PHP数组的合并、拆分、区别取值函数集

都说PHP的数组功能很强大、只有真正用于项目工作当中才能够感受得到,至少我认为是,现在已慢慢的发觉其中的奥秘了……

合并数组有三个函数

1.array_combine()

携带两个参数数组,参数数组一的值作新数组的键,参数数组二的值作新数组的值。很简单。

例子:

$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);

print_r($c);
?>

上例将输出:

Array
(
[green] => avocado
[red] => apple
[yellow] => banana
)
