<\/div>\nGenerate Thumbnail from PDF in PHP<\/h2>\n
The following code snippet creates thumbnail image for PDF file using PHP.<\/p>\n
\n- Specify the source PDF file from which the thumbnail image will be generated.<\/li>\n
- Specify the folder path where the PDF thumbnail will be stored.<\/li>\n
- Initialize the Imagick library and pass the PDF document page number in the Imagick() class.<\/li>\n
- Set the thumbnail image file type using the setImageFormat() function of the Imagick library.<\/li>\n
- Set the thumbnail image size using the thumbnailImage() function.<\/li>\n
- Save image in the directory using the writeImage() function.<\/li>\n<\/ul>\n

This example code snippet shows you the step-by-step process to upload PDF files and generate thumbnails from PDF using PHP.<\/p>\n
HTML Form:<\/b>
\nDefine HTML elements for file uploading form.<\/p>\n<form<\/span> action<\/span>=\"submit.php\"<\/span> method<\/span>=\"post\"<\/span> enctype<\/span>=\"multipart\/form-data\"<\/span>><\/span>\r\n <div<\/span> class<\/span>=\"form-input\"<\/span>><\/span>\r\n <label<\/span> for<\/span>=\"pdf_file\"<\/span>><\/span>PDF File<\/label<\/span>><\/span>\r\n <input<\/span> type<\/span>=\"file\"<\/span> name<\/span>=\"pdf_file\"<\/span> placeholder<\/span>=\"Select a PDF file\"<\/span> required<\/span>=\"\"<\/span>><\/span>\r\n <\/div<\/span>><\/span>\r\n <input<\/span> type<\/span>=\"submit\"<\/span> name<\/span>=\"submit\"<\/span> class<\/span>=\"btn\"<\/span> value<\/span>=\"Create Thumbnail\"<\/span>><\/span>\r\n<\/form<\/span>><\/span><\/pre>\nOn form submission, the selected file is submitted to the server-side script for process further.<\/p>\n
Server-side Script (submit.php) to Extract Text from Uploaded PDF:<\/b>
\nThe following code is used to upload the submitted file and generate thumbnail of PDF.<\/p>\n\n- Retrieve file name using $_FILES in PHP.<\/li>\n
- Get file extension using
pathinfo()<\/code> function with the PATHINFO_EXTENSION filter.<\/li>\n- Validate the file to check whether it is a valid PDF file.<\/li>\n
- Retrieve file path using
tmp_name<\/code> in $_FILES.<\/li>\n- Generate thumbnail of the PDF first page using the Imagick library and save the image in a folder.<\/li>\n<\/ul>\n
