[SOLVED] Array matching..

[spfoonnewb]

I have been trying to get this to work for a while now.

 

What I am trying to get this script to do is:

 

For each value in $array2, it should check $array1[VALUE-OF-ARRAY2] to see if $x (Defined elsewhere) is a match ($x would be "/", or "/main").

 

If a match is found it should output $var;

 

If a match is not found it should output "error";

 

Once it finds a match it should stop on the specific array.

Say it's on ("/", "/main", "/index"), and it matches "/main", it should not check "/index", it should exit after the match.

 

It should however return error for each of the rest of the values.

 

If there's a better way to do this let me know, I just can't seem to get it working 100% perfectly.

 

These are the arrays being used:

 

$array1 = array(
"main" => array("/", "/main", "/index"),
"me" => array("/me"),
);

 

$array2 = array("main", "me");

 

Here is the code that I was working on.

 

<?php
foreach ($array2 as $var) {
if (array_key_exists($var, $array1)) {
	foreach (array_values($array1[$var]) as $y) {
		if ($y == $x)) {
			echo $var;
			break;
		}
		else {
			echo "Error";
		}
	}
}
}
?>

What are you trying to accomplish with this? A little more detail would help greatly.

It's for a custom template system. It should set a special css style of link if it's being called, or be default if it's not being called.

 

Some of the links are "groups" so in some cases there are multiple possibilities of a highlight.

foreach($array2 as $var) {
  foreach($array1[$var] as $y) {
    if($y == $x)
      echo $var;
    else
      echo 'Error';
  }
}

That only reads the first value, and not multiple values; it prints error for any second value.

Is it not possible to make it read them all?

[chronister]

foreach($array2 as $var) {
  foreach($array1[$var] as $y) {
    if($y == $x)
      echo $var;
    else
      echo 'Error';
  }
}

 

This code should be looping through everything and comparing them. The first foreach loop takes every value in $array2, and sets it to $var. For each value it finds, it runs another foreach statement inside that and compares $array1[$var] against $x

 

so if $array2 has 5 entries, and array1 has 10 entries, it is looping 50 times to compare each of the 5 values against each of the 10 values.

 

It takes the first values of $array2 and compares it against every values of $array1[$var], then it moves to the next one and keeps going until all values in $array2 have been compared against $array1[$var]

 

Don't know if this helps or not... but it's all I got right now.

The problem was that the variable was being overwritten because it wasn't stopping after it found a match. I was able to correct it.
