如何解决JS + PHP + Apache环境下无法上传48MB以上文件的问题？

function videoFileUpload() {
    //每片切片1MB
    const LENGTH = 1024 * 1024;
    let start = 0;
    let end = start + LENGTH;
    let blob_num = 1;
    let is_stop = 0;
    let timer; // 声明计时器变量

    this.start = () => {
        const file = files.files[0];
        uploadSlice(file);
    };

    this.stop = () => {
        is_stop = 1;
        clearTimeout(timer); // 清除计时器
    };

    const uploadSlice = (file) => {
        if (is_stop || start >= file.size) return;
        const blob = file.slice(start, end);
        start = end;
        end = start + LENGTH;

        const xhr = new XMLHttpRequest();
        const formData = new FormData();
        const total_blob_num = Math.ceil(file.size / LENGTH);

        formData.append('file', blob);
        formData.append('blob_num', blob_num++);
        formData.append('total_blob_num', total_blob_num);
        formData.append('file_name', file.name);

        xhr.open('POST', '/upload.php', false);
        xhr.onload = () => {
            timer = setTimeout(uploadSlice, 1000, file); // 递归调用上传下一个切片
        };
        xhr.onerror = (error) => {
            console.error("上传失败:", error);
            clearTimeout(timer); // 上传失败，清除计时器
        };
        xhr.send(formData);
    };
}
