Simple arrangement of PHP arrays

This article mainly shares with you the simple arrangement of PHP arrays. You can find the function by defining the function variable name: function aMethod() { echo "I am a method";} function bMethod() { echo "I am another method"; }$myFunction = "aMethod";//Define the variable $myFunction(); //Since there are brackets after the variable, find the function function with the same name.

The array subscript can be specified

$arr = array(1=>"a","b","c","d");  echo $arr[3]; //打印c

The date for loop is an odd-numbered line output in bold font to traverse the date

 function boldTitle($inputText) {

         echo "<B>{$inputText}</B>";
       }

        date_default_timezone_set("UTC");
         
         $i = 0;

       for ($currentDate = date("U");date("l",$currentDate) != "Monday";$currentDate += (60*60*24)) {
          
          if ($i++%2==0) {

            echo "<li>".boldTitle(date("l",$currentDate))."</li>";

          }else {

              echo "<li>".date("l",$currentDate)."</li>";
          } 
        }
