<?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

$hello = explode(',',$source);

for($index=0;$index<count($hello);$index++){

echo $hello[$index];echo "</br>";

}

<?php

//函数挺实用的

// 分隔符可以是斜线，点，或横线

$date = "04/30/1973";

list($month, $day, $year) = split ('[/.-]', $date);

echo "Month: $month; Day: $day; Year: $year<br />\n";

?>
