How to use webcam in php Part 2



In this tutorial you will find that How you can use Webcam in PHP using HTML5 and Jquery.

In this tutorial you will see that we have used the code of my blog post for showing the code you can also download the code from my blog post below is the link of the article which i have written for showing the Webcam in PHP.

In this video we have describe the working of buttons and saving the clicked image to the database. You will find 2 types for saving the image to the database. One is local storage under the folder and another one is Base64 image transform than save the image to the database.

Important Note – The whole package will run perfectly over the localhost but if you put the package over the server than you need to switch to HTTPS.

If you want working example of the tutorial than you can also download the whole example from the github. You will find the download link at the bottom of the article.

  4. Hello Vivekmoyal, Thanks a lot for your tutorial. I have managed to create webcam but when I am trying to save to local host I get the error " Upload failed with status 500 " Any ideas why please ??

  5. Hello Vivekmoyal, Thanks for your tutorial. I'm using it on an application I developed that works on a local server, but I'm having problems when using android or Safari (can't access the camera). Do you know how I can solve the problem? Thank you very much
