I have a variable defined like so: $var = "1, 2, 3"; & I have an array: $thePostIdArray = array(1, 2, 3);
The Array above works great when looping through it but when I try to use the $var in place of the comma-separated list, problems occur.
So (perfect world) it could be $thePostIdArray = array($var); which would be the same as $thePostIdArray = array(1, 2, 3);.
Every attempt so far hasn't worked :'(
Is this even possible, or is there an easier workaround?
Thank you for any pointers.

Given a long string separated with comma delimiter. The task is to split the given string with comma delimiter and store the result in an array. Use explode() or preg_split() function to split the string in php with given delimiter.
Use the String. split() method to convert a comma separated string to an array, e.g. const arr = str. split(',') . The split() method will split the string on each occurrence of a comma and will return an array containing the results.
Answer: Use the split() Method You can use the JavaScript split() method to split a string using a specific separator such as comma ( , ), space, etc. If separator is an empty string, the string is converted to an array of characters.
String with Just Commas When you want just the comma character ( , ) to appear as the separator between items in the list, use . join(",") to convert the array to a string.
Check out explode: $thePostIdArray = explode(', ', $var);

use explode function. this will solve your problem. structure of explode is like this
array explode ( string $delimiter , string $string [, int $limit ] )
now $delimiter
is the boundary string, string $string is the input string.
for 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.
If the limit parameter is negative, all components except the last -limit are returned.
If the limit parameter is zero, then this is treated as 1.
