php - How to search through a gallery of photos containing QR Codes for a character string -

-

i have folder of images, each containing qr code within picture acts unique identifier image. each qr code represents "order number" in form of "so12345"

what great if upload these photos dropbox, , type order number search box , find image contains qr code equivalent of search phrase.

is there existing service can this? or have custom written? there php library use?

assuming has done using php library, there 2 ways see doing this.

  1. each time search character phrase, has loop through each image 1 1 till either completes no matches, or finds match, format take longer , longer directory increases in size.

or

  1. have function loop through every image uploaded, , if finds qr code, decodes , either changes file name qr code value, or updates mysql row table associate qr code value file name. search function searches match in file name, or match in mysql row value.

ideally rather not reinvent wheel if necessary. if has done appreciate can offer on start accomplish this.

you upload photos google drive , name pictures qr code. search qr code in google drive , should come up.
