I use these functions all the time:
<?php
function regexpmetaspecialchars($ps_str, $ps_delimiter = '/') {
$ha_replsearch = array('\\', '^', '$', '.', '[',
']', '|', '(', ')', '?', '*',
'+', '{', '}', $ps_delimiter);
$ha_replreplace = array('\\\\', '\\^', '\\$', '\\.',
'\\[', '\\]', '\\|', '\\(', '\\)',
'\\?', '\\*', '\\+', '\\{', '\\}', '\\'
. $ps_delimiter);
return str_replace($ha_replsearch, $ha_replreplace, $ps_str);
}
function regexpmetabracketspecialchars($ps_str, $ps_delimiter = '/') {
$ha_replsearch = array('\\', '^', '-', ']',
$ps_delimiter);
$ha_replreplace = array('\\\\', '\\^', '\\-', '\\]',
'\\' . $ps_delimiter);
return str_replace($ha_replsearch, $ha_replreplace, $ps_str);
}
function regexpmetareplacespecialchars($ps_str) {
$ha_replsearch = array('\\', '$');
$ha_replreplace = array('\\\\', '\\$');
return str_replace($ha_replsearch, $ha_replreplace, $ps_str);
}
// Function aliases:
//
function regexpspecialchars($ps_str, $ps_delimiter = '/') {
return regexpmetaspecialchars($ps_str, $ps_delimiter = '/');
}
function regexpbracketspecialchars($ps_str, $ps_delimiter = '/') {
return regexpmetabracketspecialchars($ps_str, $ps_delimiter = '/');
}
function regexpreplacespecialchars($ps_str) {
return regexpmetareplacespecialchars($ps_str);
}
?>
