Is there any function in php that will match a word exactly and if it finds it, it returns true.

Hi,

Is there any function in php that will match a word exactly and if it
finds it, it returns true.

For example if I search for "CA"

strVar = "Bob is from Los Angeles CA" - return true

strVar "Bob is from Canada" -- returns false

Any help is appreciated

Thanks

-Ross

Thanks for your response. But if in your example
strVar "Bob is from Canada" -- would return true when I want it to
return false.

$demo="Bob is from Los Angeles CA";

$qaz=" CA"; // note the extra space

$wsx=strpos($qaz,$demo);

if ($wsx==true) {print "exact match found";}

Thats not a ideal solution to the well known php bug you refer to .

Best not to mention such things until a user has a problem IMHO .

How about "CAnada".

Faced with this sort of thing in 'C' I decided that learning to write a
regexp when I could already write C was bollocks:

You have to decide what is allowable before and after the 'CA" that
makes it a complete word, not part of something else.

In C the ispunct(), isspace() and '\0' macros proved useful.

And which well known bug is that?

using strpos, this would also match

$demo="Bob is from Los Angeles CAblahblah";

while i think OP wanted exact match. Correct me if i am wrong.

maybe something like this:

$demo="Bob is from Los Angeles CA ddfs";
$s = split(" ",$demo);
foreach ($s as $k)
{
if( $k === "CA" )
{
echo "Found CA: $k\n";
}
}

Re: Is there any function in php that will match a word exactly and if it finds it, it returns true.

This might work.

function myfunc($string,$pattern)
{
if(strpos(' '.$string.' ', ' '.$pattern.' ') !== FALSE)
{
return true;
}
return false;
}

var_dump(myfunc('Bob is from Los Angeles CA','CA'));
var_dump(myfunc('Bob is from Canada','CA'));
?>

You might use preg_match() with word boundaries... perhaps?

people shy away from regex...but, i don't know why.

/\bca(\b|$)/i

preg_match 'Bob is from Canada' returns false

preg_match 'Bill is from San Diego, CA' returns true.



you'd be hard-pressed to write anything more simple or manageable.

ummm...don't you need $wsx === true anyway?!
