Using Unicode with TCPDF

✔ Recommended Answer

You need to set the $unicode parameter on the TCPDF constructor to false and the $encoding parameter to 'ISO-639-2'(Wiki says)

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, false, 'ISO-639-2', false);

or if the above doesn't work and if you got the malayalam font, set it this way.

$fontname = $pdf->addTTFfont('/path-to-font/malayalam.ttf', 'TrueTypeUnicode', '', 32);

TCPDF, a popular PHP library for generating PDF documents, supports Unicode characters out of the box. To use Unicode with TCPDF, you'll need to make sure that your fonts and character encoding are set up correctly.

Here are the steps to follow:

  1. Set the font: TCPDF includes a set of built-in fonts that support Unicode characters. You can also use custom fonts if you need to. To set the font, call the SetFont() method and pass in the font name, the font style, and the font size. For example:

    php
    $pdf->SetFont('dejavusans', '', 12);

    This will set the font to DejaVu Sans, which includes support for many Unicode characters.

  2. Set the character encoding: To make sure that TCPDF can correctly interpret your Unicode characters, you need to set the character encoding. This should match the encoding of the text that you're working with. For example, if you're working with UTF-8 encoded text, you should set the encoding to UTF-8 by calling the setHeaderData() method and passing in the encoding parameter. For example:

    php
    $pdf->setHeaderData('', '', 'My PDF Title', 'My PDF Subject', array(0,0,0), array(255,255,255));
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$pdf->setPrintFooter(false);
$pdf->setPrintHeader(false);
$pdf->SetMargins(20, 20, 20);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
$pdf->setFontSubsetting(true);
$pdf->SetFont('dejavusans', '', 12);
$pdf->AddPage();
$pdf->Write(0, 'Hello World', '', 0, 'C', true, 0, false, false, 0);
$pdf->Output('example.pdf', 'I');

    This will set the character encoding to UTF-8.

  3. Use Unicode characters: Finally, you can use Unicode characters in your PDF document just like any other characters. For example:

    php
    $pdf->Write(0, '您好世界', '', 0, 'C', true, 0, false, false, 0);

    This will write the Chinese characters "您好世界" to the PDF document.

By following these steps, you can use Unicode characters with TCPDF to generate PDF documents that support a wide range of languages and scripts.

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. Here's an example: php $str = "Hello​ World" ; // Contains ZWSP after "Hello" // Replace ZWSP with an empty string $str = str_replace ( "\u{200B}" , "" , $str ); echo $str ; // Outputs "Hello World" without ZWSP In this example, the str_replace() functi

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
