On this page, we represented to you the three principal ways that allow programmers to detect whether a given array is empty or not. Just see the examples.
if ( ($element === $search_for) || (is_array($element) && multi_array_search($search_for, $element)) ){ return true; } } return false; } $arr = array("2014", array("January", "February", "March"), "2015", array("Monday", "Tuesday")); echo multi_array_search("Tuesday"...

": OK, please check localfile: 'examplefile.txt'" . "\n"); 列举文件 以下代码用于列举存储空间bucket下的文件。默认列举100个文件。 <?php if (is_file(__DIR__ . '/../autoload.php')) { require_once __DIR__ . '/../autoload.php'; } if (is_file(__DIR__ . '/../vendor/...
