composer安装不了？

Question

1.从官网下载了Composer-Setup 文件
2.点击文件按以下步骤安装

下面是第六幅图片提示的信息
The Composer installer script was not successful [exit code 1].

OpenSSL failed with a 'certificate verify failed' error. This indicates a problem with the Certificate Authority file(s) on your system, which either cannot be found or may be out of date.

Script Output:
The "https://getcomposer.org/versions" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:
error:04091068:rsa routines:INT_RSA_VERIFY:bad signature
error:0D0C5006:asn1 encoding routines:ASN1_item_verify:EVP lib
error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
Failed to enable crypto
failed to open stream: operation failed

这个问题有谁遇到过，该如何解决。我用的是window11操作系统，php5.6.31，求帮助。
