Answer : Your query looks for .box1 li within .box2 , though these two elements are siblings. Therefore, your find() query will always return 0 . For your query to work, your HTML would need to look like this: <div class="box2">text <ul class="box1"> <li>a</li> <li>b</li> <li>c</li> </ul> </div> Without altering the structure of your HTML , you can get this to work by accessing .box1 li directly: $('.box2').addClass(function(){ return 'list' + $('.box1 li').length; }); <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <ul class="box1"> <li>a</li> <li>b</li> <li>c</li> </ul> <div class="box2">text</div> Here $(this) is referring to box2 element.Only $('.box1 li').length is what you required $('.box

Answer : This should work for you: <?php $str = "Name: MR. M.A.D KARIM"; $result = ""; $arr = array(); $pattern = '/([;:,-.\/ X])/'; $array = preg_split($pattern, $str, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY); foreach($array as $k => $v) $result .= ucwords(strtolower($v)); //$result = str_replace("Mr.", "", $result); ->If you don't want Mr. in a String echo $result; ?> Input: Name: MR. M.A.D KARIM Address: 12/A, ROOM NO-B 13 Output: Name: M.A.D Karim Address: 12/A, Room No-B 13 Use Stringy composer.json "require": { "voku/stringy": "~5.0" } PHP Stringy::create('string')->toTitleCase()

Answer : FileMerge is located at within Xcode. From the command-line: cd /Applications/Xcode.app/Contents/Applications/ open . Go into that directory once it opens: Right-click on the app Choose "Make alias" Move that alias to your Applications directory You're all set. Strange. "XCode 4.5, where is FileMerge ?" suggests: The FileMerge that is bundled with Xcode 4.5 doesn't work as a standalone application. I tried compressing it from the application bundle. I was able to expand it to show the FileMerge app on the desktop. But when I tried to run it I got an error saying it couldn't be opened. Apple's developer downloads site has every version of Xcode. You could try trashing your current version of Xcode 4.5, downloading Xcode 4.5 from the developer downloads site, and see if FileMerge is there. If not, you can download Xcode 4.4 and see if that has FileMerge. Indeed, I downloaded a fresh new install o

Example 1: Write a Program to find exponential without using pow() method # include <stdio.h> int main ( ) { int base , exp ; long long result = 1 ; printf ( "Enter a base number: " ) ; scanf ( "%d" , & base ) ; printf ( "Enter an exponent: " ) ; scanf ( "%d" , & exp ) ; while ( exp != 0 ) { result *= base ; -- exp ; } printf ( "Answer = %lld" , result ) ; return 0 ; } Example 2: power func in c The function pow ( ) is used to calculate the power raised to the base value . It takes two arguments . It returns the power raised to the base value . It is declared in “math . h” header file . Example 3: powers of 2 in cpp // If not using any extra libraries // Powers of 2. If finding 2^n int main ( ) { int ans = 1 >> n ; } // Suppose we want to find x ^ y void power ( int x , int y ) { int ans = 1 ;

Answer : I found a solution to my issue and after a request, will post it here to help others. Apologies if I missed any details, it's been a while since I worked on this solution. The first thing that is required is to install Openoffice.org on the server. I requested my hosting provider to install the open office RPM on my VPS. This can be done through WHM directly. Now that the server has the capability to handle MS Office files you are able to convert the files by executing command line instructions via PHP. To handle this, I found PyODConverter : https://github.com/mirkonasato/pyodconverter I created a directory on the server and placed the PyODConverter python file within it. I also created a plain text file above the web root (I named it "adocpdf"), with the following command line instructions in it: directory=$1 filename=$2 extension=$3 SERVICE='soffice' if [ "`ps ax|grep -v grep|grep -c $SERVICE`" -lt 1 ]; then unset DISPLAY /usr/bin/soffice

Answer : I had some problems using DavMail (mainly with the tray icon). And the calendar was not easy to use. So I've searched deeper. And I found TbSync which works well together with the EAS Provider. It works out of the box. No technical configuration no background process. I just gave my account and password and everything else was detected. Addresses and Calendars are now working like a charm. The only tips you should know with TbSync is that after installing it (as an Tools → Add-ons ) the configuration can be accessed from Tools → Synchronization Settings (TbSync) : ... or alternatively under Tools → Add-on Options → TbSync : The easiest way that I have found is to use the Davmail connector. This is a Java applet that runs in the background on your Windows 10 PC. To Thunderbird it looks like IMAP for receiving email, SMTP for sending it, and LDAP for address book queries. On the Office365 side it talks the native protocols. I've been using it for about five years

Answer : There are three ways to generate your build as per the buildType . (In your case, it's release but it can be named anything you want.) Go to Gradle Task in right panel of Android Studio and search for assembleRelease or assemble(#your_defined_buildtype) under Module Tasks Go to Build Variant in Left Panel and select the build from drop down Go to project root directory in File Explore and open cmd/terminal and run: Linux: ./gradlew assembleRelease or assemble(#your_defined_buildtype) Windows: gradlew assembleRelease or assemble(#your_defined_buildtype) If you want to do a release build (only), you can use Build > Generate Signed apk . For other build types, only the above three options are available. You can find the generated APK in your module/build directory having the build type name in it. It is possible to take any existing Android Studio gradle project and build/sign it from the command line without editing any files. This makes it very n

Answer : assuming you are using latest stable version of material 2, you can use floatLabel="never" to force label to not to float. here is live working demo this is clear in documentation https://material.angular.io/components/form-field/api <form class="search-form"> <mat-form-field class="example-full-width" appearance="standard"> <input class="toolbar-search" type="text" matInput> <mat-placeholder>Search</mat-placeholder> <mat-icon matSuffix style="font-size: 1.2em">search</mat-icon> </mat-form-field> </form> Please set the appearance of mat-form-field to standard and the placeholder will stop behaving like label. Explanation : By default the mat-label in mat-form-field floats and the appearance of mat-form-field is "legacy". That means if a mat-label is not present with the form field then placeholder will start behavin
