FPDF 中的特殊字符 PHP

Question

我有一個 web 表單，用戶可以填寫該表單，內容用 FPDF 填充 PDF 和 PHP。當用戶輸入帶有撇號的單詞時，斜線出現在 PDF 之前。

同樣，商標符號等特殊字符編碼錯誤。

FPDF 常見問題解答說使用：

$str = utf8_decode($str);

但我只是不確定如何將其應用於整個 PDF。我試圖將其視為一個 HTML 頁面，但這無濟於事。

有任何想法嗎？

Answer 1

通過執行以下操作來解決這個問題（pagesubtitle 是表單中文本字段的名稱）：

$reportSubtitle = stripslashes($_POST['pagesubtitle']);
$reportSubtitle = iconv('UTF-8', 'windows-1252', $reportSubtitle);

然后打印出來：

$pdf->Write (6, $reportSubtitle);

這將刪除撇號后面的任何不需要的斜杠，並使用 'iconv' 函數打印特殊字符，例如 ™

Answer 2

以上所有對我都不起作用，但我確實讓它起作用了。

我設法通過將每個奇怪的字符轉換為其 url 值來“以野蠻的方式”做到這一點。 然后只需解碼 url 就可以了！

function em($word) {

    $word = str_replace("@","%40",$word);
    $word = str_replace("`","%60",$word);
    $word = str_replace("¢","%A2",$word);
    $word = str_replace("£","%A3",$word);
    $word = str_replace("¥","%A5",$word);
    $word = str_replace("|","%A6",$word);
    $word = str_replace("«","%AB",$word);
    $word = str_replace("¬","%AC",$word);
    $word = str_replace("¯","%AD",$word);
    $word = str_replace("º","%B0",$word);
    $word = str_replace("±","%B1",$word);
    $word = str_replace("ª","%B2",$word);
    $word = str_replace("µ","%B5",$word);
    $word = str_replace("»","%BB",$word);
    $word = str_replace("¼","%BC",$word);
    $word = str_replace("½","%BD",$word);
    $word = str_replace("¿","%BF",$word);
    $word = str_replace("À","%C0",$word);
    $word = str_replace("Á","%C1",$word);
    $word = str_replace("Â","%C2",$word);
    $word = str_replace("Ã","%C3",$word);
    $word = str_replace("Ä","%C4",$word);
    $word = str_replace("Å","%C5",$word);
    $word = str_replace("Æ","%C6",$word);
    $word = str_replace("Ç","%C7",$word);
    $word = str_replace("È","%C8",$word);
    $word = str_replace("É","%C9",$word);
    $word = str_replace("Ê","%CA",$word);
    $word = str_replace("Ë","%CB",$word);
    $word = str_replace("Ì","%CC",$word);
    $word = str_replace("Í","%CD",$word);
    $word = str_replace("Î","%CE",$word);
    $word = str_replace("Ï","%CF",$word);
    $word = str_replace("Ð","%D0",$word);
    $word = str_replace("Ñ","%D1",$word);
    $word = str_replace("Ò","%D2",$word);
    $word = str_replace("Ó","%D3",$word);
    $word = str_replace("Ô","%D4",$word);
    $word = str_replace("Õ","%D5",$word);
    $word = str_replace("Ö","%D6",$word);
    $word = str_replace("Ø","%D8",$word);
    $word = str_replace("Ù","%D9",$word);
    $word = str_replace("Ú","%DA",$word);
    $word = str_replace("Û","%DB",$word);
    $word = str_replace("Ü","%DC",$word);
    $word = str_replace("Ý","%DD",$word);
    $word = str_replace("Þ","%DE",$word);
    $word = str_replace("ß","%DF",$word);
    $word = str_replace("à","%E0",$word);
    $word = str_replace("á","%E1",$word);
    $word = str_replace("â","%E2",$word);
    $word = str_replace("ã","%E3",$word);
    $word = str_replace("ä","%E4",$word);
    $word = str_replace("å","%E5",$word);
    $word = str_replace("æ","%E6",$word);
    $word = str_replace("ç","%E7",$word);
    $word = str_replace("è","%E8",$word);
    $word = str_replace("é","%E9",$word);
    $word = str_replace("ê","%EA",$word);
    $word = str_replace("ë","%EB",$word);
    $word = str_replace("ì","%EC",$word);
    $word = str_replace("í","%ED",$word);
    $word = str_replace("î","%EE",$word);
    $word = str_replace("ï","%EF",$word);
    $word = str_replace("ð","%F0",$word);
    $word = str_replace("ñ","%F1",$word);
    $word = str_replace("ò","%F2",$word);
    $word = str_replace("ó","%F3",$word);
    $word = str_replace("ô","%F4",$word);
    $word = str_replace("õ","%F5",$word);
    $word = str_replace("ö","%F6",$word);
    $word = str_replace("÷","%F7",$word);
    $word = str_replace("ø","%F8",$word);
    $word = str_replace("ù","%F9",$word);
    $word = str_replace("ú","%FA",$word);
    $word = str_replace("û","%FB",$word);
    $word = str_replace("ü","%FC",$word);
    $word = str_replace("ý","%FD",$word);
    $word = str_replace("þ","%FE",$word);
    $word = str_replace("ÿ","%FF",$word);
    return $word;
}

當然我調用函數

$weirdword = "Días, Miércoles, Sábado,miércoles"; //Some spanish days
$weirdword = em($weirdword);
$weirdword = urldecode($weirdword);
echo $weirdword;

給出輸出：

Días, Miércoles, Sábado,miércoles

Answer 3

以上解決方案都不適合我，所以我解決了這樣的問題：

$this->AddFont('Arial','','arial.php');
$this->SetFont('Arial','',12);
$this->Cell(0,5,iconv("UTF-8", "CP1250//TRANSLIT", $string),0,1,'L');

在嘗試以上幾行之前，請執行以下操作：

從 c:/Windows/Fonts/Arial.ttf 復制到 FPDF 的 /tutorial 文件夾。

編輯makefont.php的內容

require('../makefont/makefont.php');
MakeFont('arial.ttf','cp1250');

執行 makefont.php

將以下文件復制到 FPDF 的 /font 文件夾中： arial.php arial.ttf arial.z

最后，定義“字體文件夾”。 打開 fpdf.php（主庫文件）並添加：

define('FPDF_FONTPATH','font');

PDF適用於所有特殊字符，我相信這是FPDF最初使用的Arial字體本身的問題。 如果其他字體支持您的字符，它也應該適用於其他字體。 祝你好運！

Answer 4

以上都沒有解決我的問題。 我通過以下方式解決了它：

setlocale(LC_CTYPE, 'en_US');

$value = iconv('UTF-8', 'ASCII//TRANSLIT', $value);
$fpdf->Cell(140, 6, $value, 1);

希望你會有所幫助。

Answer 6

此類是 FPDF 的修改版本，增加了 UTF-8 支持。 此外，它僅嵌入文檔中使用的字體的必要部分，使文件大小比嵌入整個字體小得多。 這些功能最初是為 mPDF 項目開發的。

Answer 7

我用它作為$str = preg_replace('/[^A-Za-z0-9_-]/','', $str); 對我來說已經足夠了，我消除了非字母數字字符

Answer 8

為什么不使用 function PDF 推薦的？

$text = utf8_decode($text);

這個對我有用。

Answer 9

這對我來說是這樣的： iconv("UTF-8", "ISO-8859-1//TRANSLIT//IGNORE", your-text-var-here )

Answer 10

假設您的特殊字符是“°C”，您必須以這種方式對其進行編碼

> $pdf->Cell(X(int),Y(int),iconv("UTF-8", "CP1250//TRANSLIT", '°C'));

Answer 11

試試這個簡單的函數： utf8_encode($txt) 。 這個對我有用。
