Explode and then merge arrays - php

Question

I have two strings, one containing names separated by commas and the other containing email addresses separated by commas.
I now want my end result to replicate the behaviour as if I had gotten those values from the database with a:
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
echo $row['name'].'<br />'.$row['email'];
}
So I have for example these strings:
email1#domain.com,email2#domain.com,email3#domain.com
and
name1,name2,name3
And can then explode these into value arrays. Now, after exploding them,
I want to be able to make a loop where in each loop I can get $name[0] and $email[0] together, and $name[1] and $email[1] together, etc.
How can I merge the two arrays (after exploding them) and get the data for each datapair (name and email) in a loop?

Answer 1

So if I understood you right, you are converting your strings (lets call them email, and name) too two arrays (lets call them arrEmail, and arrName) and now you want to get a array with the merged datasets.(creating the arrays should be easy if not check this out: manual for php explode function)
If so I would create a for loop based on the length of your two arrays. In the loop I would extract value i of arrEmail and arrName, and put the information into an two-dimensional array. Maybe something like this:
It should work but I didn't test it for ages so if not leave me a comment.
<?php
$arrEmail = array();
$arrName = array();
$arrGoal;
$arrLength = count($arrName);
//creating two-dimensional Array
for($i = 0; $i < $arrLength; $i++){
$arrGoal[$i] = array($arrName[$i], $arrEmail[$i]);
//should look something like this ((name, email),(name, email)…)
}
$arrGoalLength = count($arrGoal);
//accessing Array
//1. dimension
for($i = 0; $i < $arrGoalLength; $i++){
//2. dimension
//Variables should be global (but aren't)
$newName = $arrGoal[$i][0];
$newEmail = $arrGoal[$i][1];
}
?>

I think you want something like this:
$output = array();
for ($i = 0; $i < count($names); $i++) {
$output[] = $names[$i] . ' ' . $emails[$i];
}
print_R($output);

Answer 3

$emails = 'email1#domain.com,email2#domain.com,email3#domain.com';
$emails = explode(',', $emails);
$names = 'name1,name2,name3';
$names = explode(',', $names);
and you can use array_combine() as follow :
$combined = array_combine($names, $emails);
foreach($combined as $name => $email){
echo $name, ' : ', $email, '<br/>';
}

Answer 4

I think you should use the built in explode function wich will allow you to turn a string to an array by spliting it using a delimiter (comma) :
$names = explode(",",$row['name']);
$email = explode(",",$row['email']);
for merging them you should use something like this
$Array = array();
for ($j = 0; $j < count($names); $j++) {
$Array[] = [$names[$j],$email[$j]];
}

Answer 5

This is kind a related with your question, but only if you like to access the value by a key(e.g. access the name by email provided):
<?php
$emails = 'email1#gmail.com,email2#gmail.com,email3#gmail.com';
$names = 'name1,name2,name3';
$arrayEmails = explode(',',$emails);
$arrayNames = explode(',',$names);
$result = array_combine( $arrayEmails, $arrayNames);
print_r($result);
?>
