PHP cURL Wrapper Functions for GET, POST, PUT, DELETE, and PATCH Requests

When integrating external APIs in PHP, using cURL can be cumbersome, so the article provides a set of reusable functions that automatically encode request data as JSON and decode JSON responses into associative arrays.

GET request

<?php
function geturl($url){
    $headerArray = array("Content-type:application/json;","Accept:application/json");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headerArray);
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output, true);
    return $output;
}

POST request

<?php
function posturl($url, $data){
    $data = json_encode($data);
    $headerArray = array("Content-type:application/json;charset='utf-8'","Accept:application/json");
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headerArray);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    $output = curl_exec($curl);
    curl_close($curl);
    return json_decode($output, true);
}

PUT request

<?php
function puturl($url, $data){
    $data = json_encode($data);
    $ch = curl_init(); // 初始化CURL句柄
    curl_setopt($ch, CURLOPT_URL, $url); // 设置请求的URL
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 将结果返回为字符串
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT"); // 设置请求方式
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data); // 设置提交的字符串
    $output = curl_exec($ch);
    curl_close($ch);
    return json_decode($output, true);
}

DELETE request

<?php
function delurl($url, $data){
    $data = json_encode($data);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output, true);
    return $output;
}

PATCH request

<?php
function patchurl($url, $data){
    $data = json_encode($data);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PATCH");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data); // 20170611修改接口，用/id的方式传递，直接写在url中了
    $output = curl_exec($ch);
    curl_close($ch);
    $output = json_decode($output);
    return $output;
}

These functions can also be encapsulated into a class for object‑oriented usage, allowing developers to call the methods directly without repeating cURL setup code.
