I want to get the value of an array type given a certain index. The array's values are
$status = [1,2];
And I used these code to get the value:
$task_state = $status[1];
But it actually thought $status is a string and returns
'['
I know that this is actually quite simple, but I just can't seem to find the answer to my problem. Thank you
If $status defined as a string, you can return php value of it with eval function like below:
$status = '[1,2]';
$status_array = eval('return ' . $status . ';');
$task_state = $status_array[0];
Caution The eval() language construct is very dangerous because it allows execution of arbitrary PHP code. Its use thus is discouraged. If you have carefully verified that there is no other option than to use this construct, pay special attention not to pass any user provided data into it without properly validating it beforehand.
i try to copy your script and here what i get
$status = [1,2];
$task_state = $status[1];
var_dump($status);
exit;
the result is :
array(2) { [0]=> int(1) 1=> int(2) }
can you give me line of your code for displaying '['. may be your php version is the problem. See refrence.
array(1, 2) instead [1, 2]Maybe you are saying that the values of your array:
$status = array(1,2);
So to get a value from the array:
echo $tatus[0] . "and " . $tatus[1];
output:
1 and 2
$status = array();like this.[]to define arrays is only supported in PHP >= 5.4
