PHP数组去重/高德地图API

数组去重

$term  =  array_column ( $grade ,  'term' );

$term  =array_flip(array_flip($term));

print_r($term);

效果:



原理:

array_flip()：

函数返回一个反转后的数组，如果同一值出现了多次，则最后一个键名将作为它的值，所有其他的键名都将丢失。
如果原数组中的值的数据类型不是字符串或整数，函数将报错。

两次键和值交换,由于PHP不允许键名重复,就达到去重的效果了。

第二种方法:

print_r(array_unique($term));

array_unique() 函数移除数组中的重复的值，并返回结果数组。
当几个数组元素的值相等时，只保留第一个元素，其他的元素被删除。
返回的数组中键名不变。
