My original string:

var_string= '[{"ImageNumber":"1","ImageLink":"[https://files.abc.com/flow1.png"}](https://files.abc.com/flow1.png), {"ImageNumber":"2","ImageLink":"[https://files.xyz.com/flow2.png"}](https://files.xyz.com/flow2.png)]'

This result that i want :

var_result= '[{"ImageNumber":"1","ImageLink":"(https://files.abc.com/flow1.png), {"ImageNumber":"2","ImageLink":"https://files.xyz.com/flow2.png)'

i have tried with:

preg_replace('/[(.*?)](.*?)/g', '',$var_string)

but result = null

Please help
