Re: php: assignment operator

So, if there was not the assignment operator like this in the script below: .= ............... $image_tag_src.="<IMG SRC=\"$image_src\" BORDER=\"0\">" ............... but let's say a = the output would echo ONE placeholder for the IMG SRC from 0 through 9 - however when the 10th time the page was loaded it would still be in the *same* IMG SRC holder and there never be a second IMG SRC holder - to the right - (10 through 99), a third to the right of the second (100 through 999), etc. Please advise. Thank you for your time. TR ................................. for($i=0; $i<strlen($counter); $i++) { $image_src=$image_dir. "/" .substr($counter, $i, 1) . ".jpg"; $image_tag_src.="<IMG SRC=\"$image_src\" BORDER=\"0\">"; // assignment operator .= } ...............................
