preg match

[Nandini]

Hi all

 

This is very good forum. I got so much solutions from this. I thank to all.

ok my problem is

i have a string like 111:[email protected]:5080/111

 

I want to know  "/" is there in my string or not. I have to write some script if "/" is there in that string.

So can any one give me preg_match to find that "/".

 

Thanq

Just use strpos().

 

$str = "111:[email protected]:5080/111";

if(strpos("/", $str)){
echo "It's in there!";
}else{
echo "Couldn't find it!";
}

Actually, that's not how you are supposed to use strpos, ProjectFear.  You need to do something like:

 

$str = "111:[email protected]:5080/111";

if(strpos("/", $str) !== FALSE){
echo "It's in there!";
}else{
echo "Couldn't find it!";
}

 

That's because if the character appears at the first position in the string, strpos() returns 0, and not FALSE, but it's still evaluated as FALSE unless you explicitly say otherwise.

I think I would side with the function strpbrk:

 

$str = "111:[email protected]:5080/111";
if(strpbrk($str, '/') == true){
   echo "It's in there!";
} else {
   echo "Couldn't find it!";
}

Yeah if I took the time to look at the big red headings in the manual that say "WARNING". Thanks for the correction.

Cheers.
