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>";  }  ?>

截取去掉最后/第一个字符

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

取得数组的具体数据

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

去除数组中重复的元素值 array_unique()

  <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);  ?>

数组索引值如何重新从0开始递增

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

统计数组元素个数

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

JS split

  <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>

explode() 函数把字符串分割为数组。

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

implode() 函数把数组元素组合为一个字符串。

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