Well, the good news is that PHP 7.3.18RC1 and 7.4.6RC1 already
ship with OpenSSL 1.1.1g, so the immediate problem is solved.

The bad news is that there may indeed be an issue with our OpenSSL
usage.

I Just want to add something.I did this with normal php and it worked fine but with the php laravel framework it gives me the same error.
My php version 7.4.5,OS Win10 Pro 2019 in laravel 6.

Olá. Estou tendo o mesmo problema que o huzaifarasheen900 informou.

linha de teste: 

$var = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=" . SECRET_KEY . "&response={$SecretKey}");

Resultado:
Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14095126:SSL routines:ssl3_read_n:unexpected eof while reading in D:\Projetos\Paginas de Teste\ClassCaptcha.php on line 14

Thanks.  This issue is resolved as of PHP 7.4.6.

This will still need to be fixed for OpenSSL 3.0 so re-opening and removing OS

php master as of today:

    Merge branch 'PHP-8.1'

build simplest way possible

./configure --prefix=$HOME/test/php-test --with-openssl
make
make install

with

OpenSSL 3.0.2 15 Mar 2022 (Library: OpenSSL 3.0.2 15 Mar 2022)
linux distro, glibc 2.35

and

php-test]$ ./bin/php ~/ssl-test1.php

Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages:
error:0A000126:SSL routines::unexpected eof while reading in /home/users/arekm/ssl-test1.php on line 4

$ cat /home/users/arekm/ssl-test1.php
<?php

$recaptcha_url = 'https://   www.    google.    com/recaptcha/api/siteverify'; // remove spaces
file_get_contents($recaptcha_url);

Is there a temporary workaround for this on php 8.1.2 or when could we expect the patch to be shipped?

I had the same error with php8.0 after updating Ubuntu to 22.04 (which upgrades OpenSSL to 3.0).

Running `sudo apt install php8.0-curl` the issue disappeared.

I got rid of the error message by modifying openssl.cnf as described here:

https://gist.github.com/rdh27785

My setup: Ubuntu Server 22.04 LTS, apache2, php8.1

After upgrading my CentOS to Stream 9 and installing PHP 8.1.x I started receiving the warning message below:

Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:0A000126:SSL routines::unexpected eof while reading in /test.php on line 5

I changed the file "/etc/ssl/openssl.cnf" (as other people suggested), enabling legacy, but the warning message still shows up (even after rebooting the server). Some people had success with this change but all of them were on Ubuntu. I didnt find any person using CentOS that managed to make the warning disappear changing the openssl.cnf file.!

My openssl version is below:

[root@localhost ~]# openssl version
OpenSSL 3.0.1 14 Dec 2021 (Library: OpenSSL 3.0.1 14 Dec 2021)


My openssl.cnf file is below (the changes proposed to this file in order to prevent the warning were not done below, I am pasting you the original file contents):

#
# OpenSSL example configuration file.
# See doc/man5/config.pod for more info.
#
# This is mostly being used for generation of certificate requests,
# but may be used for auto loading of providers

# Note that you can include other files from the main configuration
# file using the .include directive.
#.include filename

# This definition stops the following lines choking if HOME isn't
# defined.
HOME			= .

 # Use this in order to automatically load providers.
openssl_conf = openssl_init

# Comment out the next line to ignore configuration errors
config_diagnostics = 1

# Extra OBJECT IDENTIFIER info:
# oid_file       = $ENV::HOME/.oid
oid_section = new_oids

# To use this configuration file with the "-extfile" option of the
# "openssl x509" utility, name here the section containing the
# X.509v3 extensions to use:
# extensions		=
# (Alternatively, use a configuration file that has only
# X.509v3 extensions in its main [= default] section.)

[ new_oids ]
# We can add new OIDs in here for use by 'ca', 'req' and 'ts'.
# Add a simple OID like this:
# testoid1=1.2.3.4
# Or use config file substitution like this:
# testoid2=${testoid1}.5.6

# Policies used by the TSA examples.
tsa_policy1 = 1.2.3.4.1
tsa_policy2 = 1.2.3.4.5.6
tsa_policy3 = 1.2.3.4.5.7

[openssl_init]
providers = provider_sect
# Load default TLS policy configuration
ssl_conf = ssl_module

# Uncomment the sections that start with ## below to enable the legacy provider.
# Loading the legacy provider enables support for the following algorithms:
# Hashing Algorithms / Message Digests: MD2, MD4, MDC2, WHIRLPOOL, RIPEMD160
# Symmetric Ciphers: Blowfish, CAST, DES, IDEA, RC2, RC4,RC5, SEED
# Key Derivation Function (KDF): PBKDF1
# In general it is not recommended to use the above mentioned algorithms for
# security critical operations, as they are cryptographically weak or vulnerable
# to side-channel attacks and as such have been deprecated.

[provider_sect]
default = default_sect
##legacy = legacy_sect

[default_sect]
activate = 1

##[legacy_sect]
##activate = 1

I gave up providing you the contents of my openssl.cnf file... php.net blocked me everytime I pasted the content of the file, saying there are links not allowed... anyway, if you want the file I can provide you by mail.
