PHP提取行

Question

I need to extract "C:\Documents and Settings" from the last line of this data:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft
ExcludeSubDirs   REG_DWORD 0x1
ExtensionList  REG_SZ 
FirstAction          REG_DWORD 0x11
ThreatName          REG_SZ         C:\Documents and Settings
Owner          REG_DWORD 0x3
ProtectionTechnolog  REG_DWORD 0x1
SecondAction  REG_DWORD 0x11
DirectoryName  REG_SZ         C:\Documents and Settings

How can I extract "C:\Documents and Settings" or whatever the value is multiple times using PHP?

Answer 1

Use regular expressions

$str = 'your string';
preg_match_all('!HKEY.+?DirectoryName\s+REG_SZ\s+([^
]+)!s', $str."
HKEY", $matches);
$dirs = @array_map('trim', $matches[1]); 

Your matches will be in the $dirs array.
