PHP多次替换

Question

I have got multidimensional array (name + image path), where some names are similar, like:

array("name" => "OpenGL", "img" => "OpenGL.png"),
array("name" => "OpenGL Lighting ( Advanced )", "img" => "OpenGL-LightingAdvanced.png")

then I replace names with images.

foreach ($extensions as $extension) {
    $ret=str_ireplace($extension['name'],'<img src="images/'.$extension['img'].'" alt="'.$extension['name'].'" />: ',$ret);
}

It works as long as array is sorted from shortest name to longest one, but in that case, longer names will never be changed, eg. OpenGL Lighting ( Advanced ) will be

<img src="images/OpenGL.png" alt="OpenGL" /></div>:  Lighting ( Advanced )

When I sort it from longes name to shortest one it is even worse, couse it will change name in src:

<img src="images/<img src="images/OpenGL.png" alt="OpenGL" />: -LightingAdvanced.png" alt="<img src="images/OpenGL.png" alt="OpenGL" />:  Lighting ( Advanced )" />: 

My only idea is to check if there isn't src="images/ or alt=" before name, if so - replace, but I have no idea how can I easily do.

Maybe sprintf will work:

foreach ( $extensions as $extension ) {
    $ret = sprintf( '<img src="images/%s" alt="%s" />: ', htmlspecialchars( $extension['img'] ), htmlspecialchars( $extension['name'] ) );
}
