如何创建数据库的一个数组？ [英] How to create an array from database?

问题描述

请帮我创建从我的数据库的字段的数组。那场具有以逗号分隔的记录。下面是说明：

  ID | article_title_fld | article_tags_fld |
-------------------------------------------------- --------------------
1 |学习PHP | PHP，编码，脚本|
3 | JavaScript的教程| JavaScript的，脚本，教程|
4 |用CSS样式| CSS，教程，网页设计|
 

我要收集所有记录在 article_tags_fld ，然后放入1阵列。也许我把它命名为 $数组1 ，然后如下打印出来：

 阵列
（
[0] =＆GT; PHP
[1] =＆GT;编码
[2] =＆GT;脚本
[3] =＆GT; JavaScript的
[4] =＆GT;脚本
[5] =＆GT;教程
[6] =＆GT; CSS
[7] =＆GT;教程
[8] =＆GT;网页设计
）
 

解决方案

  $ ARRAY1 =阵列（）;
$结果= mysql_query（选择article_tags_fld FROM MY_TABLE）;
而（$行= mysql_fetch_assoc（$结果））{
   $数组1 = array_merge（$数组1，array_map（'微调'，爆炸（，$行['article_tags_fld']）））;
}
 

爆炸将被分隔符分割字符串。

array_merge 将结合两个数组。

array_map 将适用于装饰的所有元素。

修剪将删除你的标签两边的空白。

Please help me to create an array from a field of my DB. That field has records separated by comma. Below is the illustration:

ID | article_title_fld         | article_tags_fld                     |
----------------------------------------------------------------------
1  | Learn PHP                 | PHP, coding, scripting               |
3  | Javascript Tutorial       | Javascript, scripting, tutorial      |
4  | Styling with CSS          | CSS, tutorial, web design            |

I want to collect all records in the article_tags_fld then put it into 1 array. Perhaps I named it $array1, and the print out as below:

Array
(
[0] => PHP
[1] => coding
[2] => scripting
[3] => Javascript
[4] => scripting
[5] => tutorial
[6] => CSS
[7] => tutorial
[8] => web design
)

解决方案

$array1 = array();
$result = mysql_query("SELECT article_tags_fld FROM MY_TABLE");
while ($row = mysql_fetch_assoc($result)) {
   $array1 = array_merge($array1, array_map('trim', explode(",", $row['article_tags_fld'])));
}

explode will split a string by a delimiter.

array_merge will combine two arrays.

array_map will apply trim to all elements.

trim will remove any white space on either side of your tags.
