note 77512 added to function.str-replace

Some controls problems when you want to replace backslashes '\' ? Look this example and the protected functions (we try to replace '\' by '.') : <?php //****** test with bad double-quote parameter test_replace_backslash("abcde\2fghij","."); //****** echo "\n"; //****** test with good simple-quote parameter test_replace_backslash('abcde\2fghij',"."); //************************************** //************ functions **************** function test_replace_backslash($str_test,$str_replace) { $str_new= replace_backslash($str_test,"."); if (!$str_new) echo "no readable char found - control call with 'string' and not ".'"'."string".'"'; else echo $str_new; } //***** function replace_backslash($str_to_detect,$str_replace) { if(chrs_is_all_readable($str_to_detect)) { return(preg_replace('[\\\]',$str_replace,$str_to_detect)); } return (false); } //***** inspired from http://fr.php.net/manual/fr/function.chr.php#70931 //***** ( thank to "jgraef at users dot sf dot net") function chrs_is_all_readable($string) { for ($i=0;$i<strlen($string);$i++) { $chr = $string{$i}; $ord = ord($chr); if ($ord<32 or $ord>126) return(false); } return (true); } ?> this example return : no readable char found - control call with 'string' and not "string" abcde.2fghij ---- Server IP: 217.174.196.197 Probable Submitter: 82.242.125.194 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/77512 Del: integrated -- https://master.php.net/note/delete/77512/integrated Del: useless -- https://master.php.net/note/delete/77512/useless Del: bad code -- https://master.php.net/note/delete/77512/bad+code Del: spam -- https://master.php.net/note/delete/77512/spam Del: non-english -- https://master.php.net/note/delete/77512/non-english Del: in docs -- https://master.php.net/note/delete/77512/in+docs Del: other reasons-- https://master.php.net/note/delete/77512 Reject -- https://master.php.net/note/reject/77512 Search -- https://master.php.net/manage/user-notes.php
