php连接函数implode与分割explode的深入解析_PHP
目前学习php的人有很多,很多进行php培训的朋友在学习中总会问到这样一个问题:php连接函数implode是什么呢?
php可以将字符串分割成数组,同时翻过了也可以将数组连接成字符串,确切的说是可以将数组元素连接成字符串,有了这两个函数我们就可以在数组与字符串之间进行自由转换了,下面看正文的例子吧。
implode() 连接函数:
此函数实现将数组元素连接成字符串,连接之前我们要给它两个参数,一个是连接符一个是将要被连接的数组
注意是一维数组哦,多维小编很少用,不过大家可以试试。
例子:
复制代码 代码如下:
$array = array('a' => 1, 'b'=>2, 'c'=>3, 'd'=>4);
$string = implode("-",$array)
echo $string;
//==== 结果就是:1-2-3-4;
?>
explode() 分割函数:
此函数功能是将字符串分割到数组里面,我们依然是给它两个参数,一个是分隔符一个是将要被分割的字符串
注意这个分隔符是字符串中存在的哦,我们依然用上面的结果作为例子
复制代码 代码如下:
$string = "1-2-3-4";
$array = explode("-",$string);
echo "
";<br> print_r($array);<br>//==== 结果就是上面例子定义的数组喽,这里小编就不写出来了<br>?><br>
