longest array line

[mysterbx]

Hello,

 

I need to find the longest array line from the [4]th array in my curl generated array..

 

Array looks like this:

Array
(
    [0] => Array
        (
            [0] =>  Synopsis :    Jim proposes to Michelle and she accepts. Now their families are looking forward to it as is Jim's friends, Kevin and Finch. They do their best to keep Stifler from knowing but he does and all he sees is the bachelor party that goes with it. However Jim is more concerned about whether or not Michelle's parents will like him and he is also worried that he can learn how to dance before the wedding.  
   IMDB 
        )

    [1] => Array
        (
            [0] =>  Synopsis 
        )

    [2] => Array
        (
            [0] => 
        )

    [3] => Array
        (
            [0] => :
        )

    [4] => Array
        (
            [0] =>     Jim proposes to Michelle and she accepts. Now their families are looking forward to it as is Jim's friends, Kevin and Finch. They do their best to keep Stifler from knowing but he does and all he sees is the bachelor party that goes with it. However Jim is more concerned about whether or not Michelle's parents will like him and he is also worried that he can learn how to dance before the wedding.  
   IMDB 
        )

    [5] => Array
        (
            [0] => 
        )

)

 

This function should output that 0 is the longest array line ($description[4][0])

 

My code that finds the results

 

preg_match_all("#(synopsis)(\:| \:|\: | \: |)([\w\d\s\,\.\'\"]{30,999})(\n|\t|\r|)#ise", preg_replace ('@<[\/\!]*?[^<>]*?>@si',' ',html_entity_decode($r2)), $description);

 

function should print the longest array from $description[4]...

<?php
$cCount = 0;
$i = 0;
foreach($myArray as $val){
     $sLen = strlen($val);
     if($sLen > $cCount){
          $longestLine = $myArray[$i];
     }
     $i++;
}
echo "Longest Line: ".$longestLine;
?>

That won't work unless you set $count to the longest line length found so far.

Additionally, your code assumes that the array is numerically indexed.  Seeing as he's using preg_match, it always will be, but in case he needs to adapt it for something else...this should do it:

 

<?php
function longest_string($array_src) {
     $longest_key = false;
     $longest_len = 0;
     foreach ($array_src as $k=>$v)
     {
          $current_len = strlen($v);
          if ($current_len > $longest_len)
          {
               $key = $k;
               $longest_len = $current_len;
          }
     }
     return $key;
}
?>

Will return false if it finds nothing, or the key when it's found.

Right! New code:

<?php
$cCount = 0;
$i = 0;
foreach($myArray as $val){
     $sLen = strlen($val);
     if($sLen > $cCount){
          $longestLine = $myArray[$i];
          $cCount = $sLen;
     }
     $i++;
}
echo "Longest Line: ".$longestLine;
?>

Code:

$cCount = 0; $i = 0; foreach($description[4] as $val){ $sLen = strlen($val); if($sLen > $cCount){ $description = trim($description[4][$i]); $cCount = $sLen; } $i++; }
$description = explode("\n", $description);
$description = $description[0];

works with other arrays, but not with this one

[Bauer418]

Right here:

$description = trim($description[4][$i]);

You are overwriting the array that the script is looping through with a string.  Try my example posted above, seeing as it has already been coded as a function as well.

[mysterbx]

if i do this: $description = $description[$i];

 

i get no results...

 

I need to search $description[4]; for the longest array, it workds when array has only 1 result, but it doesnt work when it has more than 1....

[Bauer418]

Change the first $description in that line to something else, such as $str.  You'll also need to change references to it later on.  You're overwriting the array you want to search with the variable $description.  If that doesn't make sense, then once again, take this function:

 

<?php
function longest_string($array_src) {
     $longest_key = false;
     $longest_len = 0;
     foreach ($array_src as $k=>$v)
     {
          $current_len = strlen($v);
          if ($current_len > $longest_len)
          {
               $key = $k;
               $longest_len = $current_len;
          }
     }
     return $key;
}
?>

And call it like longest_string($description[4]) and it will return the key with the longest string.

[mysterbx]

works now...

 

i was doing this:

longest_string($description[4]);

 

but I tried:

$test = longest_string($description[4]);
echo $test;

.. and it worked...
