Searching a word with a hyphen

[NLT]

OK. I have a wordlist and a few words contain a hyphen (-).

 

I'm currently using an array_search to search a string with the words from the wordlist, but I think a regular expression would be better.

 

How can I search the string with words from the wordlist the easiest and fastest with preg_match

and fastest

would be to not use regular expressions. What's your code now? I bet it's better than the equivalent preg_match() calls.

I've put them in an array and tried using array_search.

 

But say I got a word in array like "Hyphen-", and I make the word that it'll search to "Hyphen-" it'll work fine.

 

But if I use "Hyphen-Test" it won't.

Post the code you're using, and some of the data that fails when using it.

Post the code you're using, and some of the data that fails when using it.

 

$data = "Hyphen-"; // Would usually be $_POST data
// Hyphen- returns "Worked". Hyphen-Test returns "Didn't".
$blocked = array("Works", "Hyphen", "Hyphen-");
if (array_search($data, $blocked))
{
echo "Worked";
}
else echo "Didn't";

Both of these work properly:

$data = "Hyphen-Test";
$blocked = array("Works", "Hyphen", "Hyphen-Test");
if ( array_search($data, $blocked) !== FALSE ) {
echo "Worked";
} else {
echo "Didn't";
}

// *** AND ***
$data = "Hyphen-";
$blocked = array("Works", "Hyphen", "Hyphen-");
if ( array_search($data, $blocked) !== FALSE ) {
echo "Worked";
} else {
echo "Didn't";
}

 

The change to a comparison using !== FALSE is because array_search returns the array key (which could be zero) if the value is found, or FALSE if the value is not found.

 

EDIT: That change ^^^ would not affect the outcome using the data you provided, however.

But if I add something after the "Hyphen-" it returns the opposite. 

 

EDIT: I don't think I made the post clear. I need it to search the whole word for that particular phrase. Not matching the blocked word with one word on it's own if you know what I mean

The first block I posted has something after the hyphen, and it works as written.

But then if I remove the "Test" it returns the opposite. The thing is, it will be $_POST data so it could be anything. I want it to find, let's say: Hyphen- from Hyphen-Test and return it true/false. I want it to search the whole word for a blocked word and if it has it anywhere in the word return true/false.

That isn't the way you explained it to begin with. "hyphen-test" is a hyphenated word, "hyphen-" is a fragment of that word. I think this is more what you're after.

 

$data = "Hyphen-test";

$blocked = array("Works", "Hyphen", "Hyphen-");

foreach( $blocked as $v ) {

if( stripos( $data, $v) !== FALSE ) {

echo "Found!";

break;

}

}

Yeah, that is what I wanted. I tried to explain it like that in another previous post (I think). Sorry about the confusion and thanks for the help.

	echo "Found!";
	break;
}
}

 

That is what I wanted.. but I can't seem to get it to work in a function.

 

This is my current code(It returns as "no" whatever I use as $input):

function test($input)
{
$blocked = array("Works", "Hyphen", "Hyphen-");
foreach( $blocked as $v ) {
if( stripos( $input, $v) !== FALSE ) {
	echo "Found!";
	break;
 }
 else
	{
	echo "no";
	break;
	}
}
}

test("test");

Usually better to just return a value instead of echoing directly from within the function.

 

<?php
function test($input) {
$blocked = array("Works", "Hyphen", "Hyphen-");
foreach( $blocked as $v ) {
	if( stripos( $input, $v) !== FALSE ) {
		return 'Found';
	}
}
return 'Not found';
}
echo test("Hyphen"); // echoes 'Found'
echo '<br>';
echo test("not in the array"); // echoes 'Not found'
