Opentelemetry not working with php version 7.1 in laravel

[jbpal123]

I tried to integrate opentelemetry in php 7.1 project in laravel. But its not working. Can anyone provide me steps how to properly integrate opentelemetry in php 7.1 or lower version projects created using laravel?

Hello @jbpal123 , are you getting any errors when trying to use the package within your Laravel 7.1 application?

Hi @prondubuisi yes getting these errors

@prondubuisi I followed steps mentioned in below url
https://opentelemetry.io/docs/instrumentation/php/getting-started/

Note: versions of PHP prior to 7.4 are not officially supported.

It sounds like you're on a 32-bit platform: https://www.php.net/manual/en/function.hrtime.php#refsect1-function.hrtime-returnvalues (hrtime behaves differently on 32bit vs 64bit, and likely a bunch of other parts of open-telemetry as well).

Are you able to reproduce this on a currently-supported PHP version ?

Hi @bobstrecansky
I tried installing this package on php version 8.0 project build in laravel

Once i run below command:
composer require open-telemetry/opentelemetry

I get bellow error:
Problem 1
- Root composer.json requires open-telemetry/opentelemetry ^0.0.17 -> satisfiable by open-telemetry/opentelemetry[0.0.17]. - open-telemetry/opentelemetry 0.0.17 requires php-http/async-client-implementation ^1.0 -> could not be found in any version, but the following packages provide it:
- symfony/http-client Provides powerful methods to fetch HTTP resources synchronously or asynchronously
- php-http/guzzle6-adapter Guzzle 6 HTTP Adapter
- symfony/symfony The Symfony PHP framework
- php-http/curl-client PSR-18 and HTTPlug Async client with cURL
- php-http/guzzle7-adapter Guzzle 7 HTTP Adapter
- php-http/mock-client Mock HTTP client
- php-http/react-adapter React HTTP Adapter
- voku/httpful A Readable, Chainable, REST friendly, PHP HTTP Client
- swisnl/php-http-fixture-client Fixture client for PHP-HTTP
- mushroomcloud/guzzle6-adapter Guzzle 6 HTTP Adapter
- neur0toxine/pock PSR-18 compatible HTTP mock library
- netlogix/nxsentry Sentry integration
- phpgt/fetch Asynchronous HTTP client with promises.
- christophwurst/nextcloud-http-client HTTPlug and PSR7 adapter for Nextcloud
- betalabs/guzzle6-adapter Guzzle 6 HTTP Adapter
- john_zuk/php-nbp-api NBP (Narodowy Bank Polski) API client
- friendsofphp/well-known-implementations
- phpgt/curl cURL object wrapper.
- devster/http-client Symfony HttpClient component
- eslizn/polaris app framework for php
... and 8 more.
Consider requiring one of these to satisfy the php-http/async-client-implementation requirement.

Potential causes:

• A typo in the package name
• The package is not available in a stable-enough version according to your minimum-stability setting
  see https://getcomposer.org/doc/04-schema.md#minimum-stability for more details.
• It's a private package and you forgot to add a custom repository to find it

[bobstrecansky]

@jbpal123 - the async-client-implementation is explicitly left to the end user, because there are many different options and implementations may have different needs. You should be able to satisfy that requirement with one of those packages listed.

Hi All,
I have installed required dependency. Still getting error after command - php GettingStarted.php.
Now, getting below error:|

Thanks for the additional information!
The issue is that you're using 32bit PHP, and we've developed against 64bit. Is 64bit PHP an option for you? https://www.wampserver.com/en/download-wampserver-64bits/

[jbpal123]

Hi @brettmc
Thanks for the info. I have updated php from 32 bit to 64 bit. Now that issue is fixed.
But now, I am getting only bellow texts aftre running "php GettingStarted.php" command -
Starting ConsoleSpanExporter
OpenTelemetry welcomes PHP

As per the https://opentelemetry.io/docs/instrumentation/php/getting-started/ doc, I should get some json data as output.

[brettmc]

Yes, you should see some JSON data. The example works for me, so my guess is that this is a windows-specific problem, likely an output stream issue (ie, its sending the output to somewhere that's not valid in windows, or at least not visible to you).

The "ConsoleSpanExporter" attempts to write to php://stdout, I can't find any references to that being problematic on windows... Can you try swapping out the tracer provider setup for this?

$tracerProvider =  new TracerProvider(
    new SimpleSpanProcessor(
        (new \OpenTelemetry\SDK\Trace\SpanExporter\ConsoleSpanExporter(
            new \OpenTelemetry\SDK\Common\Export\Stream\StreamTransport(
                fopen('php://output', 'ab'),
                'application/json'
            )))
    )
);

This is slightly different to what the original factory code does:

• uses php://output instead of php://stdout
• does not use a stream context
