array_chunk
- 版本：>= 4.2
- 说明：
array_chunk(array $input, int $size, [, bool $preserve_keys=false])
此函数的作用是将数组分块，当我们对数组里的数据做分批处理时可以使用此函数。 - 参数
- input
要处理的数组。 - size
数组块的大小 - preserve_keys
是否保留原来的数据的key,默认为不保留。
- input
- 例子
<span>$input</span>=<span>array</span>(<span>"a"</span>=><span>"php"</span>,<span>"b"</span>=><span>"c"</span>,<span>"c"</span>=><span>"c++"</span>,<span>"d"</span>=><span>"python"</span>,<span>"e"</span>=><span>"ruby"</span>);
<span>$output</span> = array_chunk(<span>$input</span>, <span>2</span>);
<span>#output=></span><span>Array</span>
(
[<span>0</span>] => <span>Array</span>
(
[<span>0</span>] => php
[<span>1</span>] => c
)
[<span>1</span>] => <span>Array</span>
(
[<span>0</span>] => c++
[<span>1</span>] => python
)
[<span>2</span>] => <span>Array</span>
(
[<span>0</span>] => ruby
)
)
<span>$output2</span> = array_chunk(<span>$input</span>, <span>2</span>, <span>true</span>);
<span>#output2=> </span><span>Array</span>
(
[<span>0</span>] => <span>Array</span>
(
[a] => php
[b] => c
)
[<span>1</span>] => <span>Array</span>
(
[c] => c++
[d] => python
)
[<span>2</span>] => <span>Array</span>
(
[e] => ruby
)
)
<span>#注意子数组中的key还是保留原来数组中的key</span>').addClass('pre-numbering').hide();
$(this).addClass('has-numbering').parent().append($numbering);
for (i = 1; i ').text(i));
};
$numbering.fadeIn(1700);
});
});
以上就介绍了[php函数]--数组函数--array_chunk，包括了方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
