I read this
http://yuncode.net/code/c_594.
is successful after using it. It doesn"t seem to be misused, and it doesn"t seem to have a bad effect.
it"s just a little more skeptical
question 1
this is to multiply the height by 0.9 if you exceed the 600x600, and directly discount by 10%.
is it possible to "specify the degree and height"? Suppose I want 550x250?
Chong Chong: I found it integrated into
$new_width = 550;
$new_height = 250;
will not flatten the film in an equal proportion, but directly flatten our film.

question 2
//75
imagejpeg($image_wp, $imgdst,75);
I don"t quite understand this sentence, so what does the number 75 stand for? The lower it is, the more arrogant it is. The smaller the file size?
question 3
are both jpg and jpeg processed at case 2:
?
question 4
is there a more appropriate function to upgrade this function? To make it more efficient? This kind of thing. Curiously, the article has been published for more than a year
question 5
what can I do if the film is lower than the height I specified? On the contrary, it is said that it will increase size
