Disabling xdebug when running composer

Question

When running composer diagnose, I get the following error :

The xdebug extension is loaded, this can slow down Composer a little. Disablin

Answer 1

I usually create a shell script per project, since every project has another PHP version. It's in a /bin/ directory next to composer.phar and composer.json and I run it as ./bin/composer in my project directory.

It looks like this (for php56)

#!/bin/sh
DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

COMPOSER_DISABLE_XDEBUG_WARN=1 /opt/local/bin/php56 \
    -d xdebug.remote_enable=0 -d xdebug.profiler_enable=0 \
    -d xdebug.default_enable=0 $DIR/../composer.phar "$@"

The -d options effectively disable xdebug. The COMPOSER_DISABLE_XDEBUG_WARN=1 part disables the warning composer issues.

Disabling the xdebug extension is preferred (see composer troubleshooting), but I personally like the simpler script.

Some timings on my machine: 2 Run with xdebug and ini-enabled: 1m33

Run with xdebug but ini-disabled: 0m19

Run without xdebug: 0m10
