Wrap and center text in gd and php

Question

I have a line of text that I need to wrap and center in a GD image. I also use the ttf font. Can anything help me?

I managed to get some text to do the following, but now I need to center it:

function wrap($fontSize, $angle, $fontFace, $string, $width){

    $ret = "";

    $arr = explode(' ', $string);

    foreach ( $arr as $word ){

        $teststring = $ret.' '.$word;
        $testbox = imagettfbbox($fontSize, $angle, $fontFace, $teststring);
        if ( $testbox[2] > $width ){
            $ret.=($ret==""?"":"\n").$word;
        } else {
            $ret.=($ret==""?"":' ').$word;
        }
    }

    return $ret;
}

Answer 1

Center both horizontally and vertically: get half the height from imagettfbbox of the whole text (with new lines) and align it with half the height of your image ( $start_x).

, ttfbox ($h) ($w). , + $w $start_x, $h $start_x, , .
