Laravel 5 with Postgres SQL - php

Question

I’m working on Laravel 5 with postgres as database. I’ve configured postgres 9.4 and pgAdmin III and these are working normally. When I try to run migrate it is giving me error:
[PDOException]
could not find driver
This is my database.php
'default' => 'pgsql',
'pgsql' => [ 'driver' => 'pgsql',
'host' => '127.0.0.1',
'database' => 'fms',
'username' => 'postgres',
'password' => 'root',
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public', ],
Initially I though, it was due to configuration of postgres on windows 7 but I tried with plain php it works perfect
<?php
$host = "host=127.0.0.1";
$port = "port=5432";
$dbname = "dbname=fms";
$db = pg_connect( "$host $port $dbname user=postgres password=root" );
if(!$db){
echo "Error : Unable to open database\n";
} else {
echo "Opened database successfully\n";
}
?>
I’ve enabled php_pgsql and php_pdo_sql in wamp as well. I’m not sure how to fix this on laravel 5.

Answer 1

As you said you already choosed Default Database as Postgres SQL
'default' => 'pgsql',
It is a must that you need to uncomment the pdo and postgres shared object in your php configuration settings (php.ini)
i.e., You need to uncomment the following lines in your php.ini
extension=pdo_pgsql.so
extension=pgsql.so
Note :
Don't forget to stop and start your apache after doing this changes (or php-fpm if using that instead).

Answer 2

I had the same problem with Laravel-WAMP-PostgreSql driver not found exception. I even successfully established direct connection to Postgre as you have, but with no luck with the "php artisan migrate" command.
After long research I found out that there are multiple php.ini files in which "extension=php_pdo_pgsql.dll" and "extension=php_pgsql.dll" are comented out.
The solution is (of course) to uncoment the extensions in the following files:
~/wamp/bin/php/php5.5.*/php.ini
~/wamp/bin/php/php5.5.*/phpForApache
~/wamp/bin/php/php5.5.*/php.ini.install
~/wamp/bin/php/php5.5.*/php.ini-development
~/wamp/bin/php/php5.5.*/php.ini-production
and
~/wamp/bin/apache/apache2.4.9/php.ini
** You can leave off the "php.ini-development" and "php.ini-production" (don't need to uncoment these files).

Answer 3

Like #jeff said, this is probably caused by not setting DB_CONNECTION=pgsql in the .env-file. The .env-file has MySQL preconfigured, so you must edit this file.

Answer 4

You have to make DB related changes in
config/database.php
.env file
and other settings in
php.ini settings
If you are still getting error, then clear cache and config
php artisan cache:clear
php artisan config:clear
It should work now!

Answer 5

Run this command to easily uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so from php.ini
sed -ri -e 's!;extension=pdo_pgsql!extension=pdo_pgsql!' $PHP_INI_DIR/php.ini
sed -ri -e 's!;extension=pgsql!extension=pgsql!' $PHP_INI_DIR/php.ini
If you do not have the drivers already installed, or it gives error like unable to load dynamic library PGSQL run this:
apt-get update && apt-get install -y libpq-dev && docker-php-ext-install pdo pgsql pdo_pgsql
This will install the pgsql and pdo_pgsql drivers.

Answer 6

you gotta modify .env file , then go to config>database.php and change the default to pgsql, and also in all your models file you need to change $protected $connection= 'pgsql'.

Answer 7

I'm using PHP7.3 and this worked for me, I forgot this:
apt-get install php7.3-pgsql
Everything runs smoothly afterwards. Just use whatever version of PHP you are using.
