使用fpdf的列文字换行

问题描述

我正在使用fpdf生成pdf文件.我想输出带有一些列的表.我遇到的问题是我无法将列标签的文本标题从第二个数组包装到第八个数组.超出数组长度的文本不在列标签的视图中.任何建议都会有很大帮助.

I am using fpdf for generating a pdf file. I wanted to output a table with some columns. The problem I encountered is I am unable to wrap the text header of column label from second to eighth array. The text exceeding the array length is not in a view of column label.Any suggestions will be great help.

这是代码

$header = array(
array("label"=>"Subject Category", "length"=>75, "align"=>"L"),
array("label"=>"Total Pubs", "length"=>15, "align"=>"L"),
array("label"=>"%Pubs in Top 10% SNIP", "length"=>15, "align"=>"L"),
array("label"=>"%Pubs in Top 25% SNIP", "length"=>15, "align"=>"L"),
array("label"=>"Total Cites", "length"=>15, "align"=>"L"),
array("label"=>"%Cites in Top 10% SNIP", "length"=>15, "align"=>"L"),
array("label"=>"%Cites in Top 25% SNIP", "length"=>15, "align"=>"L"),
array("label"=>"4-year H_Index", "length"=>15, "align"=>"L")

);

foreach ($header as $col) {
  $pdf->Cell($col['length'],15, $col['label'], 1, '0', $col['align'], true);
 }

推荐答案

我不得不在之前使用fpdf包装一些文本，最终这样做:

I had to wrap some text using fpdf before and ended up doing this:

function word_wrap(&$fpdf, $text_that_might_need_wrapping) {

    // 64 was the maximum length that worked in my instance, in your case
    // I'm guessing this would be 15
    $max_length_before_wrap = 64;

    if (strlen($text_that_might_need_wrapping) > $max_length_before_wrap) {
        // Split text into words
        $words = explode(" ", $text_that_might_need_wrapping);
        $total_words = count($words);
        $line = '';
        $word = 0;

        // Generate a new text line from those words until the new line is nearly too long
        while ($word < $total_words and strlen($line . $words[0] . " ") < $max_length_before_wrap){
            $word++;
            $line .= array_shift($words) . " ";
        }

        // Add text to PDF and a new line
        $fpdf->Cell(0,5,$line, 0, 2, 'C');
        $fpdf->Ln(2);

        // Continue to wrap the remaining text
        $rest_of_text = implode(' ', $words);
        word_wrap($fpdf, $rest_of_text);
    } else {
        $fpdf->Cell(0,5,$text_that_might_need_wrapping, 0, 2, 'C');
    }
}

以下是从 fpdf.org 复制的示例:

Here's an example copied from fpdf.org:

$fpdf = new FPDF();
$fpdf->AddPage();
$fpdf->SetFont('Arial','B',16);
$fpdf->Cell(40,10,'Hello World!');
word_wrap($fpdf, "Some really really long text that needs wrapping a lot");
$fpdf->Output();
