I'm trying to get the 2010 part out of the false-2010.
i want it to echo 2010 only..
Thanks for the help.
this was what i started with and got stuck
<?php
$get2010 = preg_match('/\<!--(.*?)-->/', $get2010, $m);
echo $m[1];
?>
and oh.. the 2010 is a randomly generated number... it changes.
preg_match('!Vertical1_437\s*=\s*"\D+(\d+)"!', $get2010, $m);
echo $m[1];
This assumes it's always the RHS of Vertical1_437. I am also assuming you have that block of HTML code as a string in $get2010.
It may be helpful if you could be more specific about what data is dynamic and what is static. If Vertical1_437 and false are static and the 2010 part is the only dynamic part, then this should work:
preg_match{'#(.*Vertical1_437.*false-)(\d{1,4})(.*)#', $get2010, $m);
echo $m[2];
Mine assumes that "2010" is a digit that is 1-4 digits, you can adjust that in the {1,4} part.
This should do it for the given example. If some of that other text is dynamically generated, then There will probably be something to change.

[PHP]I have a variable for storing strings (a BIIGGG page source code as string), I want to echo only interesting strings (that I need to extract to use in a project, dozens of them), and they are inside the quotation marks of the tag
but I just want to capture the values that start with the letter: N (news)
[<a href="/news7044449/exclusive_news_sunday_"]
<a href="/n[ews7044449/exclusive_news_sunday_]"
that is, I think you will have to work with match using: [a href="/n]
how to do that to define that the echo will delete all the texts of the variable, showing only:
note that there are other hrefs tags with values that start with other letters, such as the letter 'P' : href="/profiles... (This does not interest me.)
$string = '</div><span class="news-hd-mark">HD</span></div><p>exclusive_news_sunday_</p><p class="metadata"><span class="bg">Czech AV<span class="mobile-hide"> - 5.4M Views</span>
- <span class="duration">7 min</span></span></p></div><script>xv.thumbs.preparenews(7044449);</script>
<div id="news_31720715" class="thumb-block "><div class="thumb-inside"><div class="thumb"><a href="/news31720715/my_sister_running_every_single_morning"><img src="https://static-hw.xnewss.com/img/lightbox/lightbox-blank.gif"';
I imagine something like this:
$removes_everything_except_values_from_the_href_tag_starting_with_the_letter_n = ('/something regex expresion I think /' or preg_match, substring?);
echo $string = str_replace($removes_everything_except_values_from_the_href_tag_starting_with_the_letter_n,'',$string);
expected output: /news7044449/exclusive_news_sunday_
NOTE: it is not essential to be through a variable, it can be from a .txt file the place where the extracts will be extracted, and not necessarily a variable.
thanks.
I believe this will help her.

To get just the links out of the $results array from Valdeir's answer:
foreach ($results as $r) {
echo $r;
// alt: to display them with an HTML break tag after each one
echo $r."<br>\n";
}
I'm trying to use a regex to find and replace all URLs in a forum system. This works but it also selects anything that is within bbcode. This shouldn't be happening.
My code is as follows:
<?php
function make_links_clickable($text){
return preg_replace('!(([^=](f|ht)tp(s)?://)[-a-zA-Zа-яА-Я()0-9#:%_+.~#?&;//=]+)!i', '$1', $text);
}
//$text = "https://www.mcgamerzone.com<br>http://www.mcgamerzone.com/help/support<br>Just text<br>http://www.google.com/<br><b>More text</b>";
$text = "#Theareak We know this and [b][url=https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks]here[/url] [/b]is an explanation, we are trying to fix this asap! https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks aaa";
echo "<b>Unparsed text:</b><br>";
echo $text;
echo "<br><br>";
echo "<b>Parsed text:</b><br>";
echo make_links_clickable($text);
?>
All urls that occur in bb-code are following up on a = character, meaning that I don't want anything that starts with = to be selected.
I basically have that working but this results in selecting 1 extra character in in front of the string that should be selected.
I'm not very familiar with regex. The final output of my code is this:
<b>Unparsed text:</b><br>
#Theareak We know this and [b][url=https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks]here[/url] [/b]is an explanation, we are trying to fix this asap! https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks aaa<br>
<br>
<b>Parsed text:</b><br>
#Theareak We know this and [b][url=https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks]here[/url] [/b]is an explanation, we are trying to fix this asap! https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks aaa
You can match and skip [url=...] like this:
\[url=[^\]]*](*SKIP)(?!)|(((f|ht)tps?://)[-a-zA-Zа-яёЁА-Я()0-9#:%_+.\~#?&;/=]+)
See regex demo
That way, you will only match the URLs outside the [url=...] tag.
IDEONE demo:
function make_links_clickable($text){
return preg_replace('~\[url=[^\]]*](*SKIP)(?!)|(((f|ht)tps?://)[-a-zA-Zа-яёЁА-Я()0-9#:%_+.\~#?&;/=]+)~iu', '$1', $text);
}
$text = "#Theareak We know this and [b][url=https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks]here[/url] [/b]is an explanation, we are trying to fix this asap! https://www.mcgamerzone.com/news/67/False-positive-proxy-bans-and-bot-attacks aaa";
echo "<b>Parsed text:</b><br>";
echo make_links_clickable($text);
You can use a negative lookbehind (?<!=) instead of your negated class. It asserts that what is going to be matched isn't preceded by something.
Example
If I had a string of text e.g:
<p>Hello world here is the latest news ##news?123## or click here to read more</p>
I want to look through the string and find anything starting with ##news? Then I want to save that and the id 123 and trailing hashes as a variable, so the final output would be:
$myvar == "##news?123##"
How can I use PHP to read that input string and save that specific part as a variable?
preg_match is your friend for this sort of problem.
$str='<p>Hello world here is the latest news ##news?123## or click here to read more';
$pttn='#(##news\?(\d+)##)#';
preg_match( $pttn, $str, $matches );
$myvar=$matches[0];
$id=$matches[2];
echo $myvar.' '.$id;
Assuming you're not trying to parse HTML but as you say, just find any occurrence starting with "##news?" then you can use regex happily here:
$string = '<p>Hello world here is the latest news ##news?123## or click here to read more';
$matches = array();
preg_match_all("/(##news\?.*?)\s/",$string,$matches);
print_r($matches);
i want get all/farsi_persian/*/subtitle-*.aspx from one html page
i try some regular expression on PHP but not find
can help me ?>
<span class="r0" title="Rating 0 out of 10">Farsi/Persian</span> Arrow - Third Season subtitle<br><small> Arrow.S03E03.HDTV.480p.x264-LOL </small>
Try
/farsi_persian/[^/]+/subtitle-[^.]+.aspx
try using preg_match_all(), this might work::
preg_match_all('/\/farsi_persian\/[\w-]+\/subtitle-[\d]+.aspx/', $str, $matches);
assuming there's always numbers after subtitle-
$myPattern = "/farsi_persian/[^/]+/subtitle-[^.]+.aspx";
preg_match_all($myPattern,$myText,$match);
var_dump($match);
it show null;
its worked
$myPattern = "/farsi_persian\/(.*.)\/subtitle-\d*.aspx/";
I parse an html page into a plain text in order to find and get a numeric value.
In the whole html mess, I need to find a string like this one:
C) Debiti33.197.431,90I - Di finanziamento
I need the number 33.197.431,90 (where this number is going to change on every html parsing request.
Is there any regex to achieve this? For example:
STARTS WITH 'C) Debiti' ENDS WITH 'I - Di finanziamento' GETS the middle string that can be whatever.
Whenever I try, I get empty results...don't know that much about regex.
Can you please help me?
Thank you very much.
You could try the below regex,
^C\) Debiti\K.*?(?=I - Di finanziamento$)
DEMO
PHP code would be,
<?php
$mystring = "C) Debiti33.197.431,90I - Di finanziamento";
$regex = '~^C\) Debiti\K.*?(?=I - Di finanziamento$)~';
if (preg_match($regex, $mystring, $m)) {
$yourmatch = $m[0];
echo $yourmatch;
}
?> //=> 33.197.431,90
This should work. Read section Want to Be Lazy? Think Twice.
(?<=\bC\) Debiti)[\d.,]+(?=I - Di finanziamento\b)
Here is demo
sample code:
$re = "/(?<=\\bC\\) Debiti)[\\d.,]+(?=I - Di finanziamento\\b)/i";
$str = "C) Debiti33.197.431,90I - Di finanziamento";
preg_match($re, $str, $matches);
