How to Center Text in FPDF?
提问by NORM
How can I have this generated text appear centered in the page.
我怎样才能让这个生成的文本出现在页面的中心。
Generated = $_POSTmethod ... so I don't know how long will the text in input be. I need to have a pre-determined center parameter somehow.
Generated = $_POSTmethod ... 所以我不知道输入中的文本会有多长时间。我需要以某种方式有一个预先确定的中心参数。
Any ideas? Maybe like this:
有任何想法吗？也许是这样的：
MultiCell(0,$height,"text",0,'C') ?

Normally it's $pdf->Cell(0, $height, "text", 0, 0, 'C');but if you're doing it in a Header or Footer function it's $this->Cell(0, $height, "text", 0, 0, 'C'). Don't forget to declare $heightas a global if you're doing this in a function() call.
通常 $pdf->Cell(0, $height, "text", 0, 0, 'C');是这样，但如果您在 Header 或 Footer 函数中执行此操作，则它是$this->Cell(0, $height, "text", 0, 0, 'C'). $height如果您在 function() 调用中执行此操作，请不要忘记声明为全局变量。

Thanks taur! This works for me:
谢谢牛头！这对我有用：
$mid_x = 135; // the middle of the "PDF screen", fixed by now.
$text = $userFullName;
$pdf_file->Text($mid_x - ($pdf_file->GetStringWidth($text) / 2), 102, $text);

MultiCell(0,$height,'You can<P ALIGN="center">center a line</P>',0,'C')
回答by taur
$pdf->Text($mid_x-$pdf->GetStringWidth($text)/2,$y,$text);
