Anyone know the best way to convert all the characters in a string into an array

for example

PHP Code:

$string = "this is string";



// then some how explode each character including spaces

$data = explode($string);



//so result would be something like:

$data[0] = 't';

$data[1] = 'h';

$data[2] = 'i';

$data[4] = ' ';

This should do the trick

PHP Code:

$string = "this is string";



$nr = 0;



while (isset($string{$nr})) {



    $data[$nr] = $string{$nr};

    

    $nr++;

    

}

Note that you can access the string characters also with this syntax, using [] instead of {}, anyway if you want to have array functionality you can do it in that way.

PHP Code:

$s = "this is a string";

echo $s[2];

In PHP a string is actually an array, so $foo ="hotscripts", you could access the "h" with $foo[0], the "o" with $foo[1], and so on.

I think that's done with curly braces as opposed to square brackets. So in your example: $foo{1} == "o".

Quoted from http://www.php.net/substr:

PHP Code:

<?php



// Accessing single characters in a string

// can also be achived using "curly braces"

$string = 'abcdef';

echo $string{0};                 // a

echo $string{3};                 // d

echo $string{strlen($string)-1}; // f



?>

Both [] and {} work. However, if you include the {} form in a quoted string, the results are not as expected -

PHP Code:

<?php

$string = "abcdef";

echo "The 1st char of the string is: $string[0]<br>";

echo "The 1st char of the string is: $string{0}<br>";

?>

Results in this output -
The 1st char of the string is: a
The 1st char of the string is: abcdef{0}

Ah, good point.

The 1st char of the string is: abcdef{0}

Or if you always use {} for strings, etc, then you don't have the problem:

PHP Code:

$string = "abcdef";

echo "The 1st char of the string is: $string[0]<br>";

echo "The 1st char of the string is: {$string{0}}<br>";



// plus benefits

echo "The string is: $stringg<br>";

echo "The string is: {$string}g<br>";

?>

use this

PHP Code:

$data=str_split($string); 

$data is an array
