Use php to handle all img tags in html code

Php is used to process all img tags in a piece of html code. there is a piece of html code that contains many tags and a lot of img tags. now, you need to extract the src Image addresses of all img tags in php language, and process them through a program to generate the image addresses under your server, replace the original src Image address with the address processed by our program. Make sure that all img tags in html code are processed by php in the image.

Php html image sharing:
------ Solution --------------------
This can be implemented using regular expressions.

$ Url = "http://www.ggggggg.com ";

// The file_get_contents () function reads the entire file into a string.

$ String = file_get_contents ($ url );

// The preg_match_all function matches the global regular expression.

Preg_match_all ("/] *) \ s * src = ('
------ Solution --------------------
\ ") ([^ '\"] + )('
------ Solution --------------------
\")/",

$ String, $ matches); // enclosed by quotation marks

// Preg_match_all ("/] *) \ ssrc = ([^ \ s>] +)/", $ string, $ matches); // no quotation marks

$ New_arr = array_unique ($ matches [0]); // Remove repeated values from the array

Foreach ($ new_arr as $ key ){

Echo $ key ."
";

}

?>

All captured images are displayed in the code running result.
------ Solution --------------------
$ String = 'Your content ';

Preg_match_all ("/] *) \ s * src = ('
------ Solution --------------------
\ ") ([^ '\"] + )('
------ Solution --------------------
\ ")/", $ String, $ matches );
$ New_arr = array_unique ($ matches [2] [0]); // Remove repeated values from the array
Foreach ($ new_arr as $ key => $ val ){
$ Picurl = get_name ($ val); // address of the processed image
Str_replace ($ val, $ picurl, $ string );
}
Function get_name ($ pic_item, $ path = 'upload /')
{
$ Pic_name = paipath.get_unique().'.jpg '; // name the timestamp in microseconds.
$ Write_fd = @ fopen ($ pic_name, "wb ");
@ Fwrite ($ write_fd, CurlGet ($ pic_item ));
@ Fclose ($ write_fd );
Return $ pic_name;
