From this string:
$input = "Some terms with spaces between";
how can I produce this array?
$output = ['Some', 'terms', 'with', 'spaces', 'between'];
You could use explode, split or preg_split.
explode uses a fixed string:
$parts = explode(' ', $string);
while split and preg_split use a regular expression:
$parts = split(' +', $string);
$parts = preg_split('/ +/', $string);
An example where the regular expression based splitting is useful:
$string = 'foo bar'; // multiple spaces
var_dump(explode(' ', $string));
var_dump(split(' +', $string));
var_dump(preg_split('/ +/', $string));
$parts = explode(" ", $str);
print_r(str_word_count("this is a sentence", 1));
Results in:
Array ( [0] => this [1] => is [2] => a [3] => sentence )
Just thought that it'd be worth mentioning that the regular expression Gumbo posted—although it will more than likely suffice for most—may not catch all cases of white-space. An example: Using the regular expression in the approved answer on the string below:
$sentence = "Hello my name is peter string splitter";
Provided me with the following output through print_r:
Array
(
[0] => Hello
[1] => my
[2] => name
[3] => is
[4] => peter
[5] => string
[6] => splitter
)
Where as, when using the following regular expression:
preg_split('/\s+/', $sentence);
Provided me with the following (desired) output:
Array
(
[0] => Hello
[1] => my
[2] => name
[3] => is
[4] => peter
[5] => string
[6] => splitter
)
Hope it helps anyone stuck at a similar hurdle and is confused as to why.
Just a question, but are you trying to make json out of the data? If so, then you might consider something like this:
return json_encode(explode(' ', $inputString));

I need to split my string input into an semicolon separate as below.
Original String: Loganathan <logu#gmail.com>; Nathan <nathan#gmail.com>; Tester <tester#gmail.com>;
I need split like
Loganathan, logu#gmail.com
Nathan, nathan#gmail.com
Tester, tester#gmail.com
How can I go about accomplishing this?
You can use explode function. explode link
$str = "Loganathan <logu#gmail.com>; Nathan <nathan#gmail.com>; Tester <tester#gmail.com>;";
$str = str_replace(array(" <",">"),array(", ",""),$str);
$converted = explode(";",$str);
print_r($converted);
Which gives you output like
Array(
[0] => Loganathan, logu#gmail.com
[1] => Nathan, nathan#gmail.com
[2] => Tester, tester#gmail.com
)
Use explode
$str = 'Loganathan <logu#gmail.com>; Nathan <nathan#gmail.com>; Tester <tester#gmail.com>;';
//Removing the "<>" symbols
$str = str_replace("<",",",$str);
$str = str_replace(">","",$str);
$result = explode(";", $str);
print_r(array_filter($result)); //Removing empty array values
Result:
Array
(
[0] => Loganathan ,logu#gmail.com
[1] => Nathan ,nathan#gmail.com
[2] => Tester ,tester#gmail.com
)
For the following code:
$string = "hello: Mister, Winterbottom";
$words = preg_split("/[\s,]+/", $string);
print_r ($words);
I get:
Array ( [0] => hello: [1] => Mister [2] => Winterbottom )
but I want the results to be:
Array ( [0] => hello [1] => Mister [2] => Winterbottom )
so that it will ignore the colon. How can I do it?
If you need to expand your character class with :, just put it inside it and use
/[\s,:]+/
See its demo here. Or, just use /\W+/ to split with 1+ non-word characters.
$words = preg_split("/[\s,:]+/", $string);
print_r ($words);
// Or
print_r(preg_split("/\W+/", $string));
See the PHP demo
$string = "hello: Mister, Winterbottom";
$words = preg_split("/[\s,]+/", $string);
$words[0] = rtrim($words[0],":");
print_r ($words);
I looked up splitting the string into array in google.I have found that str_split is working.By explode it's doesn't work in below condition.How can I split the string by explode()?
<?php
$string = "EEEE";
print_r(str_split($string));//Array ( [0] => E [1] => E [2] => E [3] => E )
print_r(explode("",$string));//Empty delimiter error
?>
As indicated by your error, explode requires a delimiter to split the string!
You should try,
$str = "EEEE";
$answer = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
alternative way would be preg_split.
for example i have sentenes like this:
$text = "word, word w.d. word!..";
I need array like this
Array
(
[0] => word
[1] => word
[2] => w.d
[3] => word".
)
I am very new for regular expression..
Here is what I tried:
function divide_a_sentence_into_words($text){
return preg_split('/(?<=[\s])(?<!f\s)\s+/ix', $text, -1, PREG_SPLIT_NO_EMPTY);
}
this
$text = "word word, w.d. word!..";
$split = preg_split("/[^\w]*([\s]+[^\w]*|$)/", $text, -1, PREG_SPLIT_NO_EMPTY);
print_r($split);
works, but i have second question i want to write list in mu regular exppression
"w.d" is special case.. for example this words is my list "w.d" , "mr.", "dr."
if i will take text:
$text = "word, dr. word w.d. word!..";
i need array:
Array (
[0] => word
[1] => dr.
[2] => word
[3] => w.d
[4] => word
)
sorry for bad english...
Using preg_split with a regex of /[^\w]*([\s]+[^\w]*|$)/ should work fine:
<?php
$text = "word word w.d. word!..";
$split = preg_split("/[^\w]*([\s]+[^\w]*|$)/", $text, -1, PREG_SPLIT_NO_EMPTY);
print_r($split);
?>
DEMO
Output:
Array
(
[0] => word
[1] => word
[2] => w.d
[3] => word
)
Use the function explode, that will split the string into an array
$words = explode(" ", $text);
use
str_word_count ( string $string [, int $format = 0 [, string $charlist ]] )
see here http://php.net/manual/en/function.str-word-count.php
it does exactly what you want. So in your case :
$myarray = str_word_count ($text,1);
I need to manage escaping in a comma split.
This is a string example:
var1,t3st,ax_1,c5\,3,last
I need this split:
var1
t3st
ax_1
c5\,3
last
Please mind this: "c5\,3" is not splitted.
I tried with this:
$expl=preg_split('#[^\\],#', $text);
But i loose the last char of each split.
use this regex
$str = 'var1,t3st,ax_1,c5\,3,last';
$expl=preg_split('#(?<!\\\),#', $str);
print_r($expl); // output Array ( [0] => var1 [1] => t3st [2] => ax_1 [3] => c5\,3 [4] => last )
working example http://codepad.viper-7.com/pWSu3S
Try with a lookbehind:
preg_split('#(?<!\\),#', $text);
Do a 3 phase approach
First replace \, with someting "unique" like \\
Do your split by ","
Replace \\ with \,
That not as nice as regex but it will work ;)
is this ok ?
<?php
$text = "var1,t3st,ax_1,c5\,3,last";
$text = str_replace("\,", "#", $text);
$xpode = explode(",", $text);
$new_text = str_replace("#", "\,", $xpode);
print_r($new_text);
?>
Output
Array ( [0] => var1 [1] => t3st [2] => ax_1 [3] => c5\,3 [4] => last )
