Attempted to call function "yaml_parse_file" from the global namespace - php

Question

I am new to Symfony, Facing problem while trying to run the cron job. I am really clueless, whats wrong here. It seems that I am trying to access some functions present in app/config/functions.php from the global namespace, But I can't figure out which namespace is it. Following is my code.
<?php
namespace App\Command;
use App\Services\Upcontent\Upcontent;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
class UpcontentRefreshCommand extends Command
{
protected static $defaultName = 'app:upcontent-refresh';
private $upcontent;
public function __construct(Upcontent $upcontent)
{
$this->upcontent = $upcontent;
parent::__construct();
}
protected function configure()
{
}
protected function execute(InputInterface $input, OutputInterface $output)
{
$output->writeln([
'',
'=================',
'Upcontent Refresh',
'=================',
'',
]);
$output->writeln('Clearing Cache...');
clear_cache();
$output->writeln('Cache Cleared');
$output->writeln('Refreshing Sports Topic...');
$output->writeln('Loading, be patient...');
$sports = $this->upcontent->getTopic('########');
$output->writeln([
'',
'=====================',
'End Upcontent Refresh',
'=====================',
'',
]);
}
}
?>
The error occur when I run, php72 bin/console app:upcontent-refresh Please help. Thanks in advance.

You will probably have to update the "autoload"-section to make sure that your custom functions.php is loaded.
{
"autoload": {
"psr-4" {
"App\\": "src/"
},
"files": ["app/config/functions.php"]
}
}
You might also want to refactor that file to instead move the functions into some kind of service-class, e.g. like this:
# src/Yaml/Parser.php
<?php
namespace App\Yaml;
class Parser
{
public function parseFile(string $fileName)
{
// The logic from your yaml_parse_file() inside your functions.php
}
}
Then in your command (or wherever you need your custom yaml parsing) inject the service:
use App\Yaml\Parser;
class MyService
{
private $yamlParser;
public function __construct(Parser $yamlParser)
{
$this->yamlParser = $yamlParser;
}
// ...
public function something()
{
$this->yamlParser->parseFile($filename);
}
}
Since Symfony provides a Yaml-component, you might even want to use that instead.
