        Nel flusso di input, il carattere <code class="parameter">enclosure</code>
        può sempre essere sottoposto a escape raddoppiandolo all’interno di una stringa tra virgolette,
        producendo un singolo carattere <code class="parameter">enclosure</code>
        nel risultato analizzato.
        Il carattere <code class="parameter">escape</code> funziona in modo diverso:
        se una sequenza di caratteri <code class="parameter">escape</code> e
        <code class="parameter">enclosure</code> appare nell’input,
        entrambi i caratteri saranno presenti nel risultato analizzato.
        Quindi, per i parametri predefiniti, una riga CVS come
        <code class="literal">&quot;a&quot;&quot;b&quot;,&quot;c\&quot;d&quot;</code> avrà i campi analizzati come
        <code class="literal">a&quot;b</code> e <code class="literal">c\&quot;d</code>, rispettivamente.

 When <code class="parameter">escape</code> is set to anything other than an empty string

 through the PHP CSV functions. The default for <code class="parameter">escape</code> is
 <code class="literal">&quot;\\&quot;</code> so it is recommended to set it to the empty string explicitly.
 The default value will change in a future version of PHP, no earlier than PHP 9.0.
