-<p>Enables you to send an attachment. Put the file path/name in the first
-parameter. For multiple attachments use the method multiple times.
-For example:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo1.jpg&#39;</span><span class="p">);</span>
-<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo2.jpg&#39;</span><span class="p">);</span>
-<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo3.jpg&#39;</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>To use the default disposition (attachment), leave the second parameter blank,
-otherwise use a custom disposition:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;image.jpg&#39;</span><span class="p">,</span> <span class="s1">&#39;inline&#39;</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>You can also use a URL:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;http://example.com/filename.pdf&#39;</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>If you&#8217;d like to use a custom file name, you can use the third parameter:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;filename.pdf&#39;</span><span class="p">,</span> <span class="s1">&#39;attachment&#39;</span><span class="p">,</span> <span class="s1">&#39;report.pdf&#39;</span><span class="p">);</span>
-</pre></div>
-</div>
-<p>If you need to use a buffer string instead of a real - physical - file you can
-use the first parameter as buffer, the third parameter as file name and the fourth
-parameter as mime-type:</p>
-<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="nv">$buffer</span><span class="p">,</span> <span class="s1">&#39;attachment&#39;</span><span class="p">,</span> <span class="s1">&#39;report.pdf&#39;</span><span class="p">,</span> <span class="s1">&#39;application/pdf&#39;</span><span class="p">);</span>
