explode()

[play_]

trying to explode a word at every character.

i couldve sworn a long time ago i've done explode('', $word). but now it says the delimiter is invalid.

So, how do i accomplish this?

 

on a side note, #php on freenode is always full and sends me to the overflow channel. does anyone know of another good channel?

<?php

$str = "test";

$str_arr = array();

for($i=0;$i<strlen($str);$i++){

$str_arr[] = substr($str,$i,1);

}

?>

Strange. i couuld've sworn it worked before.

 

but thanks jitesh

but it's echoing everything twice.

 

for example, if i echo $str_arr(2), it outputs "aa" instead of a.

 

print_r($str_arr); also echoes 2 arrays

Post your code.

you can use the curly braces after a string variable to access only one character:

 

<?php
$string = 'hello';
echo $string{0};

$length = strlen($string) - 1;
for($i = 0; $i <= $length; ++$i)
{
  echo $string{$i}.'-';
}
?>

Post your code.

 

I figured out.

the code you have me is inside a loop.

 

ill figure a way around it though.

Check with print an array.

 

<?php
$str = "test";
$str_arr = array();
for($i=0;$i<strlen($str);$i++){
   $str_arr[] = substr($str,$i,1);
}
echo "<pre>";
echo "This is the array with chars";
echo "<br>";
print_r($str_arr);
?>

tryfcode]<?php
$a = 'word';
$b = str_split($a,1);
print_r($b);
?>

An easier way:

 

<?php

$string = "hello";

$chars = preg_split('//', $string, -1, PREG_SPLIT_NO_EMPTY);

echo "<pre>" . print_r($chars, true) . "</pre>";

?>
