    text
    copied!<p>I am trying to make string <a href="https://en.wikipedia.org/wiki/Serial_comma" rel="nofollow">serial comma</a> from array. Here is the code I use:</p> <pre><code>&lt;?php echo "I eat " . implode(', ',array('satay','orange','rambutan')); ?&gt; </code></pre> <p>But the results I get:</p> <pre><code>I eat satay, orange, rambutan </code></pre> <p>Cannot:</p> <pre><code>I eat satay, orange, and rambutan </code></pre> <p>Yet!</p> <p>So, I made my own function:</p> <pre><code>&lt;?php function array_to_serial_comma($ari,$konj=" and ",$delimiter=",",$space=" "){ // If not array, then quit if(!is_array($ari)){ return false; }; $rturn=array(); // If more than two // then do actions if(count($ari)&gt;2){ // Reverse array $ariBlk=array_reverse($ari,false); foreach($ariBlk as $no=&gt;$c){ if($no&gt;=(count($ariBlk)-1)){ $rturn[]=$c.$delimiter; }else{ $rturn[]=($no==0)? $konj.$c : $space.$c.$delimiter; }; }; // Reverse array // to original $rturn=array_reverse($rturn,false); $rturn=implode($rturn); }else{ // If &gt;=2 then regular merger $rturn=implode($konj,$ari); }; // Return return $rturn; }; ?&gt; </code></pre> <p>Thus:</p> <pre><code>&lt;?php $eat = array_to_serial_comma(array('satay','orange','rambutan')); echo "I eat $eat"; ?&gt; </code></pre> <p>Result:</p> <pre><code>I eat satay, orange, and rambutan </code></pre> <p>Is there a more efficient way, using a native PHP function maybe?</p> <p><strong>Edit:</strong></p> <p>Based on code from @Mash, I modifying the code that might be useful:</p> <pre><code>&lt;?php function array_to_serial_comma($ari,$konj=" and ",$delimiter=",",$space=" "){ // If not array, then quit if(!is_array($ari)){ return false; }; $rturn=array(); // If more than two // then do actions if(count($ari)&gt;2){ $akr = array_pop($ari); $rturn = implode($delimiter.$space, $ari) . $delimiter.$konj.$akr; }else{ // If &gt;=2 then regular merger $rturn=implode($konj,$ari); }; // Return return $rturn; }; ?&gt; </code></pre>
