Regex String Between Underscore

I need to get the markings between the underscores, for example: Com_x0020_este_x002C__x0020_texto Com_x0020_este_x002C_ _x0020_texto Thank you!

Solution 1:

What you are looking for it preg_replace documentation can be found here: http://php.net/manual/en/function.preg-replace.php and the logic you are looking for it as follows:

PHP Version:

$string = "Com_x0020_este_x002C__x0020_texto";
 print preg_replace('/_(.*?)_/', " _$1_ ", $string);

Javascript Version:

var $string = "Com_x0020_este_x002C__x0020_texto";
alert($string.replace(/_(.*?)_/g," _$1_ "));

Result: Com _x0020_ este _x002C_ _x0020_ texto

Solution 2:

You can try this, if I understand the question correctly: /_(.*?)_/g
