Using

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

Example 30-1. Typical usage

<?php
include 'File/SearchReplace.php' ;
$files = array( "test1.txt",
                "test2.txt",
                "test3.txt" ) ;
$ignoreline = array( "#", ":") ;
$snr = new 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 30-2. 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().
