Local connection restricted or no connection PHP save remote picture to local method

Today, when we collate the information, we find a function that we have found before, through which we can implement the above function.
Main functions:

Copy the Code code as follows:

function Grabimage ($url, $filename = "") {
if ($url = = "") return false;
if ($filename = = "") {
$ext =STRRCHR ($url, ".");
if ($ext! = ". gif" && $ext! = ". jpg" && $ext! = ". png") return false;
$filename =date ("Ymdhis"). $ext;
}
Ob_start ();
ReadFile ($url);
$img = Ob_get_contents ();
Ob_end_clean ();
$size = strlen ($img);
$FP 2= @fopen ($filename, "a");
Fwrite ($fp 2, $img);
Fclose ($fp 2);
return $filename;
}

Get the code for a picture:

Copy the Code code as follows:

$img =grabimage ("Http://www.baidu.com/img/baidu_logo.gif", "logo.gif");
if ($img) {
Echo ';
}else{
echo "false";
}

This is an example of saving Google's logo, and the captured image is saved under a sibling directory.
Get a series of regular pictures (for example: 100 pictures named with the number 1-100):

Copy the Code code as follows:

for ($i =1; $i <=100; $i + +) {
$img =grabimage ("http://www.yourimagesite.com/images/$i. gif", "images/$i. gif");
}

The above www.yourimagesite.com is the URL of the picture, you need to modify it, after the execution of the program, all the pictures will be saved to the images directory.

The above describes the local connection is limited or no connection PHP to save the remote image to the local, including local connection limited or no connection content, I hope to be interested in PHP tutorial friends helpful.
