Hi, thanks for the video.
Great explanation.
Two things to point out:
- to use curl with php, for dev (in your local PC) you need to install curl and respective php extension.
- Guzzle behind the scenes will use curl if it install, if not you should had allow_url_fopen option enable.
Thanks man. One of the best if not the best content on RUclips about APIs.
Your courses are so good and full of useful info, thanks a lot.
Thank Mr Dave.
Just the video I have been searching for.
It's just as if you made this video because of me.
Thank you
I really love your videos❤️
The way you explain and everything in details love it.👌
Thank you so much Dave, it's a great explanation, you saved my time!
Thank you ! This video just come in the right time for me !!!
Thanks sir i bought the php course and completed it
I learnt a lot
Your content are great, hope you keep posting more cause its informative specially the OOP videos. Cheers mate
Thanks a lot sir! Best regards from Mexico 👍
Thanks bro! Great translation!
Thanks for your wonderful video.
Perfect, thank you so much!
Nice video bro, thanks!
Your courses are great. One request though, could you do a video on how to make our own apis in php.
Yep, working on it!
Very thanks!!!
Thank you a lot
GRACIAS!!!! Excelent!!
Kindly consider doing a video talking more about SDKs. For example how to write them.
شكراً thank you
Awesome. Thanks
If possible please more info about advantages and disadvantages of each one.
I did cover these in the video - using file_get_contents is part of base PHP, so you don't have to install anything, but it does require that setting to be enabled in php.ini. Also, to send headers you need to separate each one with newline characters that can be prone to errors. cURL is a PHP extension, so you have to make sure it's installed, but it's easier to use than file_get_contents. Guzzle is simpler to use as it's object oriented, but it does use cURL under the hood by default, so you have to make sure cURL is installed.
@@dave-hollingworth I'm sincerely thankful.
Awesome
which one is best for Android Application
Dave, do you have any recommendations for books about the underlying logic and physics of PHP?
Not sure about books, but this article is very interesting: thephp.website/en/issue/how-does-php-engine-actually-work/
Awesome video. Please can the Guzzle be used for streaming.

Thank you for your very detailed instructions. I have a question. I want to build a search form when I enter keywords into that form and press the search button it will call to another website and then I also want to use code to perform operations like searching for something in the form of that website instead of having to go to that website to enter it manually, then also use the code to automatically click the search button (submit button) in that website (if any) and then get that search results return to my localhost website. How can I do this?
Not sure you can do that with PHP - there's a thread here that discusses it: stackoverflow.com/questions/55369863/how-can-i-use-php-to-prepopulate-a-form-on-or-send-data-to-a-3rd-party-website
First of all, thanks, your videos are great....my question: How to debug my requests? In the video the are options to see http responses only(header and body)...
I'm glad you like the videos! To properly debug requests, I recommend using an API client like Postman (www.postman.com/) or HTTPie (httpie.io/)
Can you create a Laravel course on udemy, please? Your Codeigniter course on udemy is perfect, and your voice is kinda soothing. Also, your code is well structured.
Thank you for your kind words! I'll let you know if I do! :-)
Hello, from what I understand, your function, with the file_get_content, encode.
Personally, I would like to do the opposite, I have an api but special characters such as # or - and " are not displayed, I would even say that they are not taken into account. My question is, can I use your code to do the opposite of what you do?
I'm not sure what you mean - the code in the video will call an API and display the response. If you're not seeing some characters, it could be a character encoding issue
00:05:00 - #file_get_contents(); ADVANTAGES: Part of PHP core; doesn't require extensions or external dependencies. DISADVANTAGES: Returns false for unsuccessful status request with no debugging data; Sending multiple request headers requires concatenation; Retrieving URLs requires allow_url_fopen() to be enabled which is commonly NOT enabled on "cheap shared hosting"
how do you caches the api get responses?
There are many ways to cache in PHP - some libraries here: www.google.co.uk/search?q=php+cache+library

Hi!
First of all very usefull video
Second I have a problem usign cURL, when I try to update the value of "title" I get this response
string(103) "{ "userId": 1, "id": 1, "title": "quidem molestiae enim", "{\"title\":\"Updated title\"}": "" }"
How can I solve this problem?
Thanks!
It looks like you're escaping the updated title value - what code are you using to generate that JSON?
I am trying to read file from api but neither file_get_contents nor curl are working on hosting website even if allow_url_fopen is On as shown in phpinfo.
Could be a network restriction - if the same code works locally, I would check with your hosting provider why it doesn't work there
@@dave-hollingworth on file_get_contents I'm getting failed to open stream http 451 error.
On cURL I am getting Moved 301 permanently error.
@@chromeuser7363 I've not seen 451 before - that suggests it's being blocked though: en.wikipedia.org/wiki/HTTP_451
Which a fastest library?
I haven't noticed a performance difference, but calling built-in functions will in theory be faster than using a library like Guzzle
POSTing from a.php to b.php. I save it to the database and positive/negative results are returned. How can I print this result to my a.php file?
If you want to go back to a.php, you'll need to redirect using a "Location" header. To display the data, a.php will have to read the database.
@@dave-hollingworth Then this method doesn't work for me. Actually, what I want to do is: There is 1 order panel and orders will come to this panel from different sites. The people who make the sites should not see the database connection of the panel. After the POST process, the file on the server where the panel is located is also checked. And the result of this check needs to be transmitted from the panel to the form.
How can I do it ? I couldn't find a properly working example. Very happy if you help.
@@cansahin2724 If the value isn't sensitive data, then you could just include it in the query string when you redirect. Otherwise the calling site will need to request a URL that gives them this data somehow.
@@dave-hollingworth I can't send the result back.
Im not sure why but i copied your code down from the 1:46 mark but all i got was bool(false)
What is the line of code that's causing that error?
in 9:34 i get :boolean false why
This usually happens if the hostname is unreachable (i.e. the domain name is incorrect - in the video it's "jsonplaceholder.typicode.com"
