How to align text when overlaying an image?

Question

PHP

Let's say I have a string: aaa bbb ccccccapproximately 200px wide. And I want to overlay this line on the image. But there is a moment! The text width needs to be 100px. Those. so that the text is overlaid like this:

aaa bbb
cccccc

Those. so that what does not fit into the given width is wrapped on a new line.
Is there any way to implement something like this?
In theory, you need me to specify the start coordinate, the text alignment relative to the coordinate, and the maximum width. And the text that would go beyond the specified width was transferred to a new line.

Answer 1

I will describe the algorithm.

length = 0
str = "aaa bbb cccccc"
resstr = ""
curstr = ""
for i=0; i<strlen(str); i++
    curstr .= str[i];
    if вычислить_ширину(curstr) > 100
        resstr .= curstr . "\n"
        curstr = ""
    end if
end for
resstr .= curstr

Something like this. PHP I know, I forgot only the name of the function that calculates the size of the string
