Sharing the specific implementation method of deleting blank elements in an array in PHP_PHP Tutorial

The specific code for us to actually use PHP to delete empty elements in an array is as follows:

<ol class="dp-xml">
<li class="alt"><span><span>function array_remove_empty(& $arr, $</span><span class="attribute"><font color="#ff0000">trim</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">true</font></span><span>)   </span></span></li>
<li class=""><span>{   </span></li>
<li class="alt">
<span>foreach ($arr as $</span><span class="attribute"><font color="#ff0000">key</font></span><span> =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> $value) {   </span>
</li>
<li class=""><span>if (is_array($value)) {   </span></li>
<li class="alt"><span>array_remove_empty($arr[$key]);   </span></li>
<li class=""><span>} else {   </span></li>
<li class="alt">
<span>$</span><span class="attribute"><font color="#ff0000">value</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">trim</font></span><span>($value);   </span>
</li>
<li class="">
<span>if ($</span><span class="attribute"><font color="#ff0000">value</font></span><span> == '') {   </span>
</li>
<li class="alt"><span>unset($arr[$key]);   </span></li>
<li class=""><span>} elseif ($trim) {   </span></li>
<li class="alt"><span>$arr[$key] = $value;   </span></li>
<li class=""><span>}   </span></li>
<li class="alt"><span>}   </span></li>
<li class=""><span>}   </span></li>
<li class="alt"><span>}  </span></li>
</ol>

The above code is the specific implementation method of deleting the blank elements of the array in PHP. I hope you can save it and collect it for future use. .
