FPDF中的特殊字符与PHP

Question

FPDF中的特殊字符与PHP

39

我有一个Web表单，用户可以填写，该内容填入FPDF和PHP生成的PDF中。当用户输入带撇号的单词时，PDF上会显示斜杠。

同样地，特殊字符如商标符号也被编码错误。

FPDF的常见问题解答建议使用：

$str = utf8_decode($str);

但我不确定如何将其应用于整个PDF文档。我试图将其视为HTML页面，但这并没有帮助。

有什么想法吗？

以上所有方法都没有对我起作用，但我最终还是解决了问题。

我采取了"野蛮人方式"，将每个奇怪字符转换为其url值，然后简单地解码url就好了！

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;
}

当然也包括我调用该函数

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

输出结果：

Days, Wednesday, Saturday, Wednesday

你可以将数组作为参数传递给 str_replace 函数。 - user1544337

我意识到这是一个巨大的hack，但最好在您的em函数结束时至少return urldecode（$word）;，这样可能会更清晰。无论如何，在没有其他方法可行时，这个方法起作用了，所以非常感谢！ :) - John

很酷，它能工作 :).. 在em函数中返回urldecode($word)可能会有用 :).. 非常感谢！ - Andrei Todorut

以上的解决方案都对我没用，所以我用以下方法解决了这个问题：

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

在尝试上述行动之前，请执行以下操作:

从c:/Windows/Fonts/Arial.ttf复制到FPDF的/tutorial文件夹。

编辑makefont.php的内容。

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

执行makefont.php 将以下文件复制到FPDF的/字体文件夹中： arial.php arial.ttf arial.z

最后，定义"字体文件夹"。打开fpdf.php（主库文件）并添加：

define('FPDF_FONTPATH','font');

PDF文件对于我来说可以使用所有特殊字符，我认为这是Arial字体本身的问题，FPDF最初就使用它。如果其他字体支持您的字符，它也应该能够正常工作。祝好运！

我知道这已经很老了，但仍然非常感谢！这似乎是解决这个问题的正确方法。我还在使用cp1250为FPDF创建（或转换）一个ttf字体，现在每个字符都能正确显示。太好了！ - beeef

以上方法都没有解决我的问题，我通过以下方式解决了它：

setlocale(LC_CTYPE, 'en_US');

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

希望你能够提供帮助。

非常好，这正是我花了3个小时寻找的东西。 - Vipul Hadiya

这是我做到的： iconv("UTF-8", "ISO-8859-1//TRANSLIT//IGNORE", 你的文本变量)

$content = urlencode($content);

将$content进行URL编码。

$content = urldecode($pdf->em_jaz($content));

将$content进行URL解码，使用$pdf对象的em_jaz方法。

这个类是FPDF的修改版，增加了UTF-8支持。此外，它只嵌入文档中使用的字体的必要部分，使文件大小比整个字体都嵌入时要小得多。这些功能最初是为mPDF项目开发的。

为什么不使用PDF建议的函数？

$text = utf8_decode($text);

这对我有效。

我曾使用过 $str = preg_replace('/[^A-Za-z0-9_-]/','', $str);，这对我来说已经足够了，它可以消除非字母数字字符。

假设您的特殊字符是“°C”，那么您必须以这种方式对其进行编码。

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

通过以下方式解决了这个问题（pagesubtitle是表单中文本字段的名称）：

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

然后将其打印出来：

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

这将删除在撇号后面的任何不必要的斜杠，并使用“iconv”函数打印特殊字符，例如™。
