You can do this using the GD library, but it requires you to have the font available as a .TTF file:

Code Select Expand


<?php

function fixbbox($bbox) {
   $xcorr=0-$bbox[6]; //northwest X
   $ycorr=0-$bbox[7]; //northwest Y
   $tmp_bbox['left']=$bbox[6]+$xcorr;
   $tmp_bbox['top']=$bbox[7]+$ycorr;
   $tmp_bbox['width']=$bbox[2]+$xcorr;
   $tmp_bbox['height']=$bbox[3]+$ycorr;
   
   return $tmp_bbox;
}

$font = 'arial.ttf';
$fontSize = 9.5;
$text = 'Test 123';

$bbox = fixbbox(imagettfbbox($fontSize, 0, $font, $text));
echo 'The text is ', $bbox['width'], ' pixels wide';
?>

[/i](don't ask about the fixbbox function, I don't know how it works, as I didn't write it. I just got it from the PHP website, under the user comments)[/i]

Replace arial.ttf with the name of the font, 9.5 with the font size and Test 123 with the text. On my computer, this shows output like:

The text is 46 pixels wide
