PHP5.4で非互換・非推奨になった機能や関数をざっくりあぶり出すワンライナー

via. PHP: 下位互換性のない変更点 - Manual、PHP: PHP 5.4.x で推奨されなくなる機能 - Manual

PHP5.4.0RC8ということでぼちぼち正式リリースされそうなPHP5.4.0ですが、PHP5.3の時と同じような感じでざっくりざっくり書いてみました。今回のバージョンアップではPHP5.2.x→PHP5.3.xのように大きなインパクトはあまりなさそうです。
以下、$SRC_DIRは適宜設定。

find $SRC_DIR -iname \*.php -print0 | xargs -0 grep -iwE '(break|continue) +\$|get_magic_quotes_gpc|get_magic_quotes_runtime|set_magic_quotes_runtime|array_combine|(abstract|and|array()|as|break|case|catch|cfunction|class|clone|const|continue|declare|default|do|else|elseif|enddeclare|endfor|endforeach|endif|endswitch|endwhile|extends|final|for|foreach|function|global|goto|if|implements|interface|instanceof|namespace|new|old_function|or|private|protected|public|static|switch|throw|try|use|var|while|xor) +(trait|callable|insteadof)|define_syslog_variables|import_request_variables|session_is_registered|session_register|session_unregister|mysqli_bind_param|mysqli_bind_result|mysqli_client_encoding|mysqli_fetch|mysqli_param_count|mysqli_get_metadata|mysqli_send_long_data|mysqli::client_encoding|mysqli_stmt::stmt|mysql_list_dbs|mcrypt_generic_end'

Symfony Standard Edition 2.0.10のvenderディレクトリに対して実行した場合。

いくつか引っかかってますが、array_combine()の引数に空の配列を二つ指定したときの返り値がfalseではなくarray()になったことによるものです。
