FPDF: Change text color while inside a Cell?

Question

I want it so that the text saying white will use SetTextColor as white, and the orange to use orange.

$pdf->SetTextColor(255,255,255);
$pdf->Cell(50,0,'WHITE ORANGE ORANGE WHITE',0,1,'C');

How do I affect the 'ORANGE' words to use an orange text color?

Answer 1

It is possible with a little trick. I just made it printing 2 Cells, one over the other, like this:

//Setting the text color to black
$pdf->SetTextColor(0,0,0);

//Printing my cell      
$pdf->SetFont('Arial','B');
$pdf->Cell(55,5,"Black Text ",1,0,'C');
$pdf->SetXY($coordXbase,$coordY);

//Setting the text color to red
$pdf->SetTextColor(194,8,8);

//Printing another cell, over the other
$pdf->SetFont('Arial','B');
//Give some space from the left border, and print the red text after the black text that is in the cell behind this one.
$pdf->Cell(55,5,"                        Red Text",0,0,'C');
$pdf->SetXY($coordXbase,$coordY);

//Setting the text color back to back, in the next cells.
$pdf->SetTextColor(0,0,0);

The result was this:

As I was a little rush, I had no time to create some function to help with this, but this would be a good starting point idea :)

P.S.: Tell if you guys find an easier way.

Answer 2

I needed that functionality too. This is the function I written to do a simple colored string:

function cellMultiColor($stringParts) {
    $currentPointerPosition = 0;
    foreach ($stringParts as $part) {
        // Set the pointer to the end of the previous string part
        $this->_pdf->SetX($currentPointerPosition);

        // Get the color from the string part
        $this->_pdf->SetTextColor($part['color'][0], $part['color'][1], $part['color'][2]);

        $this->_pdf->Cell($this->_pdf->GetStringWidth($part['text']), 10, $part['text']);

        // Update the pointer to the end of the current string part
        $currentPointerPosition += $this->_pdf->GetStringWidth($part['text']);
    }

and you use it like this:

cellMultiColor([
    [
        'text' => 'Colored string example: ',
        'color' => [0, 0, 0],
    ],
    [
        'text' => 'red',
        'color' => [255, 0, 0],
    ],
    [
        'text' => ', ',
        'color' => [0, 0, 0],
    ],
    [
        'text' => 'blue',
        'color' => [0, 0, 255],
    ],
]);
