Using

With SearchReplace, you can replace a text in as many as desired files by another.

Example 25-1. Typical usage

<?php include 'File/SearchReplace.php' ; $files = array( "test1.txt",                 "test2.txt",                 "test3.txt" ) ; $ignoreline = array( "#", ":") ; $snr = File_SearchReplace( "Yes", "No", $files, "/mail/", false,                             $ignoreline) ; $snr -> doSearch() ; ?>

The example replaces all occurences of "Yes" with "No" in the given $files in the directory "/mail/". If a line in a file starts with one of the chars in $ignoreline, possible matches will be ignored.

You can do a new search without creating a new instance of the class.

Example 25-2. Do a new search

... // string to search $snr -> setFind( "Er") ; // string to find $snr -> setReplace( "Sie") ; // look in this files $snr -> setFiles( $files) ; // look in this directories $snr -> setDirectories( array( "/neue_briefe/")) ; // look in the subdirectories too $snr -> setIncludeSubdir( true) ; // ignore lines in the files starting with this chars $snr -> setIgnoreLines( array( "::", "#")) ; // restart search'n'replace $snr -> doSearch() ;

Types of search functions

File_SearchReplace supports different kinds of search functions. The type directly influence the format of the required $find-parameter

normal - default, the only type supporting the $IgnoreLines-parameter

quick - use str_replace()

preg - use preg_replace()

ereg - use ereg_replace()

To set the type, call setSearchFunction() before doSearch().
