What is this? This is a QR Code: a machine-readable image-based code consisting of black and white squares. QR Codes are typically used for storing URLs and other information for reading by a smart devices like smart phones.
When scanned by an appropriate app on your mobile device, you are redirected to the embedded URL of this page. View this page with one device (desktop or another mobile device), and then scan the
QR Code with your mobile device. This makes it quicker and easier to browse a page discovered on one device on your mobile device without manually entering the URL in the mobile device browser address bar.
⚬ If you are using an Android phone, you can find a QR Code reading app at Google Play on your device.
⚬ If you are using an iOS device (iPhone, iPad, etc.), you can find a QR Code reading app at the Apple iTunes App Store on your device.
⚬ If you are using a Windows phone, you can find a QR Code reading app at the Microsoft Store on your device.
(pay attention to line endings - PHP uses a native function to
parse the input, so a Mac file won't work on Unix).
Setting use_include_path to TRUE will result
in PHP trying to open the file along the standard include path as per
the include_path directive.
This is used for local files, not URLs.
Returns an array with all the parsed meta tags.
The value of the name property becomes the key, the value of the content
property becomes the value of the returned array, so you can easily use
standard array functions to traverse it or access single values.
Special characters in the value of the name property are substituted with
'_', the rest is converted to lower case. If two meta tags have the same
name, only the last one is returned.
Example #2 What get_meta_tags() returns
<?php // Assuming the above tags are at www.example.com $tags = get_meta_tags('http://www.example.com/');
// Notice how the keys are all lowercase now, and // how . was replaced by _ in the key. echo $tags['author']; // name echo $tags['keywords']; // php documentation echo $tags['description']; // a php manual echo $tags['geo_position']; // 49.33;-86.59 ?>
Only meta tags with name attributes will be parsed. Quotes are not required.
