I'm using php.
I have a text box in a form and I want to check if they have typed in a ' charactor in that field. How do i do that in php.
Thanks
if (strstr ($string_to_search, "'")!=false){
//Yup, they typed it.
}else{
//Nope, they didn't type it.
}
Note that if you're trying to comment them out, you can use
addslashes() or to remove the slashes, you can use
stripslashes() :)
aaron was nearly right... tho one error.. use this code :)
if (strstr ($string_to_search, "'")!==false){
//Yup, they typed it.
}else{
//Nope, they didn't type it.
}

P.s. junior members eh ;) :p
Hey, what was my mistake? the !== instead of !=?
Well check THIS out, mista:

:p
If I'm still wrong, please clarify. lol
i'd have to say that aarons right !== is not correct AFAIK, unless PHP has been changed
Jee may be right actually, but only if you're using the latest version of PHP :) I heard there were some changes being made and that we'll all have to get used to them, but then again I could be terribly misinformed and maybe there isn't even a new version of PHP :eek:
I need to sit down.
or just
if(strstr($string_to_search, "'")){
//Yup, they typed it.
}else{
//Nope, they didn't type it.
}
because not false is the same as true... ;)
...but being exact, the return value of strstr() isn't a boolean true either - it's only casted to true in the if-statement.
Apparently Jeewhizz confused strstr() with strpos(), because with strpos() you have to be wary of a returned 0 which gets casted to false, that's why you should use !== instead of !=.
