First, we define the regular expression: 复制 [RegEx]$regEx = ‘(\S+)$’; Next, we need to define what we want to do with the matched string. In this case, we re-implement the Convert-HexToString function. 复制 $delegateScriptBlock = { param ($match); -join ( $mat...
Description I have been missing a core function in PHP to validate a regular expression. I am therefore proposing something like preg_validate(). There are some workarounds mentioned in this StackOverflow thread. But from my understandin...
