Php > Arrays

Converts a string to an array. If the optional $num parameter is specified

Converts a string to an array. If the optional $num parameter is specified
, the returned array will be broken down into chunks with each being split in $num length. 

This fuction is almost the same as the fuction str_split included in php5. 


<?php 
function strsplt($thetext,$num) 
{ 
if (!$num) 
{ 
$num=1; 
} 
$arr=array(); 
$x=floor(strlen($thetext)/$num); 
while ($i<=$x) 
{ 
$y=substr($thetext,$j,$num); 
if ($y) 
{ 
array_push($arr,$y); 
} 
$i++; 
$j=$j+$num; 
} 
return $arr; 
} 
?> 
<?php 

$str = "Hello Friend"; 

$arr1 = strsplt($str,1); 
$arr2 = strsplt($str, 3); 

print_r($arr1); 
print_r($arr2); 

?> 


Output may look like: 

Array 
( 
    [0] => H 
    [1] => e 
    [2] => l 
    [3] => l 
    [4] => o 
    [5] => 
    [6] => F 
    [7] => r 
    [8] => i 
    [9] => e 
    [10] => n 
    [11] => d 
) 

Array 
( 
    [0] => Hel 
    [1] => lo 
    [2] => Fri 
    [3] => end 
)
