Method #2

In PHP, you can increment letters like numbers by first converting the letters into their corresponding ASCII values, incrementing the ASCII values, and then converting them back to letters. Here's an example:

php
$letter = 'a'; // Starting letter
$letter++;
echo $letter; // Output: b

In the above code, $letter is initially set to the letter 'a'. When $letter++ is executed, the letter is converted to its ASCII value (97), incremented by 1, and then converted back to a letter ('b').

You can use this method to increment letters in PHP just like you would with numbers.

Remove Unicode Zero Width Space PHP

✔ Recommended Answer This: $newBody = str_replace("​", "", $newBody); presumes the text is HTML entity encoded. This: $newBody = str_replace("\xE2\x80\x8C", "", $newBody); should work if the offending characters are not encoded, but matches the wrong character (0xe2808c). To match the same character as #8203; you need 0xe2808b: $newBody = str_replace("\xE2\x80\x8B", "", $newBody); Source: stackoverflow.com Answered By: Jef Method #2 To remove Unicode zero width space (ZWSP) from a string in PHP, you can use the str_replace() function to replace the ZWSP character with an empty string.

PhpStorm, return value is expected to be 'A', 'object' returned

✔ Recommended Answer Has to be because object can be ANY class instance, even B etc. You can annotate the create() method with generics PHPDoc to tell that the return type will be the same as the input parameter class string. It gives more context info to the IDE. /** * @template T * * @param string $class * @return T */ private function create(string $class) : object { return new $class(); } P.S. Instead of create('B'); better use create(B::class) . This way the IDE can track the usages of that class for refactoring/search purposes etc. Source: stackoverflow.com Answered By: LazyOne Method #2 This error message suggests that your code is expecting a value of type 'A' to be returned, but instead, the code is returning an object. This error can occur in PhpStorm, or any other PHP development environment. To resolve this error, you should check the function or method that is returning the object and ensure that it is returning

Laravel file upload returns forbidden 403, file permission is 700 not 755

✔ Recommended Answer The issue you are facing could be due to incorrect file permissions for the storage folder. Here are some steps to fix the problem: SSH into your cPanel server. Change the permission of the storage folder to 755: chmod -R 755 storage/ This command will change the permission of the storage folder and all its contents to 755, which should give the web server permission to read and write to the folder. Check the ownership of the storage folder. Ensure that the owner of the folder is the same as the user running the web server (typically www-data on Apache): ls -l This command will list the files and folders in the current directory along with their ownership and permission details. Make sure that the owner of the storage folder is the same as the user running the web server. If the ownership is incorrect, you can change it using the following command: chown -R www-data:www-data storage/ This command will change the ownership of the storage folder and all its conten
