Array Search Problem

[ziycon]

I'm trying to search an array for a string and if the string exists in the array it wont go into the if statement, I'm using the below code, It just wont work for me, any ideas?

if((!in_array($string,$Array)) && ($string != '')) {
        print $string.'<br/>';
}

This is what I do, would that be practical?

 
if ( in_array ( $string, $array) ){
echo 'The ' .$string. ' is in the array';
}
else
{
echo 'The ' .$string. ' is not in the array';
}

@ziycon
translated into words:
if string is not in array and string is not empty then print string.

...exactly what has happened.

although I'd test for the string first (the second expression is not executed if the first expression evaluates to FALSE)

if ($string && in_array(...))

Basicly if the string doesn't exist in the array and the string isn't empty then it will print out but whats happening is even if the string is in the array it still prints out the string, which it shouldn't do!

[Dormilich]

can you give an example to reproduce, because that sounds unlikely?

[ziycon]

$outputArrayTemp[$outputCountTemp] has just been assigned a string.

The strings would be links like 'http://www.google.ie' etc.

if((!in_array($outputArrayTemp[$outputCountTemp],$outputArrayTemp)) && ($outputArrayTemp[$outputCountTemp] != '')) {
    print $outputArrayTemp[$outputCountTemp].'<br/>';
    $outputCountTemp++;
}

[ziycon]

Another bit of information, the links are printing out fine, the function about is basicly to stop any link being printed out twice. So say that http://www.google.ie is in $outputArrayTemp and say the link http://www.google.ie is found four times then its printing like:

http://www.google.ie
http://www.google.ie
http://www.google.ie
http://www.google.ie

When it shouldn't print out as it exists in $outputArrayTemp.

Ok, heres what I have so far, the full function. Hopefully this makes it easier to understand what I'm trying to do. Any help is much appreciated.

$linkCount = sizeof($matches[1]);
 
while($count < $linkCount) {
    $string = $matches[1][$count];
 
    if($string[0] == '/') {
        $outputArrayTemp[$outputCountTemp] = $domain.$string;
        $outputCountTemp++;
    }
    else if(substr($string,0,4) == 'http') {
        $outputArrayTemp[$outputCountTemp] = $string;
        $outputCountTemp++;
    }
 
    if((!in_array($outputArrayTemp[$outputCountTemp-1],$outputArrayTemp)) && ($outputArrayTemp[$outputCountTemp-1] != '')) {
        $outputArray[$outputCount] = $outputArrayTemp[$outputCountTemp-1];
        $outputCount++;
    }
    $count++;
}

[Dormilich]

did you define the start values of $outputCountTemp and $count anywhere?

[ziycon]

There both defined as zero, think I have it working withe the below code:

$linkCount = sizeof($matches[1]);
 
while($count < $linkCount) {
    $string = $matches[1][$count];
 
    if(($string[0] == '/') || (substr($string,0,4) == 'http')) {
        if($string[0] == '/') {
            $outputArrayTemp[$outputCountTemp] = $domain.$string;
            $outputCountTemp++;
        }
        else if(substr($string,0,4) == 'http') {
            $outputArrayTemp[$outputCountTemp] = $string;
            $outputCountTemp++;
        }
 
        if(!in_array($outputArrayTemp[$outputCountTemp-1],$outputArray)) {
            $outputArray[$outputCount] = $outputArrayTemp[$outputCountTemp-1];
            $outputCount++;
        }
    }
    $count++;
}

[Dormilich]

!in_array($outputArrayTemp[$outputCountTemp-1],$outputArrayTemp)

this will always evaluate to false

@Dormilich
I know, I fixed it, was meant to be:

!in_array($outputArrayTemp[$outputCountTemp-1],$outputArray)

That was the main problem with it not working as far as I can tell.
