Php string exploding into a specific array

Question

Following is the String that holds the contact info. This string is dynamic i.e. sometimes new fields eg: mobile number may add up or old fields say: tel number may delete.

                              <?php $str = 
                                "tel: (123) 123-4567
                                fax : (234) 127-1234
                                email : [email protected]";
                                $newStr =  explode(':', $str);
                                echo '<pre>'; print_r($newStr); 
                              ?>

Output of the code is:

                        Array
                            (
                                [0] => tel
                                [1] =>  (123) 123-4567
                                                                fax 
                                [2] =>  (234) 127-1234
                                                                email 
                                [3] =>  [email protected]
                            )

But the output needed is in the following format:

                        Array
                            (
                                [tel] => (123) 123-4567
                                [fax] =>  (234) 127-1234            
                                [email] =>  [email protected]
                            )

I tried exploding it in may ways... but didn't work. please guide.

you are exploding with delimiter :. So between (123) 123-4567 and fax there is no separator like :. So you are getting both of them in the same value. — Pankit Kapadia

@PankitKapadia What delimiter shd i use? I didn't find any other meaningful separator. — user1871640

Is there a newline between each set of values in the text? If so, use "\n" — Anton

@user1871640 - delimiter you used is not a problem. You can use any. I just want to say that you are not getting separate values because there is no delimiter between (123) 123-4567 and fax — Pankit Kapadia

$txt = 
                            "tel: (123) 123-4567
                            fax : (234) 127-1234
                            email : [email protected]";
$arr = array();
$lines = explode("\n",$txt);
foreach($lines as $line){
    $keys = explode(":",$line);
    $key = trim($keys[0]);
    $item = trim($keys[1]);
    $arr[$key] = $item;
}
print_r($arr);

Here's a shorter way with regular expressions.

preg_match_all('/(\w+)\s*:\s*(.*)/', $str, $matches);
$newStr = array_combine($matches[1], $matches[2]);

print_r($newStr);

Results:

Array
(
    [tel] => (123) 123-4567
    [fax] => (234) 127-1234
    [email] => [email protected]
)

example here

This example assumes, however, that each data pair is on a separate line as in your provided string and that the "key" contains no spaces.

<?php
    $str = 
    "tel: (123) 123-4567
    fax : (234) 127-1234
    email : [email protected]";

$contacts = array();
$rows = explode("\n", $str);
foreach($rows as $row) {
    list($type, $val) = explode(':', $row);
    $contacts[trim($type)] = trim($val);
}
var_export($contacts);

returns

array (
  'tel' => '(123) 123-4567',
  'fax' => '(234) 127-1234',
  'email' => '[email protected]',
)

use preg_split with the delimeter ":" and "\n" (newline character):

$newStr = preg_split("\n|:", $str);

$str =
    "tel: (123) 123-4567
    fax : (234) 127-1234
    email : [email protected]";

$array = array();
foreach (preg_split('~([\r]?[\n])~', $str) as $row)
{
    $rowItems = explode(':', $row);
    if (count($rowItems) === 2)
        $array[trim($rowItems[0])] = trim($rowItems[1]);
}

You have to use preg_split because there could be different line-ending on each system. There is also possibility that the string is invalid so you should handle that (condition in the foreach cycle)

foreach( $newStr as $key=>$value){
      echo $key;
      echo $value;
}
