PHP 分割选项？ - 开卷题库

最佳答案

explode is an alternative. However, if you meant to split through a regular expression, the alternative is preg_split instead.

preg_split if you need to split by regular expressions.
str_split if you need to split by characters.
explode if you need to split by something simple.

Also for the future, if you ever want to know what PHP wants you to use if something is deprecated you can always check out the function in the manual and it will tell you alternatives.

split is deprecated since it is part of the family of functions which make use of POSIX regular expressions; that entire family is deprecated in favour of the PCRE (preg_*) functions.

If you do not need the regular expression functionality, then explode is a very good choice (and would have been recommended over split even if that were not deprecated), if on the other hand you do need to use regular expressions then the PCRE alternate is simply preg_split.

You can use the easier function preg_match instead, It's better and faster than all of the other ones.

$var = "<tag>Get this var</tag>";
preg_match("/<tag>(.*)<\/tag>/", $var , $new_var);
echo $new_var['1'];

Output: Get this var

Yes, I would use explode or you could use:

preg_split

Which is the advised method with PHP 6. preg_split Documentation

I want to clear here that preg_split(); is far away from it but explode(); can be used in similar way as split();

following is the comparison between split(); and explode(); usage

How was split() used

<?php


$date = "04/30/1973";
list($month, $day, $year) = split('[/.-]', $date);
echo $month; // foo
echo $day; // *
echo $year;


?>

How explode() can be used

<?php


$data = "04/30/1973";
list($month, $day, $year) = explode("/", $data);
echo $month; // foo
echo $day; // *
echo $year;


?>

Here is how we can use it :)

If you want to split a string into words, you can use explode() or str_word_count().

Had the same issue, but my code must work on both PHP 5 & PHP 7..

Here is my piece of code, which solved this.. Input a date in dmY format with one of delimiters "/ . -"

<?php
function DateToEN($date){
if ($date!=""){
list($d, $m, $y) = function_exists("split") ?  split("[/.-]", $date) : preg_split("/[\/\.\-]+/", $date);
return $y."-".$m."-".$d;
}else{
return false;
}
}
?>
