I have string like <p>{{name}}</p>
and I tried below code:
$subject="<p>{{name}}</p>";
$pattern="/(\[\[|<p>{{)\w+(]]|}}</p>)/";
$success = preg_match($pattern, $subject, $match);
if ($success) {
$str = substr($match[0], 5,-2);
echo $str;
} else {
echo 'not match';
}
How can I extract name value using regex function.
No need to check p tag as you want only text inside {{...}}.If you want to get all value inside {{..}} try preg_match_all like this
<?php
$subject="<p>name is {{name}} and age is {{age}}</p>";
preg_match_all('#\{\{(.*?)\}\}#', $subject, $match);
print_r($match[1]);
?>

You will get array of values inside {{...}}
Array
(
[0] => name
[1] => age
)
If you are looking for name between a <p> tags and double opening and closing curly braces {{ }}, you could also do it like this:
Explanation
<p>{{\K(?=}}<\/p>) which asserts that what follows is }}</p>You can use preg_match_all to find all of the matches, or use preg_match to return the first match.
Your code could look like:
$subject="<p>{{name}}</p>";
$pattern="/<p>{{\K.+?(?=}}<\/p>)/";
$success = preg_match($pattern, $subject, $match);
if ($success) {
$str = substr($match[0], 5,-2);
echo $str;
} else {
echo 'not match';
}
Note that $str will be false in this case using substr.
Try using a pattern with a capture group which isolates the name you want:
subject="<p>{{name}}</p>";
$pattern="/<p>\{\{([^}]+)\}\}<\/p>/";
$success = preg_match($pattern, $subject, $match);
if ($success) {
echo $match[1];
} else {
echo 'not match';
}
You can use strip_tags and then preg_replace
$subject="<p>{{name}}</p>";
$pattern="/[^a-zA-Z]/";
$result = preg_replace($pattern, "", strip_tags($subject));
Output will be name
