I am trying to wrap numbers inside a given string in a <span>.
$datitle = "hey hey 13";
$datitle = preg_replace('/[0-9]/', '<span class="title-number">$1</span>', $datitle);
However that returns:
hey hey <span class="title-number"></span><span class="title-number"></span>
With two empty spans, without the number inside.
What I want to get is:
hey hey <span class="title-number">13</span>
How do I use the number matched by preg_replace as a backreference?
First of all /[0-9]/ means One number from 0 to 9. This means 1 fits your regexp, 3 fits your regexp. Not 13.
Second - items which are not wrapped in a () are not stored as a result of regexp. But full regexp is stored in $0.
So proper code is:
$datitle = "hey hey 13";
$datitle = preg_replace('/([0-9]+)/', '<span class="title-number">$1</span>', $datitle);
echo $datitle; // hey hey <span class="title-number">13</span>
Or:
$datitle = "hey hey 13";
$datitle = preg_replace('/[0-9]+/', '<span class="title-number">$0</span>', $datitle);
echo $datitle; // hey hey <span class="title-number">13</span>

[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.

How do you parse and process HTML/XML in PHP?
(31 answers)
Closed 1 year ago.
I have to find a values between specific tags in HTML page through php regex. but I want if HTML page contain multiple value then do preg_match_all otherwise do nothing.
For example if preg_match find 4 values in HTML then do preg_match_all in next phase otherwise if it is preg_match find only 1 tag value then do nothing.
<td class"page">
<span class="my-tag">value1</span>
<span class="my-tag">value2</span>
<span class="my-tag">value3</span>
<span class="my-tag">value4</span>
</td>
preg_match('/<td class"page">(.*?)<\/td>/s';)
now do preg_match_all in next phase because preg_match find 4 values
preg_match_all('|\<span class="my-tag"\>(.*?)\</span\>|', $html, $string);
and if HTML contain only 1 value like this
<td class"page">
<span class="my-tag">value1</span>
</td>
So if HTML contain only 1 value then do nothing
Basically, from your preg_match, you would be getting a string back that looks like this:
Array
(
[0] => <td class="page">
<span class="my-tag">value1</span>
<span class="my-tag">value2</span>
<span class="my-tag">value3</span>
<span class="my-tag">value4</span>
</td>
[1] =>
<span class="my-tag">value1</span>
<span class="my-tag">value2</span>
<span class="my-tag">value3</span>
<span class="my-tag">value4</span>
)
With that, we can just go ahead and do the match - regardless of if it only found one match or multiple matches. (Because it's not going to hurt anything to match one item or four items, I am proposing to move the logic down in your code.) Then we can just count how many it found and store that in a variable named $count.
// CHECK TO SEE IF WE FOUND A MATCH
if (isset($matches[1])) {
// GO AHEAD AND DO THE MATCH ON THE SPANS
preg_match_all('~<span class="my-tag">(.*?)</span>~s', $string, $span_matches);
$count = count($span_matches[1]);
// IF WE FOUND MULTIPLE MATCHES, LIST THEM OUT
if ($count > 1) {
print 'COUNT IS: '.$count;
print_r($span_matches[1]);
}
// WE DID NOT MATCH ANY SPAN TAGS
elseif ($count == 0) {
print 'COUNT IS ZERO - CRAP';
}
// IF WE ONLY FOUND ONE MATCH, WE DON'T NEED TO DO ANYTHING
else {
print 'COUNT IS EXACTLY 1 - DO NOTHING';
}
}
// WE DID NOT FIND AN INITAL MATCH TO BEGIN WITH
else {
print 'WE DID NOT FIND A MATCH';
}
From there, it's just a simple if/else statement to do what you want with it.
Here is a working demo:

You can combine multiple patterns in a single regex with the pipe character in parentheses:
preg_match('/(cats?|dogs?|re.*tion)/', $string, $matches);

XPath - select text after certain node

Closed 9 years ago.
I have following string
<strong>Test: </strong> BD-F5300
I am interested in getting number BD-F5300. Number could be of any thing text,number.
Any help, how can I get it? Thanks.
You could make use of preg_replace
<?php
$str='<strong>Test: </strong> BD-F5300';
echo $str = preg_replace("~<(/)?strong>(.*?)<(/)?strong>~","", $str);
OUTPUT :
BD-F5300
do like this in JavaScript:
var src = "<strong>Test: </strong> BD-F5300";
var reg = /.*<\/.*>\s*([a-zA-Z0-9-]+)/g;
var group = reg.exec(src);
console.log(group[1]+'\r\n'); //group[1] is what you want !
If all you need is to get some content after </strong> then you can just use:
preg_match('#</strong> (.+)#', $string, $matches);
The desired match will be in $matches[1]. However, this requires that the <strong> tag and the text content you want to find are both on the same line. If there are multiples of these you want to match, you may want to use preg_match_all
If there is always a space before the beginning of the final text you want and if there are never any spaces in the actual number text you want, you can avoid regex by doing this:
$str = '<strong>Test: </strong> BD-F5300';
$solution = substr($str, strrpos($str, ' ') + 1);
var_dump($solution);

Explode a paragraph into sentences in PHP
(8 answers)
Closed 9 years ago.
I would like to add span tag for every sentence which ended with "."
like:
my string:
"I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal. The whole message of the crucifixion was simply that I did not."
O/P:
"<span id="s1">I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal.</span> <span id="s2">The whole message of the crucifixion was simply that I did not.</span>"
how it possible with php?
You could do
<?php
$string="I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal. The whole message of the crucifixion was simply that I did not.";
$output=str_replace(". ",'. </span> <span id="s2">',$string);
echo '<span id="s1">'.$output.'</span>';
?>
Edit Based on Comments
This version will make sure every new replacement gets a new span id
<?php
$string="I could not have said, ’Betrayest thou the Son of man with a kiss?’ unless I believed in betrayal. The whole message of the crucifixion was simply that I did not. Testing 123. testing again.";
$dots=substr_count($string,". ");
for($i=2;$i<=$dots+2;$i++)
{
$string=preg_replace("/\. /", ".</span> <span id =\"s$i\">" ,$string,1);
}
echo '<span id="s1">'.$string.'</span>';
?>
If you explode the sentence with ". ". I want to modify the code above.
$newText = "";
$count = 0;
foreach (explode(". ",$theText) as $part) {
if(ctype_upper($part{0}))
{
$count++;
$newText .= "<span id=\"s$count\">$part</span>";
}
}
I hope it should work for abbreviations or something.
Try this code,
You will get unique id for span tag.
<?php
$str = "I could not have said, 'Betrayest thou the Son of man with a kiss?' unless I believed in betrayal. The whole message of the crucifixion was simply that I did not.";
$exp_str = explode(". ",$str);
$sentence = "<span id=\"s1\">";
$n = 2;
foreach($exp_str as $val) {
$sentence .= $val.".</span> <span id=\"s$n\">";
$n++;
}
$n = $n-1;
$sentence = substr($sentence,0,strpos($sentence,".</span> <span id=\"s$n\">"));
echo $sentence;
?>
I'm not sure if preg_replace can do this (because of the unique IDs). Otherwise it can be manually done like this:
$newText = "";
$count = 0;
foreach (explode(".",$theText) as $part) {
$count++;
$newText .= "<span id=\"s$count\">$part</span>";
}
But what about periods mid sentence, as in abbreviations or something? You could probably replace the explode with a preg_split to get a better result. For instance only split if the char right after the period is not a letter or another period.
preg_split("/\.[^\,\w]/",$theText);
Or just ensure the next char is a whitespace.
preg_split("/\.\s/",$theText);
I search in many threads in Stackoverflow but I didn't find anything relevant for my case.
Here is the source text :
<span class="red"><span>70</span><span style="display:none">1</span><span>,89</span> € TTC<br /></span>
I want to extract 70,89 with a regular expression.
So I tried :
<span class="red"><span>([0-9]+)(<\/span><span style="display:none">1<\/span><span>)(,[0-9]+)<\/span>
which returns an array (with preg_match_all in PHP) with 3 groups :
1/ 70
2/
</span><span style="display:none">1</span><span>
3/ ,89
I would like to exclude group 2 and merge 1 & 3.
So I also tried :
<span class="red"><span>([0-9]+)(?:<\/span><span style="display:none">1<\/span><span>)(,[0-9]+)<\/span>
but it returns :
70
,89
How can I merge the two groups ?
Thanks a lot for your answers, I am going to be crazy searching for this regular expression ! :)
Have a good day !
Just match the numbers that are wrapped with a plain <span>:
$str = '<span class="red"><span>70</span><span style="display:none">1</span><span>,89</span> € TTC<br /></span>';
if (preg_match_all('#<span>([,\d]+)</span>#', $str, $matches)) {
echo join('', $matches[1]);
}
// output: 70,89
