Two ways to split strings with commas in php

The first method

<?php
//利用 explode 函数分割字符串到数组
$source = "hello1,hello2,hello3,hello4,hello5";//按逗号分离字符串
$hello = explode(&#39;,&#39;,$source);
 
for($index=0;$index<count($hello);$index++){
echo $hello[$index];echo "</br>";
}
?>

The second method

<?php
//split函数进行字符分割
// 分隔符可以是斜线，点，或横线
$date = "04/30/1973";
list($month, $day, $year) = split (&#39;[/.-]&#39;, $date);
echo "Month: $month; Day: $day; Year: $year<br />\n";
?>
