Relevant Search: With Applications for Solr and Elasticsearch

For more in depth reading about search, ranking and generally everything you could ever want to know about how lucene, elasticsearch or solr work under the hood I highly suggest this book. Easily one of the most interesting technical books I have read in a long time. If you are tasked with solving search relevance problems even if not in Solr or Elasticsearch it should be your first reference. Amazon Affiliate Link

426<h1>Alternate PHP Syntax for View Files<a class="headerlink" href="#alternate-php-syntax-for-view-files" title="Permalink to this headline"></a></h1>
427<p>If you do not utilize CodeIgniter’s <a class="reference internal" href="../libraries/parser.html"><span class="doc">template
428engine</span></a>, you’ll be using pure PHP in your
429View files. To minimize the PHP code in these files, and to make it
430easier to identify the code blocks it is recommended that you use PHPs
431alternative syntax for control structures and short tag echo statements.
432If you are not familiar with this syntax, it allows you to eliminate the
433braces from your code, and eliminate “echo” statements.</p>
434<div class="section" id="automatic-short-tag-support">
435<h2>Automatic Short Tag Support<a class="headerlink" href="#automatic-short-tag-support" title="Permalink to this headline"></a></h2>
436<div class="admonition note">
437<p class="first admonition-title">Note</p>
438<p class="last">If you find that the syntax described in this page does not
439work on your server it might be that “short tags” are disabled in your
440PHP ini file. CodeIgniter will optionally rewrite short tags on-the-fly,
441allowing you to use that syntax even if your server doesn’t support it.
442This feature can be enabled in your <em>config/config.php</em> file.</p>
443</div>
444<p>Please note that if you do use this feature, if PHP errors are
445encountered in your <strong>view files</strong>, the error message and line number
446will not be accurately shown. Instead, all errors will be shown as
447<code class="docutils literal"><span class="pre">eval()</span></code> errors.</p>
448</div>
449<div class="section" id="alternative-echos">
450<h2>Alternative Echos<a class="headerlink" href="#alternative-echos" title="Permalink to this headline"></a></h2>
451<p>Normally to echo, or print out a variable you would do this:</p>
452<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nv">$variable</span><span class="p">;</span> <span class="cp">?&gt;</span>
453</pre></div>
454</div>
455<p>With the alternative syntax you can instead do it this way:</p>
456<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?=</span><span class="nv">$variable</span><span class="cp">?&gt;</span>
457</pre></div>
458</div>
459</div>
460<div class="section" id="alternative-control-structures">
461<h2>Alternative Control Structures<a class="headerlink" href="#alternative-control-structures" title="Permalink to this headline"></a></h2>
462<p>Controls structures, like if, for, foreach, and while can be written in
463a simplified format as well. Here is an example using <code class="docutils literal"><span class="pre">foreach</span></code>:</p>
464<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">ul</span><span class="o">&gt;</span>
465
466<span class="o">&lt;?</span><span class="nx">php</span> <span class="k">foreach</span> <span class="p">(</span><span class="nv">$todo</span> <span class="k">as</span> <span class="nv">$item</span><span class="p">)</span><span class="o">:</span> <span class="cp">?&gt;</span>
467
468        <span class="p">&lt;</span><span class="nt">li</span><span class="p">&gt;</span><span class="cp">&lt;?</span><span class="o">=</span><span class="nv">$item</span><span class="cp">?&gt;</span><span class="p">&lt;/</span><span class="nt">li</span><span class="p">&gt;</span>
469
470<span class="cp">&lt;?php</span> <span class="k">endforeach</span><span class="p">;</span> <span class="cp">?&gt;</span>
471
472<span class="p">&lt;/</span><span class="nt">ul</span><span class="p">&gt;</span>
473</pre></div>
474</div>
475<p>Notice that there are no braces. Instead, the end brace is replaced with
476<code class="docutils literal"><span class="pre">endforeach</span></code>. Each of the control structures listed above has a similar
477closing syntax: <code class="docutils literal"><span class="pre">endif</span></code>, <code class="docutils literal"><span class="pre">endfor</span></code>, <code class="docutils literal"><span class="pre">endforeach</span></code>, and <code class="docutils literal"><span class="pre">endwhile</span></code></p>
478<p>Also notice that instead of using a semicolon after each structure
479(except the last one), there is a colon. This is important!</p>
480<p>Here is another example, using <code class="docutils literal"><span class="pre">if</span></code>/<code class="docutils literal"><span class="pre">elseif</span></code>/<code class="docutils literal"><span class="pre">else</span></code>. Notice the colons:</p>
481<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;?</span><span class="nx">php</span> <span class="k">if</span> <span class="p">(</span><span class="nv">$username</span> <span class="o">===</span> <span class="s1">&#39;sally&#39;</span><span class="p">)</span><span class="o">:</span> <span class="cp">?&gt;</span>
