PHP SoapServer::handle() Method: Usage and Examples

Parses a SOAP request, invokes a registered handler and emits a SOAP response. This guide demonstrates its use in PHP code and explains when the result or side effect needs extra checks.

What It Does

Parses a SOAP request, invokes a registered handler and emits a SOAP response.

Syntax and Parameters

The examples below show a real call to SoapServer::handle with suitable arguments. Read the function call in context: its connection, handle, input data or other prerequisites are created before use.

Requirements: SOAP extension; the corresponding WSDL or service implementation.

Example 1: Core Behavior

SOAP request handling requires a correctly configured endpoint and strict access control.

<?php
class StatusService { public function health(): string { return 'ok'; } }
$server = new SoapServer(null, ['uri' => 'urn:example:service']);
$server->setClass(StatusService::class);
// handle() reads the inbound SOAP request; call only within a configured SOAP endpoint.
$server->handle();

Observe the returned value or changed resource state. A successful function call can still require additional checks before a higher-level operation is considered successful.

Example 2: Alternative or Failure Case

SOAP request handling requires a correctly configured endpoint and strict access control.

<?php
class StatusService { public function health(): string { return 'ready'; } }
$server = new SoapServer(null, ['uri' => 'urn:example:billing']);
$server->setClass(StatusService::class);
// handle() reads the inbound SOAP request; call only within a configured SOAP endpoint.
$server->handle();

Compare the different inputs, environment assumptions or result checks. Do not use a transport-level success value as proof that all business-level requirements were met.

Practical Example: Applying the Rule

SOAP request handling requires a correctly configured endpoint and strict access control.

<?php
class StatusService { public function health(): string { return 'available'; } }
$server = new SoapServer(null, ['uri' => 'urn:example:inventory']);
$server->setClass(StatusService::class);
// handle() reads the inbound SOAP request; call only within a configured SOAP endpoint.
$server->handle();

In an application, convert low-level failures into controlled responses and log only non-sensitive diagnostic context.

Important Behavior and Edge Cases

Pass trusted XML only through a correctly configured SOAP endpoint; control memory and error output.

Key Takeaways

• Parses a SOAP request, invokes a registered handler and emits a SOAP response.
• Pass trusted XML only through a correctly configured SOAP endpoint; control memory and error output.
• setClass or setObject chooses the implementation used by handle.

Select this API or pattern based on its documented behavior and the trust boundaries in your own application, and test all external integrations against their actual deployments.
