[SOLVED] Only echo 1 if

[newbtophp]

I have alot of if statements to the variable $file.

 

How can i only echo 1 if, instead of more (if more then one if statement matches $file)?

What do you mean? Can you show some code?

[newbtophp]

<?php

$file = "hello, I have a pet goat, i know its random, but who cares?";

if(preg_match('/goat/', $file)) {

echo "it contains goat fool!";

}

if(preg_match('/hello/', $file)) {

echo "it contains hello!";

}

if(preg_match('/random/', $file)) {

echo "it contains random!";

}

?>

 

 

It would echo all of them, how would i only allow it to echo the first match (like in this case 'hello')

You could change the echos to die()'s, but this might not be practical if you have more code that will execute:

 

$file = "hello, I have a pet goat, i know its random, but who cares?";

if(preg_match('/goat'/, $file)) {

die("it contains goat fool!");

}

if(preg_match('/hello'/, $file)) {

die("it contains hello!");

}

if(preg_match('/random'/, $file)) {

die("it contains random!");

}

 

 

If you need to execute more code, you can make it into a function for parsing the file:

 

function parseFile($file)
{
if(preg_match('/goat'/, $file)) {

echo "it contains goat fool!";
return;
}

if(preg_match('/hello'/, $file)) {

echo "it contains hello!";
return;
}

if(preg_match('/random'/, $file)) {

echo "it contains random!";
return;

}
}

 

Then just call that function somewhere in your code.

 

Or you could use else if:

 

<?php

$file = "hello, I have a pet goat, i know its random, but who cares?";

if(preg_match('/goat/', $file)) {

echo "it contains goat fool!";

}

else if(preg_match('/hello/', $file)) {

echo "it contains hello!";

}

else if(preg_match('/random/', $file)) {

echo "it contains random!";

}

?>

You're not matching any patterns, no need for preg_match():

 

<?php
$file = "hello, I have a pet goat, i know its random, but who cares?";
$words = Array('goat', 'hello', 'random');
foreach($words as $word)
if(strpos($file, $word) !== false)
	echo 'Found ' . $word . '<br />';
?>

Oh sorry, I didn't realize that you wanted only one to echo.. Just add a break to my previous example (I can't edit it):

 

<?php
$file = "hello, I have a pet goat, i know its random, but who cares?";
$words = Array('goat', 'hello', 'random');
foreach($words as $word)
if(strpos($file, $word) !== false)
{
	echo 'Found ' . $word . '<br />';
	break;
}
?>

Thanks both of you, both are great!
