PHP gets the main color of the image

The image extension of PHP is used in the code, so before using it, you need to install the Imagick extension of PHP. The specific installation is as follows (under window):

<code><span><span><?php</span><span>$average</span> = <span>new</span> Imagick(<span>"./fruit/143511081321676_593.jpg"</span>);
<span>$average</span>->quantizeImage( <span>10</span>, Imagick::COLORSPACE_RGB, <span>0</span>, <span>false</span>, <span>false</span> );
<span>$average</span>->uniqueImageColors();
<span><span>function</span><span>GetImagesColor</span><span>( Imagick <span>$im</span> )</span>{</span><span>$colorarr</span> = <span>array</span>();
    <span>$it</span> = <span>$im</span>->getPixelIterator();
    <span>$it</span>->resetIterator();
    <span>while</span>( <span>$row</span> = <span>$it</span>->getNextIteratorRow() ){
        <span>foreach</span> ( <span>$row</span><span>as</span><span>$pixel</span> ){
            <span>$colorarr</span>[] = <span>$pixel</span>->getColor();
        }
    }
    <span>return</span><span>$colorarr</span>;
}
<span>$colorarr</span> = GetImagesColor(<span>$average</span>);
<span>foreach</span>(<span>$colorarr</span><span>as</span><span>$val</span>){
    <span>$r</span> += <span>$val</span>[<span>'r'</span>];
    <span>$g</span> += <span>$val</span>[<span>'g'</span>];
    <span>$b</span> += <span>$val</span>[<span>'b'</span>];
    <span>echo</span><span>"<divr']},{$val['g']},{$val['b']});width:50px;height:50px;float:left;'></div>"</span>;
}
<span>$r</span> = round(<span>$r</span>/<span>10</span>);
<span>$g</span> = round(<span>$g</span>/<span>10</span>);
<span>$b</span> = round(<span>$b</span>/<span>10</span>);
<span>echo</span><span>"<br><div></div>"</span>;
<span>?></span></span></span></code>

The above introduces PHP to obtain the main color of the picture, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
