Convert a String into an Array of Characters

问题:

In PHP, how do i convert:

$result = abdcef;

into an array that's:

$result[0] = a;
$result[1] = b;
$result[2] = c;
$result[3] = d;

回答1:

You will want to use str_split().

$result = str_split('abcdef');

回答2:

Don't know if you're aware of this already, but you may not need to do anything (depending on what you're trying to do).

$string = "abcdef";
echo $string[1];
//Outputs "b"

So you can access it like an array without any faffing if you just need something simple.

回答3:

$result = "abcdef";
$result = str_split($result);

There is also an optional parameter on the str_split function to split into chunks of x characters.

回答4:

You can use the str_split() function:

$value = "abcdef";
$array = str_split($value);

If you wish to divide the string into array values of different amounts you can specify the second parameter:

$array = str_split($value, 2);

The above will split your string into an array in chunks of two.

回答5:

With the help of str_split function, you will do it.

Like below::

<?php 
$result = str_split('abcdef',1);
echo "<pre>";
print_r($result);
?>

回答6:

best you should go for "str_split()", if there is need to manual Or basic programming,

    $string = "abcdef";
    $resultArr = [];
    $strLength = strlen($string);
    for ($i = 0; $i < $strLength; $i++) {
        $resultArr[$i] = $string[$i];
    }
    print_r($resultArr);

Output:

Array
(
    [0] => a
    [1] => b
    [2] => c
    [3] => d
    [4] => e
    [5] => f
)

回答7:

You can use the str_split() function

$array = str_split($string);

foreach ($array as $p){

    echo $p . "<br />";
}
