metadata - How can I read XMP data from a JPG with PHP? -

-

Support for PHP and EXIF ​​and IPTC metadata have been created, but I can not find any way to read XMP?

.

The following shows this process (I am using but every other XML API or even simple and clever string parsing can give you similar results): 

  $ content = file_get_contents ($ image); $ Xmp_data_start = strpos ($ content, '& lt; x: xmpmeta'); $ Xmp_data_end = strpos ($ content, '& lt; / x: xmpmeta & gt;'); $ Xmp_length = $ xmp_data_end - $ xmp_data_start; $ Xmp_data = substr ($ content, $ xmp_data_start, $ xmp_length + 12); $ Xmp = Simple XMLload_string ($ xmp_data); Just two comments:  
     
  •  XMP uses XML namespaces heavily, so you have to keep an eye on it, when XMP data will have to be parsed Xml tool  
  •  Considering the potential size of image files, you probably will not be able to use it because this function loads the entire image in memory to open file-stream processing and key-sequence  and lt; X: xmpmeta  more data  and lt; / X: xmpmeta> To check the amount of data for , the memory footprint.

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
