Split variable using php - php

Question

I am grabbing the name attribute using jquery and passing it to my Controller via ajax call.
VIEW
<?php
$data = array(
'name' => $id.$country,
'class' => 'send',
'content' => 'Send'
);
echo form_button($data);
?>
JS
var abc = $(self).attr("name");
I would like to know if there is any codeigniter php function which can help me to separate id from country and pass them to my model.
CONTROLLER
$abc = $this->input->post('abc');
$id = first part of abc variable
$country = second part of abc variable

Answer 1

DISCLAIMER:
As #Jonast92 clarified in the comments this answer doesn't solve the solution, and i agree after re-looking at the question since the values do not actually contain a dot and are not in the form of 1.usa but rather 1usa.
Note: I'll leave the initial answer below for reference but this would only work if the characters were separated by a (.) character and not concatenated directly.
Semi-Invalid Answer:
IF the string was concatenated using a . as a separator as in:
'name' => $id . "." . $country,
You could explode that concatenated string into an array using:
$abc = explode(".",$abc);
Then the id will be stored at index 0 and country at index 1:
$id = $abc[0];
$country = $abc[1];
Just make sure that values do not contain any dot (.) characters as that would produce unwanted results.
Note: You can even limit the number of array elements using:
$abc = explode(".",$abc,2);
which will allow countries to still contain a dot without them breaking up further into an array.
Optimal Solution though would be to split those two values and pass them as seperate parameters before even posting them to the php page and only concatenate them if necessary for your application elsewhere.

Answer 2

Can you try this:
$str = $this->input->post('abc');
preg_match_all('!\d+!', $str, $matches);
print_r($matches);
EXAMPLE:
$str = '1654usa';
preg_match_all('!\d+!', $str, $matches);
print_r($matches);
To echo out the number use: echo $matches[0][0];
This will return 1654, because the regular expression searches the string for numbers, and will "pull out" all the numbers.

Answer 3

This should work for you if the id only contains numbers!
<?php
$str = '234534534Virgin Islands (U.S.)';
preg_match_all('!\d+!', $str, $matches);
$id = $matches[0][0];
preg_match_all('/((?!\d+).)*$/', $str, $matches);
$country = $matches[0][0];
echo $id . "<br />" . $country;
?>
Output:
234534534
Virgin Islands (U.S.)
