从数组中替换字符串

Question

Currently I have an array

$cop_row = array('first_pulse1', 'second_pulse2');

what I want is to replace first_ & second_ from the cop_row array .

I am using this right now but it is not giving me the required result.

str_replace("first_","",$cop_row);

I am getting output

pulse1second_pulse2

What I want is

pulse1pulse2

Thanks for your concern.

Answer 1

this will solve your problem.

php > $x = ['first_pulse', 'second_pulse'];
php > $q = preg_replace('/(\w+)_/i', '', $x);
php > print_r($q);
Array
(
    [0] => pulse
    [1] => pulse
)
php >
