Problems with phpquery collection

Questions collected using phpquery I used phpquery to collect webpage content

Below is

PhpQuery: newDocumentFile ($ url); $ img = pq ('. productImageGrid # prodImageCell ')-> html (); echo $ img; $ img_txt = pq ('. productImageGrid # prodImageCell ')-> text ();

$ Img_txt is a null value with no content
$ Img both echo and print_r show images
How can I convert $ img into a string? I need to save it to the database.




The above is the code displayed in the browser. I just want to save the code to the database.

Reply to discussion (solution)

I don't know how to output $ img because
$ The img type is string

Since the string is directly stored in the database

How can I output it to imgurl =
I directly used ehco to display the image on the page.
