PHP preg_split string into letter pairs
I have an string looking like this:
$str = "How are you doing?";
How can I turn this string into an array looking like this:
$arr = array("Ho","w ","ar","r ","yo","u ","do","in","g?");
$array = str_split($str, 2);
Documentation.
Use str_split() function.
Take a look at str_split(); it allows you to split a string by a definable amount of characters, so your code would look like:
$arr = str_split($str, 2);
Which will split $str into an array $arr where each element contains two characters,

Insert string at specified position

How do I add - in between strings.
Let’s say for instance, I want to add - in 123456789101 at the fourth position three times thereby making it look like this : 1234-5678-9101.
Substr_replace() or str_replace has not solved the problem.
I would use combination of str_split and implode.
$code = 123456789101;
$formatted = implode('-', str_split($code, 4) );
echo $formatted; //1234-5678-9101
There are a number of ways to do this.
Use substr
$output = sprintf('%s-%s-%s', substr($string, 0,4), substr($string,4,4), substr(8,4));
Use preg_replace
$output = preg_replace('/(.{4,4})(.{4,4})(.{4,4})/', '$1-$2-$3', $string);

Split a comma-delimited string into an array?

I have a string as mention below
$string = 20181123091338,20181130070940;
Now, I want to convert this string into an array format like
$array = array("20181123091338","20181130070940");
So, How can I do this? Please help me.
Thank You
You can use explode() .
Try this
$string = "20181123091338,20181130070940";
$arr = explode(",", $string);
echo "<pre>"; print_r($arr);
Explaination
Here we are exploding string by ","(comma), so we are passing ,(comma) as first parameter in explode function and string passing as second parameter.

separate string in two by given position

I want to explode a string or an integer and separate it by a space.
E.g., I have this int 12345678, and I want its numbers to become like 123 45678. I want the first three numbers separated. Can someone give me a clue or hint in how to achieve this, like what function to use in PHP? I think using an explode will not work here because the explode function needs a separator.
You can use substr_replace() - Replace text within a portion of a string.
echo substr_replace(1234567, " ", 3, 0); // 123 4567
https://3v4l.org/9CFlX
You could use substr() :
$str = "12345678" ;
echo substr($str,0,3)." ".substr($str, 3); // "123 45678"
Also works with an integer :
$int = 12345678 ;
echo substr($int,0,3)." ".substr($int, 3); // "123 45678"
This problem will solve by using substr().
The substr() function returns a part of a string.
Syntax: substr(string,start,length)
Example:
$value = "12345678";
echo substr($value,0,3)." ".substr($value, 3);
Output: 123 45678

How to limit the elements created by explode()
(4 answers)
Closed 7 months ago.
I have a String "Hello I am apple"
I want to split to two string
str1 = "Hello"
str2 = "I am apple"
so just simply split by the first space, then the following words will be in one string
Explode function has a 3rd parameter for that:
limit
If limit is set and positive, the returned array will contain a maximum of limit elements with the last element containing the rest of string.
http://php.net/explode
list($str1, $str2) = explode(" ", $str, 2);
Same result also can be achieved by following code....
<?php
$str = "Hello I am Apple";
$str_con = explode(" ",$str,2);
echo $str_con[0];
echo $str_con[1];
?>

Php compare strings and return common values

I have two strings of keywords
$keystring1 = "tech,php,radio,love";
$keystring2 = "Mtn,huntung,php,tv,tech";
How do i do return keywords that common in both strings
You can do this:
$common = array_intersect(explode(",", $keystring1), explode(",", $keystring2));
If you want them back into strings, you can just implode it back.
Hmm, interesting question... You can use this.
$arr1 = explode(',',$keystring1);
$arr2 = explode(',',$keystring2);
$duplicates = array_intersect($arr1,$arr2);
foreach($duplicates as $word) {
echo $word;
}
You could explode() both strings on commas into arrays and loop through the first array checking to see if any of the words exist in the second array using the in_array() function. If so then add that word to a "common words" array.
Those are going to need to be arrays not variables.
$keystring1 = array('tech','php','radio','love');
$keystring2 = array('mtn','huntung','php','tv','tech');
First of all...
