Substring does not work ! Sigh !

[pincopallo_it]

Probably an easy question for those who know the answer

but im getting crazy to understand why a substring does not work .

I have this array called $new_array

I cycle on it and when I try to get a substring I get no result !

Has it something to do with the fact $p in this case is not a string ?

Can you help ?

Thanks

 

That is the code:

 

$lungh_array= count($new_array);

for ($contatore=0; $contatore < $lungh_array; $contatore++) {

 

if (strpos($new_array[$contatore], ':') !== false)

{

$cont = is_odd($contatore);

if($cont)

{

 

// $prova = $new_array[$contatore];

// $clean = trim($prova);

// $a = substr($clean,0,5);

// $p = $new_array[$contatore];

// $a = substr($p,0,5);

echo "Time IN " . $new_array[$contatore];

 

 

}

else

echo "Time OUT " . $new_array[$contatore];

 

 

}

}

[zenag]

can u tell me what is the value u hve gvn for $new_array

[pincopallo_it]

16:14 Casal Boccone

That is the value of an element and I need to extract the time.

Thanks

[zenag]

u need to display "Time IN 16:30" right...

[zenag]

i ve tried something like the below it works for me & it displays TIME IN: 16:14

$cont = $contatore%2; 
      if($cont)
      {
      
  
         $prova = $new_array[$contatore];
        $clean = trim($prova);
         $a = substr($clean,0,5);
        $p = $new_array[$contatore];
         $a = substr($p,0,5);
          echo "Time IN " . $a;
         
      
      }
      else{

Do all the strings you're trying to parse contain the time followed by a space? If so you can explode the string on that space and get the time string that way.

 

<?php
$str = '16:14 Casal Boccone';
list($time,$dmy) = explode(' ',$str,2);
echo str;
?>

 

Please remember to surround all code you post with

tags.

Now it s becoming a real mistery .

I tried this code and I got:

Time OUT xx

<CODE>

list($time,$dmy) = explode(' ',$new_array[$contatore],2);

echo "Time OUT " . $time . "xx";

</CODE>

if I try

<CODE>

list($time,$dmy) = explode('  ',$new_array[$contatore],2);

echo "Time OUT " . $time . "xx";

</CODE>

I got

Time OUT .... but $new_array[$contatore] is always filled.

Another idea ?
