Is there any way to put 2 arrays in the same foreach?

Let me explain what I need, I'm using the WideImage class to resize the images, I need to grab the image extension to save it later. My problem is, how can I get the length of each array image?

I can even do with a foreach type like this:

foreach ($image as $imagem) {
    foreach ($imagemExtensao as $extensao) {
        $extensaoDaImagem = pathinfo($extensao, PATHINFO_EXTENSION); 
        $imagemFinal = $imagem->resize(400, 300);
        $geraNome = md5(time().rand());
        $imagemFinal->saveToFile('imagens/usuarios/' . $geraNome .'.'.$extensaoDaImagem);
        $nomeCompleto = $geraNome.'.'.$extensaoDaImagem;
    }
}

But it duplicates the images, the names, everything. So I have to do it once, or if you have another idea.

If there are two "parallel" arrays, numerically indexed, and with corresponding indexing, just loop one of them, and use the same index in the other. For example:

foreach ($image as $indice => $imagem) {
    $extensao = $imagemExtensao[$indice];
    $extensaoDaImagem = pathinfo($extensao, PATHINFO_EXTENSION); 
    $imagemFinal = $imagem->resize(400, 300);
    $geraNome = md5(time().rand());
    $imagemFinal->saveToFile('imagens/usuarios/' . $geraNome .'.'.$extensaoDaImagem);
    $nomeCompleto = $geraNome.'.'.$extensaoDaImagem;
}
