PHP从数组内的字符串元素中删除括号

Question

I am using in_array() function and trim() in order to detect strings in my array that include parenthesis (). Although that my current program is operating and meets my needs I would like to take it to the next level and make it more generic. Currently I am specifying the array position through "stack[2]".

$stack = array( "test-1" , "test-2" , "(test-3)" );

print_r($stack);

if ( in_array( "".$stack[2]."" , $stack , TRUE ) ) {
  $stack[2] = trim($stack[2], '()');
}

print_r($stack);

Before the trimming process:

Array
(
    [0] => test-1
    [1] => test-2
    [2] => (test-3)
)

After the trimming process:

Array
(
    [0] => test-1
    [1] => test-2
    [2] => test-3
)

I would like my program to search each value in the array, remove the () and save it on the same position. Sample of a test array is provided below:

$stack = array( "test-1" , "test-2" , "(test-3)" , "test-4" , "(test-5)" );

I am sure there is a way but I can not figure it how to do it.

Thank you for your time and effort.

Use a for loop and sizeof array:

$stack = array( "test-1" , "test-2" , "(test-3)" , "test-4" , "(test-5)" );

print_r($stack);

for ($i = 0; $i < sizeof($stack); $i++){
   $stack[$i] = trim($stack[$i], '()');
}

print_r($stack);
