Today I will show simple, but simetimes very usefull example, how to remove empty paragrapth from your text.
My code:
<?php $html = "abc<p></p><p>dd</p><b>non-empty</b>"; $pattern = "/<p[^>]*><\\/p[^>]*>/"; //$pattern = "/<[^\/>]*>([\s]?)*<\/[^>]*>/"; use this pattern to remove any empty tag echo preg_replace($pattern, '', $html); // output //abc<p>dd</p><b>non-empty</b> ?>
Very simple 🙂
This is very easy. Vimeo has API. This is the Vimeo Simple API docs.
You should make a Video Request
To get data about a specific video, use the following url:
I recently had a hard drive go bad on me which actually turned out to be a hard drive going bad. There was definitely something goofy going on with access to the drive. I keep daily backups but a perfect backup of a corrupted source is no good. My most important files are my digital photos, mostly JPG images. I did some visual spot checking but once I hit the 1500 photos I looked for a better alternative. Here’s what I came up with. (This works on Linux. You’ll have to alter your process on Windows and Macs but the principles are the same.)
This is a simple php example how to add http:// to the url.
function addhttp($url) {
if (!preg_match("~^(?:f|ht)tps?://~i", $url)) {
$url = "http://" . $url;
}
return $url;
}
Recognizes ftp://, ftps://, http:// and https:// in a case insensitive way.
This regex grabs the ID from all of the various URLs I could find… There may be more out there, but I couldn’t find reference of them anywhere.
At grub-boot loader screen select Recovery mode the version of the kernel that you wish to boot and type e for edit. Select the line that starts with kernel and type e to edit the line.
Go to the end of the line and type init=/bin/bash as a separate one word (press the spacebar and then type init=/bin/bash). Press enter key to exit edit mode.
Back at the GRUB screen, type b to boot into single user mode. This causes the system to boot the kernel and run /bin/bash instead of its standard init. This will allow us gain root privileges (w/o password) and a root shell.
If you wanna reset root password remount paritions
Code:
mount -rw -o remount /
Setup root password
Code:
passwd
Some days ago I have a problem with my server and all my innodb tables were locked. And now I want to tell, how I tried to repair these tables.
First of all, I tried to do force recovery. In mysql config file enable force recovery. Set innodb_force_recovery = 1 and try to do mysqldump. If it not work, try to increase innodb_force_recovery value to 6. Default innodb_force_recovery value is 0. After you change innodb_force_recovery value, restart mysql.
Now I will try to tell how we can stream video in website. We can do it by vlc plugin “WebPlugin”. To view video on your pages, you can build custom pages that will use the advanced features of this plugin. With Javascript functions you can easy control video player.
