Apr 01, 2025 am 09:48 AM"_parseFeaturesHeaderFile()" error and solution for PECL installation extension in Docker environment
When installing PHP extensions using PECL in Docker, you may encounter Call to undefined function _parseFeaturesHeaderFile()
error. This article analyzes the cause of the error and provides a solution.
error message:
<code>fatal error: uncaught error: call to undefined function _parsefeaturesheaderfile() in /usr/local/lib/php/os/guess.php:248</code>
Problem analysis: This error usually originates from the PHP version related development packages that do not match the PHP version. The error message points to /usr/local/lib/php/os/guess.php
, indicating that the problem is related to the configuration of the PHP environment.
Dockerfile example (problem code):
FROM php:7.3-fpm-alpine # ...Other configurations... RUN apk add --no-cache --virtual .build-deps autoconf automake make g gcc libtool dpkg-dev dpkg unzip \ curl pkgconf file re2c pcre-dev php7-pear php7-dev openssl-dev graphviz \ # ...Other configurations...
The root cause of the problem: php7-pear
and php7-dev
are used in the Dockerfile, but the basic image is php:7.3-fpm-alpine
, which causes PEAR and PHP development package versions to be incompatible with PHP 7.3.
Solution: Replace php7-pear
and php7-dev
with package names php7.3-pear
and php7.3-dev
that match the PHP version 7.3.
Modified Dockerfile snippet:
RUN apk add --no-cache --virtual .build-deps autoconf automake make g gcc libtool dpkg-dev dpkg unzip \ curl pkgconf file re2c pcre-dev php7.3-pear php7.3-dev openssl-dev graphviz \ # ...Other configurations...
Through this modification, we ensure that all PHP-related development packages are compatible with PHP version 7.3, thus resolving the error of _parseFeaturesHeaderFile()
function. After modification, rebuild the Docker image and try to install the extension. If the problem persists, check for other possible conflicts or dependency issues.
