How to automatically start a download in PHP ?
This post deals with creating a start downloading file using PHP. The idea is to make a download button which will redirect you to another page with the PHP script that will automatically start the download.
Creating a download button:
<!DOCTYPE html>
< html >
< head >
< meta name = "viewport" content =
"width=device-width, initial-scale=1" >
< style >
.btn {
background-color: limeGreen;
border: none;
color: white;
padding: 12px 30px;
cursor: pointer;
font-size: 20px;
}
.btn:hover {
background-color: green;
}
</ style >
</ head >
< body >
< center >
< p >Auto width:</ p >
< button class = "btn" >
< i class = "fa fa-download" >Download</ i >
</ button >
< p >Full width:</ p >
< button class = "btn" style = "width:100%" >
< i class = "fa fa-download" >Download</ i >
</ button >
</ center >
</ body >
</ html >

if ( file_put_contents ( $file_name ,
file_get_contents ( $url ))) {
