There is this Vue App, which uses PHP as a backend. I am incorporating Temporal PHP SDK for Workflow management. The task is simple:
Create a WorkflowClient, Start the Workflow.
But this app stops at the Creation of the WorkflowClient.
I searched and tried various solutions but there are many examples in Java and GO. I want it in PHP. Below is my PHP function that starts the workflow.
public function delete_vendor() {
cakelog::write('debug', 'delete_vendor');
$this->autoRender = false;
$id = $this->request->data['vendorId'];
cakelog::write('debug', 'vendorID: ' . $id);
// Assumes the Temporal server is running locally. Update to point to your Temporal server if not.
$workflowClient = WorkflowClient::create(ServiceClient::create('localhost:7233'));
cakelog::write('debug', 'workflowClient: ' . $workflowClient);
// Start a workflow execution.
$workflow = $workflowClient->newWorkflowStub(DeleteVendorWorkflowInterface::class);
cakelog::write('debug', 'Workflow Stub: ' . $workflow);
$run = $workflowClient->start($workflow, $id);
cakelog::write('debug', 'Workflow Runs: ' . $run);
echo "Started workflow: " . $run->getExecution()->getID();
}
WorkflowClient is not being created.
But I have checked these:
Checking Temporal Versiontemporal --version and the output was
temporal version 0.10.7 (server 1.22.2) (ui 2.21.3)
Checking the Availability of port 7233
lsof -i :7233 and the outupt was

The Temporal Web UI opens but the WorkflowClient is not being created. What may be the problem? Thanks in advance :)
There was this dependency issue of GRPC. Once I installed it. It worked like a normal execution. However, I was still struggling to adopt this framework. I hope the community and the documentation were better in a way that a Junior dev or intern could use and understand it.
