=== #1 A few ini_get() examples
<?php /* Our php.ini contains the following settings: display_errors = On register_globals = Off post_max_size = 8M */ echo 'display_errors = ' . ini_get('display_errors') . "\n"; echo 'register_globals = ' . ini_get('register_globals') . "\n"; echo 'post_max_size = ' . ini_get('post_max_size') . "\n"; echo 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "\n"; echo 'post_max_size in bytes = ' . return_bytes(ini_get('post_max_size')); function return_bytes($val) { $val = trim($val); $last = strtolower($val[strlen($val)=== ==Anmerkungen== Hinweis: '''When querying boolean values'''<br /> A boolean ini value of ''off'' will be returned as an empty string or "0" while a boolean ini value of ''on'' will be returned as "1". The function can also return the literal string of INI value. <br /> Hinweis: '''When querying memory size values'''<br /> Many ini memory size values, such as [[ini.sect.file-uploads.php#ini.upload-max-filesize|upload_max_filesize]], are stored in the php.ini file in shorthand notation. '''ini_get()''' will return the exact string stored in the php.ini file and NOT its [[language.types.integer|integer]] equivalent. Attempting normal arithmetic functions on these values will not have otherwise expected results. The example above shows one way to convert shorthand notation into bytes, much like how the PHP source does it. <br /> ==Siehe auch== * [[function.get-cfg-var|get_cfg_var()]] * [[function.ini-get-all|ini_get_all()]] * [[function.ini-restore|ini_restore()]] * [[function.ini-set|ini_set()]] [[Kategorie:PHP 4|I]] [[Kategorie:PHP 5|I]] [[Kategorie:PHP Options/Info Funktionen|I]]
