I believe, every one would choose the one he knows/uses. I use Codeigniter, that's why I choose it. However, I'm planning to start learning Laravel soon. And I'd love to learn it from your courses as CI4 of Udemy, it was a great course. Hope, you could create a laravel course on Udemy soon. Thanks for your valuable courses, straightforward way of teaching clean and best practice code.

Dear Dave. You lessons are just excellent. You have a talent of explaining things in the most clear and consise way possible. Thanks for that. I managed to learn so much thanks to your videos and look forward to learn even more.
This lesson saved me time and effort trying to understand this whole process myself. This guide was easy to understand, and easy to follow along with.
A master class, thank you. I'd read the php manual pages on file uploads and was surprised how much is there. You have managed to cover and implement the most excellent summary I could have hoped for and cleared up a lot of confusion. Please keep on with these most excellent basics of php. Thanks again.
Thank you! I am getting practice on PHP and learning English by watching your videos!!!🤝
Nice work Dave! I love the way you delve deep into the sub-levels of PHP
Thank you, I really appreciate this high-quality content!
Thanks that was a really good tutorial, I now have a much better understanding of the error codes.
your videos have changed me a lot ... Thanks.

Another great video
and CodeIgnitor
Thank you, it was very interesting))
This is such a good video, GOD BLESS
Amazing tutorial.
Perfect Demo
cool video thanks
thank u so much
Thanks for the tutorial, it was understandable.
Will you ever make a video about uploading larger files (in chunks maybe)?
Or that isn't a job that php and post requests can handle?
Interesting idea, I'll look into it!
This was very very very informative and helpful 👍🏾. God bless you in Jesus Mighty Name 🙏🏾
Thank you so much for your great explanation. I just have a question. You said that when the file is in the temp folder at that point the file has been uploaded to the server, so Isn't it dangerous that the file has been uploaded to the server? for exaple if the file is malicious or for instance if it's mime type has been spoofed? I mean a malicious file that is in the PHP temporary folder/memory could cause damage to the server?
Potentially, for example if someone has gained terminal access to the server, they could access the uploaded file in the temporary folder and execute it if it were a malicious executable. However most of the time files in the temporary folder just remain there until you move it to a more permanent location, or the folder is emptied by the operating system (which it does on a regular basis). It's only a risk if the server has already been compromised.
Great video Dave, thanks for al the information, I know you mentioned that going over permission is out of the scope of this video, would you have a video where do you go over these? Currently my folder is set to 755 as well as the parent, but the "if ( ! move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $destination)){" condition keeps failing ... my guess is permission, or would there be a better way to troubleshoot?
found my issue ... i displayed the directory to find out I had added an additional folder to the path ...
@@alexanderdelagarza4707 Ok great, thank you for letting me know!
Hi Dave - what are your thoughts in saving a file as binary as oppose to an image? Cab this be done in core php?
Never tried it, but it can be done it seems: stackoverflow.com/questions/35216960/php-converting-an-image-to-a-binary-file-test
Sir, Please make video tutorial on Laravel framework
Please make a video about PHP and MySQL hosting
Hi @Dave Hollingworth,
Thanks for the video , its very helpful for me. But I am facing a priblem that I cannot see the image file into my target directory and I am also not seeing any error like upload failed. I am using windows 10 and I also tried uploading by changing the permission of the target folder to allow everyone to full control,change and read. But still no luck. Can you please help me with this issue.
Try a different folder, or an absolute path to the folder you're trying to save the upload to; also check the filename and path, make sure they don't contain any invalid characters
Hi Dave, Thanks for your reply. It worked for me after trying all the steps you mentioned.Thanks a lot
Hello Dave,
How i can post my content to main page website from mysql database?
regards, thank you.
There's an example here: www.w3schools.com/php/php_mysql_select.asp
@@dave-hollingworth thanks for reply
I get it to work only on the first input. If I add two only the first one uploads if I only use the secound it will not upload.
Try printing out the entire $_FILES array to see what it contains; also check the "name" attributes are unique on the HTML input elements
Can you make a vid showing how to make sth to upload the files to a server and downloading them again?
I'm also having this problem of uploading my file into the destination directory , but i'm kinda getting an error mr dave got, someone help me please 🤯
Hi Dave,
The PHP finfo Class, did you install the package yourself?
I didn't find it in the Extensions section of my PHP.ini file.
And, sadly, when I tried to use it in my Script, I got this message:
finfo::file(application/pdf): Failed to open stream: No such file or directory
How please, may I solve this?
The extension was installed by default when I did it. Are you using an older version of PHP perhaps? The extension is called "fileinfo" - it depends on your system how to install it, try searching for that extension for your particular system. Having said that, an upgrade to the latest version of PHP might fix it, as it should be installed by default.
@@dave-hollingworth
Ah! Dave, thank you. The fileinfo extension is installed. But, I was looking for finfo! I am running PHP 8.2. Yet to upgrade to 8.3 due to PHPMyAdmin issues.
Meaning, I will seek the solution to my error elsewhere.
Again, thank you very much.
This video just says so much about how people me included don't RTFM. Thanks Anyways.
How can we view the file on website, or how can we show the content of file on website.
File can be of pdf, png or word
Just put it in a web-accessible folder, e.g images, then link to it, e.g.
@@dave-hollingworth accessing image is not a problem but how do you view text file.
For image we have img tag
Anything for files to display?
@@MewtwoStar You could link to it using an anchor tag, or just load the text into a paragraph tag directly
I'm also having this problem of uploading my file into the destination directory , but i'm kinda getting an error mr dave got, someone help me please , i remember him saying it was out of the scope of the video😰
What exactly is the error you're getting?
amazing it works for uploads tnx. but how if i want that the image is sent as attachment to my email?
If you're using PHPMailer (recommended), you can use the addAttachment method to add that file as an attachment to an email
@@dave-hollingworth can you provide me how or a tutorial link thanks so much
I have a video on how to send emails here: czcams.com/video/fIYyemqKR58/video.html
@@dave-hollingworth i just see it now. it's great but the form is without attachment and i'm using wordpress not localhost. if you have a tutorial that could help me in my case it would be great. tnx again
@@CoralShirt I'm afraid I don't use WordPress, but you should be able to adapt the code in the video to work with it
Am building a website similar to face book so I will need your email so that we can be communicating normally than just leaving comments
