How do we move the line every 50 symbols?

jeanid

Let's say there's this variable:

$text = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.";

How do we automatically move the line so that there are not more than 50 symbols in the line?

Try it.
```
$mess = mb_substr($item['mess'], 0, 50, 'UTF-8') . '...';
```
It is still possible to try through html - to enter the div text and apply a fixed width/high for it.

On the " gonna keep" button, you're taking js to the processor, which causes a fashion window (if you use bootstrap it's "$('#id_modal')" with the password, when you press the password, you swap the password and send the form further into the controller.

Separate the line on the first found point into two parts, the results of the one:with t as ( select '#2 apps(0_-ORACLE+*.ru_ )ПРИ.13мер' Str from dual ) select regexp_replace (substr (str, 1, instr (str, '.')), '[^0-9.]+')|| regexp_replace (substr (str, instr (str, '.') + 1), '[^0-9]+' ) res from t ; Result:20.13Don't forget the cvantifiers, in this case. +♪ Function regexp_replace The default replaces all the substations found. In this case, without + The substructures will consist of separate symbols, or in other words, a cycle will be carried out for each identified symbol.

You should give a value to options like this:<select class="form-control" name="participanteEstadoCivil">  <option value="solteiro">Solteiro (a)</option> <option value="casado">Casado (a)</option> <option value="divorciado">Divorciado (a)</option> </select>

How Jonathan told you, it is good to write the problem on paper and try to make a pseudo-code to make the solution clearer.Anyway, I would probably use your place. http://php.net/manual/es/function.array-column.php foreach($array as $key => $subarray){ $vals = array_column($subarray, $key) $min = min($vals); $max = max($vals); } And so you could get the minor and the elder of each.I have not tasted the code with your array, but I feel that the index is a String ("1","2"...) perhaps trouble you.In the case of a problem with that index in String, you would have to go through each list and compare each value to the other.I hope that what I showed you will help you solve the problem of your task.

This occurs because it uses by default SQLSRV_CURSOR_FORWARD, as https://docs.microsoft.com/en-us/sql/connect/php/cursor-types-sqlsrv-driver?view=sql-server-2017 , as in the link itself indicates:sqlsrv_num_rows returns an error for result sets created with this cursor type.Translating: sqlsrv_num_rows returns an error for the defined result for results sets created with this type of cursor (referring to SQLSRV_CURSOR_FORWARD)This should be defined in sql_query, and the following parameters are supported for Scrollable which must be configured in the third parameter, the $options, as below:sqlsrv_query ($conn, $sql, array $params, array $options) The options for Scrollable are:SQLSRV_CURSOR_FORWARD (standard)Allows you to move one line at a time, starting from the first line of the result set, until you reach the end of the result set.SQLSRV_CURSOR_STATICAllows you to access lines in any order, but will not reflect changes in the database.SQLSRV_CURSOR_DYNAMICAllows you to access lines in any order and reflect changes in the database.SQLSRV_CURSOR_KEYSETAllows you to access lines in any order. However, a key set cursor does not update the row count if a row is deleted from the table (an excluded line is returned without values).SQLSRV_CURSOR_CLIENT_BUFFERED, he is not informed php.net ( http://php.net/manual/en/function.sqlsrv-query.php ), but as the proprio php.net indicates the Microsoft website then I think it works in all current versions (so I will detail)Allows you to access lines in any order. Creates a client-side cursor query (customer address in case it refers to PHP, i.e. PHP is a client of the bank server, there does not have to be with front-end, html and css, the process is in PHP itself, the other cursors different from this stand on the bank side)Whenever possible, look at the documentation, there are sessions for examples of almost all APIs, such as this http://php.net/manual/en/function.sqlsrv-num-rows.php#example-2656 In your case it must be something like:$params = array(); $options = array( 'Scrollable' => SQLSRV_CURSOR_KEYSET ); $stmt = sqlsrv_query($conn, $sql, $params, $options); $row_count = sqlsrv_num_rows($stmt); if ($row_count > 0 ){ $_SESSION['codMont'] = $var1; header('location:homee.php'); }else{ unset ($_SESSION['codMont']); $mensagem = "<div class='alert alert-danger'>Código do Montador ou senha incorretos. Tente novamente!</div>"; printf ($mensagem); printf ($var1); } Note: sqlsrv_num_rows can return 0 or FALSE, that is will depend on your need, in case FALSE is when something fails, and 0 (zero) occurs when finding zero records, then in your specific case check if it is greater than zero > 0 will work for both zero and false, but in other cases this may not be ideal, even more if you need to know what may have happened, for example:if ($row_count === false) { echo 'Erro ao obter o total'; } else { echo "Foram encontrados $row_count resultado(s)"; }

I can certainly recommend regular expressions, but regular expressions in the C++ are such a terrible API %.#include <iostream> #include <string> #include <regex> #include <cmath> int main() { std::regex regex( "tg" "\s*" "\(" "\s*" // match "tg" "(" "([-+0-9.eE]+)" // match a number ); std::string text = "bla-bla tg ( 10 ) bla-bla tg(1.2e+1)"; for (std::sregex_iterator it(text.begin(), text.end(), regex), end; it != end; ++it) { auto x = std::stod((*it)[1].str()); std::cout << "tg(" << x << ") = " << std::tan(x) << '\n'; } }

You. Memo1.Lines.Count=2 (this is if you didn't delete the default text), change. Memo1.Lines[2] and so on, it doesn't work. Forprocedure TMemoStrings.Put(Index: Integer; const S: string); var SelStart: Integer; begin SelStart := SendMessage(Memo.Handle, EM_LINEINDEX, Index, 0); if SelStart >= 0 then begin SendMessage(Memo.Handle, EM_SETSEL, SelStart, SelStart + SendMessage(Memo.Handle, EM_LINELENGTH, SelStart, 0)); SendMessage(Memo.Handle, EM_REPLACESEL, 0, Longint(PChar(S))); end; end; There's SelStart=-1, and the code's no longer in place.It's right to work with TMemo really through Clear and Add. Through the index, there's not a good exception, or StringList would get a index out of bounds.

For each folder User(User1, user2 etc) create a configuration file that says $secret_key - a unique key for each directory, and in the name of the file, add this key. $secret_key = 'dhJYmnk87asd'; config_dhJYmnk87asd.php) In any of the files launched at the user directory, the configuration file will be initially injected, after which it shall be checked. $secret_key♪ It appears that the user, without knowing the key of the other user, will not be able to connect the other user configuration or pass the key check.You should think about Unlink. But as an option for all user files to add $secret_key♪ Access or removal can only be obtained through a long selection. But in that case, the multiple challenges test and the user account can be blocked.
