How to Split a String by Multiple Delimiters in PHP

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>';

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.

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)
)

Split String by Multiple Delimiters in PHP

PHP

$str = "a,b c,d;e f";

$pieces = preg_split('/[, ;]/', $str);

var_dump($pieces);

CodePad.

Output

array(6) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
  [3]=>
  string(1) "d"
  [4]=>
  string(1) "e"
  [5]=>
  string(1) "f"
}

How to split string on multiple delimiters keeping some delimiters?

Try this:

$src='word1&word2 !word3 word4 &word5';
$arr=explode(' ',$src=preg_replace('/(?<=[\w])([&!])/',' $1',$src));
echo join('<br>',$arr); // present the result ...

First change any occurence of a group consisting of a single character of class [&!] that is preceded by a 'word'-character into ' $1' (=itself, preceded with a blank) and then explode()the string using the blanks as separators.

If you need to deal with multiple blanks as separators between the words you could of course replace the (faster) explode(' ',...) with a slighty more "refined" preg_split('/ +/',...).

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);

Php multiple delimiters in explode

Try about using:

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

Split string into associative array by multiple delimiters

With the help of Your Common Sense and CBroe I figured it out:

$result = [];
$pattern = '/(\{\{[^}]*\}\})/';
$lines = preg_split( $pattern, $structure, null, PREG_SPLIT_DELIM_CAPTURE );
   foreach ( $lines as $line ) {
      preg_match( $pattern, $line, $matches );
      if ( $matches ) {
         $result[] = [
            'type' => 'dropdown',
            'name' => trim( str_replace( ['{{', '}}'], "", $line ) )
         ]; 
      } else {
         $result[] = [
            'type' => "text",
            'content' => trim( $line )
         ];
      }
}
