在PHP中将文本输出限制为50个字符[重复]

Question

This question already has an answer here:

• PHP limit length of every string in array 3 answers

I'm trying to limit my text export in PHP to only 50 characters only

How could I modify the following statement to allow this?

$list[$key]['goods_attr'] = $rows['goods_attr'];

</div>

Answer 1

You should do this in your SQL query if possible.

SELECT LEFT(subject , 50) FROM table 

Or you could do it by using substr like this:

$list[$key]['goods_attr'] = substr($rows['goods_attr'], 0, 50);
