php分割字符串explode函数的用法

PHP数组和explode函数应用实例，供大家学习参考。

例1：

<?php
$province = array("北京","上海","天津","重庆","河北","山西","内蒙古","辽宁","吉林","黑龙江","江苏","浙江","安徽","福建","江西","山东","河南","湖北","湖南","广东","广西","海南","四川","贵州","云南","西藏","陕西","甘肃","宁夏","青海","新疆","香港","澳门","台湾","其他");
echo count($province);//数组成员个数
echo "<br/>";

if(is_array($province)){//检测变量是否是数组
  echo "嗯,真是个数组啊";
}
echo "</br>";

for($index=0;$index<count($province);$index++){//数组循环
echo $province[$index];
echo "</br>";
}
?>

例2：

<?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>";
}
?>

例3：

<?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";
?>
