Bom, agora vou dar uma dica de como otimizar seu php.ini para consumir menos memória durante a execução retirando as extensões desnecessárias quando há desenvolvimento básico. Claro que, para quem desenvolve num ambiente compartilhado, a melhor maneira é manter arquivos de configurações individuais para cada conta de acesso. O Cpanel, por exemplo, permite isso, mas somente a partir do painel do WHM.

Veja o trecho de código do php.ini abaixo. Consta somente a parte das extensões:
;extension=php_apc.dll ;extension=php_apd.dll ;extension=php_bcompiler.dll ;extension=php_bitset.dll ;extension=php_blenc.dll ;extension=php_bz2.dll ;extension=php_bz2_filter.dll ;extension=php_classkit.dll ;extension=php_cpdf.dll ;extension=php_crack.dll ;extension=php_curl.dll ;extension=php_cvsclient.dll ;extension=php_db.dll ;extension=php_dba.dll ;extension=php_dbase.dll ;extension=php_dbx.dll ;extension=php_dio.dll ;extension=php_docblock.dll ;extension=php_domxml.dll ;extension=php_event.dll ;extension=php_fdf.dll ;extension=php_fileinfo.dll ;extension=php_filepro.dll ;extension=php_filter.dll ;extension=php_fribidi.dll extension=php_gd2.dll extension=php_gettext.dll ;extension=php_gmp.dll ;extension=php_gopher.dll ;extension=php_hash.dll ;extension=php_http.dll ;extension=php_hyperwave.dll ;extension=php_ibm_db2.dll ;extension=php_id3.dll ;extension=php_ifx.dll ;extension=php_iisfunc.dll ;extension=php_imagick.dll ;extension=php_imap.dll ;extension=php_ingres.dll ;extension=php_interbase.dll ;extension=php_ixsfunc.dll ;extension=php_java.dll ;extension=php_json.dll ;extension=php_ldap.dll ;extension=php_lzf.dll ;extension=php_mailparse.dll ;extension=php_maxdb.dll extension=php_mbstring.dll extension=php_exif.dll extension=php_mcrypt.dll ;extension=php_mcrypt_filter.dll ;extension=php_memcache.dll ;extension=php_mhash.dll extension=php_mime_magic.dll ;extension=php_ming.dll ;extension=php_msql.dll ;extension=php_mssql.dll extension=php_mysql.dll extension=php_mysqli.dll ;extension=php_netools.dll ;extension=php_ntuser.dll ;extension=php_oracle.dll ;extension=php_oci8.dll ;extension=php_oggvorbis.dll ;extension=php_openssl.dll ;extension=php_parsekit.dll ;extension=php_pdf.dll extension=php_pdo.dll ;extension=php_pdo_firebird.dll ;extension=php_pdo_mssql.dll extension=php_pdo_mysql.dll ;extension=php_pdo_oci.dll ;extension=php_pdo_oci8.dll ;extension=php_pdo_odbc.dll ;extension=php_pdo_sqlite.dll ;extension=php_perl.dll ;extension=php_pgsql.dll ;extension=php_phpdoc.dll ;extension=php_pop3.dll ;extension=php_printer.dll ;extension=php_pspell.dll ;extension=php_radius.dll ;extension=php_runkit.dll ;extension=php_sdo.dll ;extension=php_sdo_das_xml.dll ;extension=php_shmop.dll ;extension=php_smtp.dll ;extension=php_snmp.dll extension=php_soap.dll extension=php_sockets.dll ;extension=php_sqlite.dll ;extension=php_ssh2.dll ;extension=php_stats.dll ;extension=php_sybase_ct.dll ;extension=php_threads.dll ;extension=php_tidy.dll ;extension=php_timezonedb.dll ;extension=php_translit.dll ;extension=php_win32ps.dll ;extension=php_win32scheduler.dll ;extension=php_win32service.dll ;extension=php_win32std.dll ;extension=php_xdebug.dll ;extension=php_xmlreader.dll extension=php_xmlrpc.dll ;extension=php_xmlwriter.dll ;extension=php_xsl.dll ;extension=php_yaz.dll ; Module make problems extension=php_zip.dll ;extension=php_zlib_filter.dll ;extension=php_ps.dll ;extension=php_paradox.dll

Note que, dessas extensões instaladas, somente estas estão ativadas:
extension=php_gd2.dll extension=php_gettext.dll extension=php_mbstring.dll extension=php_exif.dll extension=php_mcrypt.dll extension=php_mime_magic.dll extension=php_mysql.dll extension=php_mysqli.dll extension=php_pdo.dll extension=php_pdo_mysql.dll extension=php_soap.dll extension=php_sockets.dll extension=php_xmlrpc.dll extension=php_zip.dll
Assim, você economiza recurso da sua máquina na execução do Apache e consegue melhorar a performance de interpretação das páginas, porque só carregou os módulos necessários.
Um abraço
Até a próxima
