I see that 7.4 is now available on my app services. Unfortunatley installing redis using pecl that I need is not working on 7.4, so I am still stuck at 7.3.

More exactly, this does not work in 7.4: https://azureossd.github.io/2019/01/29/azure-app-service-linux-adding-php-extensions/

    Apologize for the late response. Yes you are correct, pecl build of redis is broken on PHP 7.4. As this issue is with PHP itself, so reaching out to PHP community would be helpful here.

    If you want redis and PHP 7.4 then refer to below work-around.

    <open SSH window>

    mkdir -p /tmp/pear/temp
    cd /tmp/pear/temp
    pecl bundle redis
    cd redis
    phpize
    ./configure --with-php-config=/usr/local/bin/php-config --enable-redis-igbinary=no --enable-redis-lzf=no --enable-redis-zstd=no
    make
    ls -l /tmp/pear/temp/redis/modules
    mkdir -p /home/site/ext
    cp /tmp/pear/temp/redis/modules/redis.so /home/site/ext/redis.so
    mkdir -p /home/site/ini
    echo "extension=/home/site/ext/redis.so" >> /home/site/ini/extensions.ini

    then add PHP_INI_SCAN_DIR app setting with a value of "/usr/local/etc/php/conf.d:/home/site/ini"

    Hope this helps.
