.com/ and the code works on http://sandbox.onlinephpfunctions.com/. However, when I run the PHP code on my own computer, it never gives me a match. $matches is an empty array, and $success is 0. Yes, the exact same code. I have verified that the regex is correct (using first link) and that the code itself works (using second link). However, it still refuses to work on my own PC.
OS is Arch Linux, running PHP 7.3.11, system locale is ja_JP.UTF-8 (which I don't think matters, but just in case)
Does anyone see anything wrong with the code?
So I was able to find the problem.
First, I tried just the one-liner commented by Nick (3v4l.org/o4ADM) on my PC, and it works. (Of course it should. PHP can't be broken.)
So I figured out that it's the data I'm feeding preg_match that should be broken.
Normal prints and echos were in vain--$m is always how it should be. Then I considered AD7six's comment,
Check that the bytes for 駅 etc. are actually the same
so I looked carefully to check that the characters are all Japanese and no Chinese variants are there. And it's all Japanese, it's fine.
So what could it be?
I tried using PHP's file_put_contents to dump the variable to a file, and then typing the same text with my Japanese keyboard manually and saving them to another file. I opened Meld (a diff tool) and compared the two text and voila--the spaces on the text use a different codepoint than the usual half-width space (0x20). It uses 0xA0 instead, which is a "no-break space", apparently. What the heck.
Fortunately, a simple $m = str_replace("\u{00A0}", " ", $m) did the trick.
Thanks to everyone for leading me to the right answer!
I have to replace the following in my PHP code:
assert('is_array($myArray)');
assert('my_function_call($myVariable)');
to make it read like:
assert(is_array($myArray));
assert(my_function_call($myVariable));
The problem is that it occurs a lot of time in my code files, and I would have to open each and make the change.
I use NetBeans which has a find and replace functionality which uses regex. What regex to use for this?
Use find replace regex term:
assert\(\'is_array\($myArray\)\'\);
assert\(\'my_function_call\($myVariable\)\'\);
Escaping the regex characters fixes simple text terms.
I have a website that has been infected with malware code, heres an example:
<?php if(!isset($GLOBALS["\x61\156\x75\156\x61"])) { $ua=strto...algiyujsz-1; ?>
It's a rather large code, however I'm guessing due to some characters str_replace is not working, how would I go about replacing a string like the above via preg_replace(the ... being a wildcard)? I'm rather bad at regex and can't get it working. Or is there some way to get this working via str_replace so I have a point of reference for furure?

Solved my issue with '/<\?php if\(!isset\(\$GL(.+?)z-1; \?>/is' and preg_replace
I am currently working on a replacement tool that will dynamically replace certain strings (including html) in a website using a smarty outputfilter.
For the replacement to take place, I am using PHP's str_ireplace method, which reads the code that is supposed to be replaced and the replacement code from a database, and then pass the result to the smarty output (using an output filter), in a similar way as the below.
$tpl_source = str_ireplace($replacements['sourceHTML'], $replacements['replacementHTML'], $tpl_source);
The problem is, that although it works great on my dev server, once uploaded to the live server replacements occasionally fail. The same replacements work just fine on my dev version though. After some examinations and googling there was not much I could find out regarding this issue. So my question is, what could influence str_replace's behavour?
Thanks
Edit with replacement example:
$htmlsource = file_get_contents('somefile.html');
$newstr = str_replace('Some text', 'sometext', $htmlsource); // the text to be replaced does exist in the html source
fails to replace. After some checking, it looks like the combination of "> creates a problem. But just the combination of it. If I try to change only (") it works, if I try to change only (>) it works.
It might be that special chars like umlauts do not display on the live server correctly and so str_replace() would fail, if there are specialchars inside the string you want to replace.
Is the input string identical on both systems? Have you verified this? Are you sure?
Things to check:
Are the HTML attributes in the same order?
Are the attribute values using the same kind quote marks? (eg <a href='#'> vs <a href="#">)
Is there any other stray HTML code getting in there?
Is the entity encoding the same? (eg vs - same character; different HTML)
Is the character-set the same? (eg utf-8 vs ISO 8859-1: Accented characters will be encoded differently)
Any of these things will affect the result and produce the failures you're describing.
This was a trikcy problem, and it ended up having nothing to do with the str_replace method itself;
We are using smarty as a tamplating system. The str_replace method was used by a smarty ouput filter in order to change the html in some ocassions, just before it was delivered to the user.
Here is the Smarty outputfilter Code:
function smarty_outputfilter_replace($tpl_source, &$smarty)
{
$replacements = Content::getReplacementsForPage();
if (is_array($replacements))
{
foreach ($replacements as $replacementData)
{
$tpl_source = str_replace($replacementData['sourcecode'], $replacementData['replacementcode'], $tpl_source);
}
}
return ($tpl_source);
}
So this code failed now and then for now apparent reason... until I realized that the HTML code in the smarty template was being manipulated by an Apache filter.
This resulted into the source code in the browser (which we were using as the code to be replaced by something else) not being identical to the template code (which smarty was trying to modify). Result? str_replace failed :)
I'm trying to scrape a price from a web page using PHP and Regexes. The price will be in the format £123.12 or $123.12 (i.e., pounds or dollars).
I'm loading up the contents using libcurl. The output of which is then going into preg_match_all. So it looks a bit like this:
$contents = curl_exec($curl);
preg_match_all('/(?:\$|£)[0-9]+(?:\.[0-9]{2})?/', $contents, $matches);
So far so simple. The problem is, PHP isn't matching anything at all - even when there are prices on the page. I've narrowed it down to there being a problem with the '£' character - PHP doesn't seem to like it.
I think this might be a charset issue. But whatever I do, I can't seem to get PHP to match it! Anyone have any ideas?
(Edit: I should note if I try using the Regex Test Tool using the same regex and page content, it works fine)
Have you try to use \ in front of £
preg_match_all('/(\$|\£)[0-9]+(\.[0-9]{2})/', $contents, $matches);
I have try this expression with .Net with \£ and it works. I just edited it and removed some ":".
(source: clip2net.com)
Read my comment about the possibility of Curl giving you bad encoding (comment of this post).
maybe pound has it's html entity replacement? i think you should try your regexp with some sort of couching program (i.e. match it against fixed text locally).
i'd change my regexp like this: '/(?:\$|£)\d+(?:\.\d{2})?/'
This should work for simple values.
'#(?:\$|\£|\€)(\d+(?:\.\d+)?)#'
This will not work with thousand separator like 234,343 and 34,454.45.
