How to center text between 2 points php?

Question

I am trying to center some text between to points. The text is dynamic and should be centered no matter what it contains.

I am trying the following:

    $dims = imagettfbbox(130, 0, './Calibri.ttf', "JULY");

$width = ($dims[2])-($dims[0]);

imagettftext($my_img , 130, 0, 1196-($width/2) , 700, $text_colour, './Calibri.ttf', "JULY");

I have a point at x = 711 and a point at x = 1907 and this is where I get the 1196 from because 1907-711 = 1196.

In my logic the 1196-($width/2) should work as the parameter is the first pixel of the text.

But as it can be seen on the image, it is not centered.

Answer 1

From your explanation I understood that 1196-($width/2) is wrong.

You should find the middle of the box, laying between x = 711 and x = 1907:

$x_center = 711 + (1907 - 711) / 2 
$x_start = $x_center - ($width / 2)

Hope it helps.
