Puzzle: article content in a MySQL field, read the content in PHP, how to put the number inside the picture content output

Puzzle: article content in MySQL a field, read the content in PHP, how to put the number inside, to the picture content output!
Php+mysql questions:
The article content in a MySQL field, in order to prevent copying collection, intends to the content of the "Arab" numbers, output as a picture format, my idea is: with PHP first read the content of the article, and then judge the number inside, whatever the number, it is displayed as a picture! Effect


Problem: The number of an article in more than one place, some reach hundreds of places, and some numbers are with a decimal point, such as 12.3, so many numbers, how to output?

Tip: The article is to introduce the market, all the numbers behind have a Chinese character "Yuan", such as 15.6 yuan, 14-17 yuan, 48 yuan and so on.

can you pass some of the characters in front of "yuan" into the picture output?

my points are not much, altogether only 25 points, all gave!
