asp函数split()对应php函数explode()

<?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($i=0;$i<count($hello);$i++){
echo $hello[$i];echo "</br ";
}
? 

$newstr = substr($str,0,strlen($str)-1); 

  $date = "04,30"; 
  list($month, $day) = split ('[,.-]', $date); 
  echo "Month: $month; Day: $day;<br / \n";

<meta charset="utf-8" / 
<?php 
$a1="206,206,206,201,206,201";
//$array = explode(',', $a1); //字符串组成数组
$array1=implode(",",array_unique(explode(',', $a1)));
 print_r($array1);
? 

<?php
  $a=array("a"= "Cat","b"= "Dog","c"= "Horse");
  print_r(array_values($a));
  // 输出：
  // Array ( [0] =  Cat [1] =  Dog [2] =  Horse )
? 

$a="303,304,305,306,307";
$a = explode(',',$a);
echo count($a);

<script language="javascript"  
str="2,2,3,5,6,6"; //这是一字符串 
var strs= new Array(); //定义一数组 
strs=str.split(","); //字符分割 
for (i=0;i<strs.length ;i++ ) 
{ 
document.write(strs[i]+"<br/ "); //分割后的字符输出 
} 
</script  

// 示例 1 $pizza = "piece1 piece2 piece3 piece4 piece5 piece6"; 
$pieces = explode(" ", $pizza); 
echo $pieces[0]; // piece1 
echo $pieces[1]; // piece2 

$array = array('a' =  1, 'b'= 2, 'c'= 3, 'd'= 4);
$string = implode("-",$array)
echo $string;
//==== 结果就是：1-2-3-4;
