Php filters special characters such as Slashes

: This article mainly introduces php filter slash and other special characters. if you are interested in the PHP Tutorial, please refer to it. Zookeeper

$ ArrFilters = array ("'", "<", ">", "\ x {5c }");

Function IsExistStrings ($ SrcString, $ ArrFilters ){
Foreach ($ ArrFilters as $ key => $ value ){
If (@ preg_match ("/$ value/", $ SrcString )){
Return true;
}
}
Return false;
}

You only need to put the string to be filtered in the $ ArrFilters array. some special characters cannot be expressed or escaped characters, then, you need to enter the ASCII code input method, such as "\ x {5c}" in the array $ ArrFilters, where "5c" is the ASCII code of the slash, and other characters are the same! Unicode codes are also supported.
