preg_match('/Text: .+, (\d+x\d+)[^\d]/si', $input, $output);
```
Specifically: I don't understand what's being used. [^\d] after (\d+x\d+), what gives you this, as I understand, denial?

Text: .+, (\d+x\d+)[^\d]/si
```
- Text: - ordinary text with a lacuna at the end
- .+ - an inaccurate number of symbols, apart from the rupture symbol
  lines
- , - the usual lacunae comma
- \d+ - inaccurate number of figures
- x - the usual "x" symbol.
- \d+ - inaccurate number of figures
- [^\d] - any symbol other than numbers
- s search in one line (without the rupture symbol)
- i - not sensitive to the register.

You can generate the elements from PHP, with the values obtained from the database and start simulating updates with javascript using https://developer.mozilla.org/es/docs/Web/JavaScript/Referencia/Objetos_globales/Math/random // Define la variable que contendrá los input let datos; // Crea una función para actualizar const updateData = function() { // Recorre y asigna un valor al azar entre -5 y 5 datos.forEach(item => { // Obtener número entre 1 y 5 let newVal = Math.floor(Math.random() * (6 - 1) + 1); // Asignar signo al azar item.value = (Math.random() < 0.5) ? -newVal : newVal; }); // Volver a ejecutar dentro de 3 segundos (3000 milisegundos) setTimeout(updateData, 3000); } // Cargar los datos y ejecutar función cuando el DOM se haya cargado window.addEventListener('DOMContentLoaded', function() { datos = document.querySelectorAll('[id^=dato]'); updateData(); });<div> Dato 1: <input type="number" id="dato1"> </div> <div> Dato 2: <input type="number" id="dato2"> </div> <div> Dato 3: <input type="number" id="dato3"> </div> <div> Dato 4: <input type="number" id="dato4"> </div> <div> Dato 5: <input type="number" id="dato5"> </div> <div> Dato 6: <input type="number" id="dato6"> </div>

Sorry, this entry is only available in Japanese. The same way of thinking is only different in other languages.var regexp = new RegExp('data-hoge="(.*?)"'); var result = regexp.exec('li id="result_0" data-hoge="4592105095" class="s-result-item"'); alert(result[1]); Use () to extract the matched value. The value enclosed in () will enter the number of () pieces, and the result 1 in order. This time, I have only one index.It is also necessary to use the shortest match of the regular expression. (.*?) ? No,4592105095" class="s-result-itemThis is the result. This is because it matches the last "". By using ?, you can match the one that matches the shortest.

Looking at the best answer. https://stackoverflow.com/questions/406230/regular-expression-to-match-a-line-that-doesnt-contain-a-word I think you'll be able to do this:<(img)(((?!noSelect)[^>])+?)(>(.*?)<\/\\1>|[\/]?>)

For the new compiler. char *path; Not a line, but a sign for one symbol. So do the static force or use it. malloc: char *path = (char*)malloc(100);

The first thing is to clarify that the range of values of a byte is [-128, 127], so the higher positive number that can be handled with a byte is 127. This occurs because the eighth bit (the first left to right) is used to indicate the sign.The above makes it impossible to represent more than that number of characters with a single byte. For this reason in java it uses the UTF-16 format in its characters, representing each with 2 bytes (from Java 9 an optimization was introduced in the form of representing the String which allows not always to use 2 bytes per character if not necessary). To be able to represent a UTF-16 character in this way, a small algorithm is made about the character code, which we show below.An example with the A:Its code is 225 in decimal (more than 127, it must be divided), and in binary 0000-0000-1110-0001 (using 2 bytes).The first 5 bits (from left to right) are discarded because they are not necessary, leaving 000-1110-0001The first 5 bits overlap in the 110x-xxxx equis. With this we get our first byte 1100-0011, which in decimal is 195.The remaining 6 bits overlap in the 10xxxxxx equis. With this we get our second byte 1010-0001, which in decimal is 161.So the representation of the A would be [195 161].This is why reading a byte with the method System.in.read()You only read the first byte of the representation of the a, which is 195.If you want to read characters you must use a Scannerthe next way. try (Scanner scanner = new Scanner(System.in)) { String cadena = scanner.next(); System.out.println(cadena); } catch (Exception e) { e.printStackTrace(); } Notice that Scanner has a method to read only one character.With the method InputStreamReader.read() If it works for you because it returns int which has a capacity of 4 bytes, which is superior to the 2 bytes of the character you introduce.

Rx won't do anything until there's a subscriber. You need to sign up. ObservableObservable.fromCallable { var settingsResult: Settings? = null Realm.getDefaultInstance().use { realm -> val settings = realm.where(Settings::class.java).findFirst() settings?.let { settingsResult = realm.copyFromRealm(it) Log.i("MY_LOGS", "settingsResult = $settingsResult") } } settingsResult } .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe({ //успех }, { //ошибка })

That's how you do it. <script type="text/javascript"> $(document).ready(function() { $('#submit_name').bind('blur', function() { $('#submit_name-desc').removeClass('cls1').addClass('cls2'); }); $('#submit_name').bind('focus', function() { $('#submit_name-desc').removeClass('cls2').addClass('cls1'); }); }); </script> How do you rewrite this code so that, with a focus on a specific object, the script waited for a couple ms and then gave a meaning-webkit-backface-visibility: hidden; ?

First, better. \. instead of just a point. It's just a point that's any symbol, so it'll even work on it. asasdasd@asdsadaSecond, why [a-z] and why {3,} ? Can't the domain be 33.com, i.e. numbers and two symbols?Well, at the end, there's a question mark, which means lazy, and at the same time there's no end of the line. $ - That's what happens even asdf@ghj.ssssssssssssssssssssssssss, because without the end of the line {2,3}? match. ss♪ And the rest is just not prohibited. So we need to point out that this is the end of the line.Anyway, your e-mail requirements are weird.

In the line$arr[$i] = (++$i); In the right part, you first increase the index per unit, and then you make an assignment on this index. That's why you're moving on to a piece of law. $i = 0; $arr= []; while ($i<10) { $arr[$i] = $i + 1; $i++; } for ($it = 0; $it < 10; $it++) { echo $arr[$it] . "<br>"; }
