php怎么将数组转换为字符串
php将数组转换为字符串的方法:可以使用implode()函数分割数组,该函数会返回由数组元素组成的字符串。还可以利用循环遍历数组元素并将其拼接成字符串。
php将数组转换为字符串的方法
方法1:利用内置的implode函数
implode() 函数可以将一个一维数组转化为字符串,其语法格式如下:
implode($glue, $array) //或者 implode($array)
其中,$glue 用来设置一个字符串,表示使用 $glue 将数组每个元素连接在一起,默认情况下 $glue 为空字符串;$array 为需要转换的数组。
提示:implode() 函数的 $glue 参数是可选的,可以省略。
示例:使用 implode() 函数将数组转换为字符串。
<?php $arr = array('Hello','World!','Beautiful','Day!'); echo implode(" ",$arr); ?>
输出:
Hello World! Beautiful Day!
方法2:利用循环遍历数组元素拼接成字符串
<?php // PHP数组转字符串的方法 // 方法一:implode(glue, pieces) $arr = ['Lucy','Mike','Jery','Haly']; $str = implode(',', $arr); // var_dump($str); //方法二,利用循环遍历数组元素拼接成字符串 $arr1 = ['Lucy','Mike','Jery','Haly']; $str1 = ''; foreach ($arr1 as $key => $value) { $str1 .=','.$value; } var_dump($str1);
