FPDF将文本左对齐，居中和右对齐 [英] FPDF align text LEFT, Center and Right

问题描述

我有三个单元格，我正在尝试将文本对齐到左"，中"和右".

I've have three cells and i'am trying to align the text to Left, Center and Right.

function Footer() 
{ 
    $this->SetY( -15 ); 


    $this->SetFont( 'Arial', '', 10 ); 

    $this->Cell(0,10,'Left text',0,0,'L');

    $this->Cell(0,10,'Center text:',0,0,'C');

    $this->Cell( 0, 10, 'Right text', 0, 0, 'R' ); 
} 

当我输出我的PDF文件时，center text会自动正确对齐. 看起来是这样:

When I ouput my PDF file, center text get automatically aligned right. This is how it looks:

有人可以告诉我我在这里做错了什么以及如何解决这个问题?

Can somebody tell me what I'm doing wrong here and how I can fix this issue?

推荐答案

如果将Cell方法的ln-parameter设置为0，则将Cell调用后的新位置设置为每个单元格的右侧.在最后2个单元格调用之前重置x坐标:

The new position after a Cell call will be set to the right of each cell if you set the ln-parameter of the Cell method to 0. You have to reset the x-coordinate before the last 2 Cell calls:

class Pdf extends FPDF {
    ...

    function Footer() 
    { 
        $this->SetY( -15 ); 

        $this->SetFont( 'Arial', '', 10 ); 

        $this->Cell(0,10,'Left text',0,0,'L');
        $this->SetX($this->lMargin);
        $this->Cell(0,10,'Center text:',0,0,'C');
        $this->SetX($this->lMargin);
        $this->Cell( 0, 10, 'Right text', 0, 0, 'R' ); 
    } 
}
