如何从Angular 4调用PHP函数

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable()
export class PhpService {
  private phpUrl = 'http://your-php-server-url'; // 替换为实际的PHP服务器URL

  constructor(private http: HttpClient) { }

  callPhpFunction(functionName: string, params: any) {
    const url = `${this.phpUrl}/your-php-script.php`; // 替换为实际的PHP脚本URL
    const body = { functionName, params };

    return this.http.post(url, body);
  }
}

import { Component } from '@angular/core';
import { PhpService } from './php.service';

@Component({
  selector: 'app-root',
  template: `
    <button (click)="callPhpFunction()">调用PHP函数</button>
    <div>{{ phpResponse }}</div>
  `,
})
export class AppComponent {
  phpResponse: string;

  constructor(private phpService: PhpService) { }

  callPhpFunction() {
    const functionName = 'yourPhpFunction'; // 替换为实际的PHP函数名
    const params = { param1: 'value1', param2: 'value2' }; // 替换为实际的参数

    this.phpService.callPhpFunction(functionName, params)
      .subscribe(response => {
        this.phpResponse = response;
      });
  }
}

<?php
function yourPhpFunction($param1, $param2) {
  // 执行你的PHP函数逻辑
  return 'PHP函数调用成功';
}

// 解析Angular发送的POST请求
$request = json_decode(file_get_contents('php://input'), true);
$functionName = $request['functionName'];
$params = $request['params'];

// 根据函数名调用相应的PHP函数
if ($functionName === 'yourPhpFunction') {
  $result = yourPhpFunction($params['param1'], $params['param2']);
  echo $result;
}
?>
