[SOLVED] strstr help

[dennismonsewicz]

I have the following code:

 

$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

$arr = array("dog", "cat");

foreach($arr as $key) {
	$find = strstr($url, $key);
}
echo $find;

 

it isn't working... any suggestions?

$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
   
   $arr = array("dog", "cat");
   
   foreach($arr as $key => $val) {
      $find = strstr($url, $key);
   }
echo $find;

gevans made the fix, but you do realize you're overwriting $find if it finds 'dog' anyway, right? Try this:

 

$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

$arr = array("dog", "cat");
$find = '';

foreach($arr as $key =>) {
	$find = strstr($url, $key);
                          echo $find;
}

 

[dennismonsewicz]

still nothing

[Zhadus]

If you used mine instead of his, I'm an idiot

 

$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

$arr = array("dog", "cat");
$find = '';

foreach($arr as $key => $val) {
	$find = strstr($url, $val);
                          echo $find;
}

 

Also, what exactly are you expecting and what are you getting?

[dennismonsewicz]

that still didn't work...

 

I am trying to search the URL for a particular value and then I am going to create a switch.

You have to be more specific. Define not working and what you want to do. We are not psychic.

[dennismonsewicz]

sorry guys... It is not echoing out the $find. And if I echo out $key then I get the last variable in the array.

 

so if dog and cat are in the array and then I echo out $key, I get cat.

 

I need for this script to search through the URL I am grabbing for each of the values in the array. If it finds one then it will be set to a variable that I will then use to pass into my switch. I am just running some dummy code now to get the foreach statement working...

 

Did any of that make sense? Sorry if it didn't... if you are still confused I will try to explain in more detail

 

updated code

 

<?php	$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

$arr = array("dog", "cat");
$find = '';

foreach($arr as $key => $val) {
	$find = strstr($url, $val);
}
?>

<p><?php echo $find; ?></p>

 

[Ken2k7]

So you're trying to find if the $url contains a string in $arr? Is that it?

[dennismonsewicz]

yes

[Ken2k7]

<?php   $url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
   
   $arr = array("dog", "cat");
   $find = -1;
   
   foreach($arr as $key => $val) {
      $pos = strpos($url, $val);
      if ($pos !== false) $find = $pos;
   }
?>

<p><?php echo $find > -1? $arr[$pos] : 'not found'; ?></p>

Like that?

[dennismonsewicz]

wow that worked perfectly lol...

 

can you explain your code versus mine?

[dennismonsewicz]

your code works on one page but not on a another

 

so if I have the url of

 

http://localhost/cat/page.php (and then evaluate the url using the code it does not work)

 

but if i have

 

http://localhost/dog/page.php (it works)

 

so its like its only finding the first variable in the array

[dennismonsewicz]

ok so I have changed the code up a little bit

 

$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
   
   $arr = array("dog", "cat");
   $find = count($arr);
   
   for($i > 0; $i > $find; $i++) {
   		$find = strstr($url, $arr[$i]);
   }

echo '<p>' . $find . '</p>';

 

it echoes out the actual numbered position of the value in the array (EX: cat equates to position 2; dog equates to position 1)

[dennismonsewicz]

ok so I am completely lost and am racking the hell out of my brain... any suggestions?

[dennismonsewicz]

changed my code yet again:

 

$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
   
   $arr = array("dog", "cat");
   
   $explode = explode("/", $url);
   
   foreach($arr as $val){
   	if(in_array($val, $explode)) {
   		$find = $val;
   	} else {
   		$find = "NOPE!";
   	}
   }

 

if in the url cat is found and cat happens to be last in the array then it works... but if cat is in the url but is first in the array then it does not work
