PHP Multiple Delimiters in Explode

Php multiple delimiters in explode

Try about using:

$output = preg_split('/ (@|vs) /', $input);

exploding string with multiple delimiter

Tokens all the way down...

<?php

$str   = '1-a,2-b,3-c';
$token = '-,';

if($n = strtok($str, $token))
    $array[$n] = strtok($token);
while($n = strtok($token))
    $array[$n] = strtok($token);

var_export($array);

Output:

array (
    1 => 'a',
    2 => 'b',
    3 => 'c',
  )

Or perhaps more terse without the first if...:

$array = [];
while($n = $array ? strtok($token) : strtok($str, $token))
    $array[$n] = strtok($token);

explode() on multiple delimiters

for($i=0;$i<count($lol);$i++){
    $lol[$i] = preg_split("@(\s*and\s*)?[/\s,&]+@", $lol[$i]);
}

How can I explode a string by multiple delimiters and also keep the delimiters?

This should work for you:

Just use preg_split() and set the flags to keep the delimiters. E.g.

<?php

    $string = "(2.8 , 3.1) → (↓↓2.4 , ↓3.0)";
    $arr =  preg_split("/(↑↑|↑|↓↓|↓)/", $string, -1, PREG_SPLIT_DELIM_CAPTURE);
    print_r($arr);

?>

output:

Array
(
    [0] => (2.8 , 3.1) → (
    [1] => ↓↓
    [2] => 2.4 , 
    [3] => ↓
    [4] => 3.0)
)

Can we do multiple explode statements on one line in PHP?

If you're looking to split the string with multiple delimiters, perhaps preg_split would be appropriate.

$parts = preg_split( '/(\s|&|,)/', 'This and&this and,this' );
print_r( $parts );

Which results in:

Array ( 
  [0] => This 
  [1] => and 
  [2] => this 
  [3] => and 
  [4] => this 
)

explode multiple delimiters in php

I would go for preg_split like below

<?php

$list = "{flower},{animals},{food},{people},{trees}";
$array = preg_split('/[},{]/', $list, 0, PREG_SPLIT_NO_EMPTY);
print_r($array);
?>

The output is

Array
(
    [0] => flower
    [1] => animals
    [2] => food
    [3] => people
    [4] => trees
)

How to split a string by multiple delimiters in PHP?

<?php

$pattern = '/[;,]/';

$string = "something here ; and there, oh,that's all!";

echo '<pre>', print_r( preg_split( $pattern, $string ), 1 ), '</pre>';

PHP explode string into array with space delimiter when string has multiple spaces?

You can solve your problem and simplify the code by using preg_split(). You can apply a regex including all delimiters in a character class with a quantifier and \s* to consume whitespaces around the delimiters.

Code:

$array = preg_split("/\s*[" . preg_quote(implode("", $delimiters), "/") . "]+\s*/", $str);
                      └┬┘└────────────────────────┬─────────────────────────┘└┬┘ 
      Consuming any whitespaces                   │             Consuming any whitespaces 
      around delimiter                            │             around delimiter
                                   ┌──────────────┘
                                   ├ []           → Character class with quantifier
                                   ├ implode()    → Converting array into a string
                                   └ preg_quote() → Escaping special characters

Split string with multiple delimiters

I'd use regexp like this in your case:

preg_split('/,? ?and | ?[,;] ?/', $str)

You may also want to replace spaces by \s if the other space characters may appear (like TAB, for example) or even \s* instead of ? to cover the case of multiple spaces.
