I have this code
<?php
$numbers = "'10', '20', '30'";
$the_array = array($numbers);
$match = "20";
if (in_array($match, $the_array)) echo "OK";
?>
But it's not working, so how can I define the $numbers or the $the_array in order for this to work? If I echo the $numbers it shows:
'10', '20', '30'
And if I put that like this:
$the_array = array('10', '20', '30');
It works, but it's not working the way it's in the above code.
Thanks in advance.
You can do it for example with:
$numbers = "'10', '20', '30'";
$the_array = explode("'", $numbers);
$match = "20";
if (in_array($match, $the_array)) echo "OK";
or with:
$numbers = "'10', '20', '30'";
$the_array = str_getcsv($numbers, "'");
$match = "20";
if (in_array($match, $the_array)) echo "OK";
When you are initializing $numbers, you are not initializing it an array with three values, but rather as a string. For example, if you initialized it like this:
$numbers = "There are '12' inches in a foot";
And you echo it, you will get:
There are '12' inches in a foot
That is because a string is echoed. This is what you did. Instead, initialize $numbers as an array. If you want the elements of the array to be numbers, do this:
$numbers = array(10, 20, 30);
If you want them to be strings, do this:
$numbers = array('10', '20', '30');
