PHP Extension

<?php

include("chilkat.php");

$success = false;

$sb = new CkStringBuilder();
$success = $sb->Append('www.chilkatsoft.com');

// The GetBefore method returns the contents of the string up to but not including
// the marker string.  If the remove flag is true, then both the returned string AND
// the marker are removed.
$removeFlag = false;
$marker = '.';
$substr = $sb->getBefore($marker,$removeFlag);
print 'substr = ' . $substr . "\n";
print 'sb contains: ' . $sb->getAsString() . "\n";

// Output:
// substr = www
// sb contains: www.chilkatsoft.com

$removeFlag = true;
$substr = $sb->getBefore($marker,$removeFlag);
print 'substr = ' . $substr . "\n";
print 'sb contains: ' . $sb->getAsString() . "\n";

// Output:
// substr = www
// sb contains: chilkatsoft.com

// If the marker is not found, and the removeFlag is true,
// then the entire string is returned and the sb is cleared.
// For example:
$sb->Clear();
$sb->Append('111--222--333--444');
$marker = '--';
$removeFlag = true;
while (($sb->get_Length() > 0)) {
    $substr = $sb->getBefore($marker,$removeFlag);
    print 'substr = ' . $substr . ', sb contains: ' . $sb->getAsString() . "\n";
}

// Output is:
// substr = 111, sb contains: 222--333--444
// substr = 222, sb contains: 333--444
// substr = 333, sb contains: 444
// substr = 444, sb contains:
