Extract whatever is in brackets using regular expressions

由 不问归期 提交于 2019-12-08 05:40:25
问题 I really don't understand regex at all, and it hurts my head. I've a bit of text which looks like this blah blah blah (here is the bit I'd like to extract) ...and I don't really understand how to extract this using PHP's preg_split, or equivalent, command. How do I do this? And where's a good place to understand how preg works? 回答1: Something like this should do the trick, to match what is between ( and ) : $str = "blah blah blah (here is the bit I'd like to extract)"; if (preg_match('/\(([^\

问题 The code below has been taken directly from PHP: preg_split - Manual Example #1 preg_split() example : Get the parts of a search string <?php // split the phrase by any number of commas or space characters, // which include " ", \r, \t, \n and \f $keywords = preg_split("/[\s,]+/", "hypertext language, programming"); print_r($keywords); ?> The above example will output: Array ( [0] => hypertext [1] => language [2] => programming ) I am creating a tagging system which will allow people to type

How can I adapt my regex to allow for escaped quotes?

问题 Introduction First my general issue is that I want to string replace question marks in a string, but only when they are not quoted. So I found a similar answer on SO (link) and began testing out the code. Unfortunately, of course, the code does not take into account escaped quotes. For example: $string = 'hello="is it me your are looking for\\"?" AND test=?'; I have adapted a regular expression and code from that answer to the question: How to replace words outside double and single quotes,

PHP add quotes to array for json_decode

问题 I'm looking to json_decode a string, but running into a problem with the array elements not having quotes. JSON {"Status":"DISPUTED","GUID":[]} {"Status":"CONFIRMED","GUID":[G018712, G017623]} PHP $json = '{"Status":"CONFIRMED","GUID":[G018712,G017623]}'; $a = json_decode($json, true); print $a['Status']; Results The php print above won't display anything because there are letters mixed in with the numerics within the array and the json_decode doesn't like it. How would you add strings to

PHP preg_split with two delimiters unless a delimiter is within quotes

由 不打扰是莪最后的温柔 提交于 2019-12-06 00:28:26
Further on from my previous question about preg_split which was answers super fast, thanks to nick; I would really like to extend the scenario to no split the string when a delimiter is within quotes. For example: If I have the string foo = bar AND bar=foo OR foobar="foo bar" , I'd wish to split the sting on every space or = character but include the = character in the returned array (which works great currently), but I don't want to split the string either of the delimiters are within quotes. I've got this so far: <!doctype html> <?php $string = 'foo = bar AND bar=foo'; $array = preg_split('/
