note 130173 added to function.filter-var

If you need the complete filters list you can get it ; here are 3 ways ..from beginner to advanced in php scripting (the tests were on an old PHP Version 8.2.12) : for beginners: { -put this on a folder , in a file index.php -if you are using a local server what it's ON put in browser http://localhost/name of the folder you created/ <--modify that and hit the <Enter> key } START: <!doctype html> <html lang="ro"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <title>filters</title> </head> <body> <?php $i=1; foreach(get_defined_constants() as $c => $v) if( str_starts_with(strtolower($c),'filter_')){ print($i.': '.$c.'<br>'); $i++; } ?> <hr> <div style="color:red;">OR</div> <?php $i=0; foreach(get_defined_constants() as $c => $v) ( str_starts_with(strtolower($c),'filter_')) && print(++$i.': '.$c.'<br>'); ?> <hr> <div style="color:red;">OR</div> <hr> <?php $i=0; array_map(function($c){ str_starts_with(strtolower($c),'filter_') && print ++$GLOBALS['i'].': '.$c.'<br>'; },array_keys(get_defined_constants())); ?> </body> </html> :STOP If you need only the all partial results replace 'filter_' with 'FILTER_VALIDATE_' or 'FILTER_SANITIZE_' don't worry about capitalize or not i put in place strtolower .. So on EACH SECTION you'll obtain this list: 1: FILTER_FLAG_NONE 2: FILTER_REQUIRE_SCALAR 3: FILTER_REQUIRE_ARRAY 4: FILTER_FORCE_ARRAY 5: FILTER_NULL_ON_FAILURE 6: FILTER_VALIDATE_INT 7: FILTER_VALIDATE_BOOLEAN 8: FILTER_VALIDATE_BOOL 9: FILTER_VALIDATE_FLOAT 10: FILTER_VALIDATE_REGEXP 11: FILTER_VALIDATE_DOMAIN 12: FILTER_VALIDATE_URL 13: FILTER_VALIDATE_EMAIL 14: FILTER_VALIDATE_IP 15: FILTER_VALIDATE_MAC 16: FILTER_DEFAULT 17: FILTER_UNSAFE_RAW 18: FILTER_SANITIZE_STRING 19: FILTER_SANITIZE_STRIPPED 20: FILTER_SANITIZE_ENCODED 21: FILTER_SANITIZE_SPECIAL_CHARS 22: FILTER_SANITIZE_FULL_SPECIAL_CHARS 23: FILTER_SANITIZE_EMAIL 24: FILTER_SANITIZE_URL 25: FILTER_SANITIZE_NUMBER_INT 26: FILTER_SANITIZE_NUMBER_FLOAT 27: FILTER_SANITIZE_ADD_SLASHES 28: FILTER_CALLBACK 29: FILTER_FLAG_ALLOW_OCTAL 30: FILTER_FLAG_ALLOW_HEX 31: FILTER_FLAG_STRIP_LOW 32: FILTER_FLAG_STRIP_HIGH 33: FILTER_FLAG_STRIP_BACKTICK 34: FILTER_FLAG_ENCODE_LOW 35: FILTER_FLAG_ENCODE_HIGH 36: FILTER_FLAG_ENCODE_AMP 37: FILTER_FLAG_NO_ENCODE_QUOTES 38: FILTER_FLAG_EMPTY_STRING_NULL 39: FILTER_FLAG_ALLOW_FRACTION 40: FILTER_FLAG_ALLOW_THOUSAND 41: FILTER_FLAG_ALLOW_SCIENTIFIC 42: FILTER_FLAG_PATH_REQUIRED 43: FILTER_FLAG_QUERY_REQUIRED 44: FILTER_FLAG_IPV4 45: FILTER_FLAG_IPV6 46: FILTER_FLAG_NO_RES_RANGE 47: FILTER_FLAG_NO_PRIV_RANGE 48: FILTER_FLAG_GLOBAL_RANGE 49: FILTER_FLAG_HOSTNAME 50: FILTER_FLAG_EMAIL_UNICODE ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 86.125.181.164) ---- Manual Page -- https://php.net/manual/en/function.filter-var.php Edit -- https://main.php.net/note/edit/130173 Del: integrated -- https://main.php.net/note/delete/130173/integrated Del: useless -- https://main.php.net/note/delete/130173/useless Del: bad code -- https://main.php.net/note/delete/130173/bad+code Del: spam -- https://main.php.net/note/delete/130173/spam Del: non-english -- https://main.php.net/note/delete/130173/non-english Del: in docs -- https://main.php.net/note/delete/130173/in+docs Del: other reasons-- https://main.php.net/note/delete/130173 Reject -- https://main.php.net/note/reject/130173 Search -- https://main.php.net/manage/user-notes.php
