Hi all!

 

How can I get the result of $c out of this function? I know the code is odd looking but it does mean something I just need result $c.

 

Thanks!

 

<?php

$extensions_file = (file("extensions_additional.conf"));

function search_array($value)

{

$a = "exten => 56201,n,GotoIf(\$[x\${PIN} = x";

$b = substr($value,0,37);

if ($a == $b)

{

$c = 56201;

return ($c);

}

}

#array_walk($extensions_file,"search_array");

echo ($c);

?>

Could you try calling the function within an echo..

 

Try

<? echo search_array($value); ?>

 

Ensuring you pass the value of $value where $value is within the call.. whether this is within a POST variable or otherwise.

[MetalSmith]

That is not working either.

Maybe you have an extra set of parens in line 2 and unmatched parens in line 5?

The string comparison does work becuase if I put echo $c; after $c = 56201; I see 56201 on my screen. So for some reason I am not extracting the result $c out of that function correctly.

[George Botley]

I don't understand why this isn't working for you, but when I write functions I return a value without any brackets.... Could this be why? - I wouldn't know as I don't write functions with brackets, I write them echoing values that I then call in later.

I simplified things for testing. Where am I going wrong with getting $c out of this function?

 

It keeps returning the number 1

 

$x = array("a"=>"Dog","b"=>"Cat","c"=>"Horse");

 

function search_array($value)

 

{

 

$a = "Horse";

$b = substr($value,0,5);

 

if ($a == $b)

 

{

 

$c = 56201;

echo ($c);

return ($c);

 

}

 

}

 

$d = array_walk($x,"search_array");

 

echo ($d);

<?

$x = array("a"=>"Dog","b"=>"Cat","c"=>"Horse");

function search_array($value)

{

$a = "Horse";
$b = "Horse";

if ($a == $b) {
   $c = 56201;
   return $c;
}

}

$d = array_walk($x,"search_array");

echo "$d";
$return = search_array($value);
echo "$return";

?>

 

Take a look a that adaptation,

 

I have tweaked a few things for testing purposes, removed all brackets over echos and returns...

 

Re-add your substr strings back in to this new code and see if it still works, you have to ensure you are setting the value of $value in your script somewhere.

[MetalSmith]

Well that is not giving me what I want either lol. All I want is to walk through each array value and compare the value with a string. If they are equal then give me a result.

 

Maybe the array_walk is not the right choice. Functions are hard to understand for me for some reason.

[George Botley]

Sorry for not being of help, I neglected to understand the issue being with the walk function. I can't help you there i'm afraid as I have not used this function in the past.

[MetalSmith]

Ok I used you code and got it to work with replacing $value with $d

 

Is $return a global variable? Hows does $return spit out $c?

 

$x = array("a"=>"Dog","b"=>"Cat","c"=>"Horse");

 

function search_array($value)

 

{

 

$a = "Horse";

$b = "Horse";

 

if ($a == $b) {

  $c = 56201;

  return $c;

}

 

}

 

$d = array_walk($x,"search_array");

 

$return = search_array($d);

echo "$return";
