Deprecated Functionality: when runing compile

[Andy_Acute]

Hi all

I have two Magento sites both v2.3.3

I have noticed today that I cannot run the compile function:

php -dmemory_limit=4G bin/magento setup:di:compile

I'm getting the following error:

Application code generator... 3/7 [=====>-------]  42% 18 secs 254.0 MiB
In ErrorHandler.php line 61:

  Deprecated Functionality: Array and string offset access syntax with curly
  braces is deprecated in /home/customer/www/mystagingsite.com/public_html/
  vendor/magento/framework/GraphQl/Config/Element/FieldFactory.php on line 49

I have no idea why or what has caused this.

Has anyone else experienced the same and what is the issue/solution please?

PS. I changed the curly brackets in the file from { } to [ ] on line 49 of the mentioned file but then got the following error:

Application code generator... 3/7 [=====>-------]  42% 20 secs 272.0 MiB
In ErrorHandler.php line 61:

  Deprecated Functionality: Unparenthesized `a ? b : c ?: d` is deprecated. U
  se either `(a ? b : c) ?: d` or `a ? b : (c ?: d)` in /home/customer/www/mystagingsite.com/public_html/vendor/magento/framework-message-queue/BatchC
  onsumer.php on line 154

This is so odd.

Please help if you can

Which php version you are using?

This issue arrives in php 7.4 version.

Hi Sanjay

Thank you for replying.

My hosting server automatically upgraded php to version 7.4

I have now changed this to 7.3 using their admin dashboard.

Using phpinfo.php it states the php version as 7.3.28

But I still get the compile error.

Any ideas?

Many Thanks

Andy

Hi Sanjay

Update:
My hosting company has set php 7.4 as the default so to access v 7.3 when running scripts I had to specify the php version - /usr/local/php73/bin/php-cli

Hope this helps others.

Let's say, Something like this in your code:

$str = "test";

echo ($str{0});

So please change the above code with this...

$str = "test";

echo ($str[0]);

Still, you are facing an issue please follow the below link maybe it can help you
