LEARN ABOUT PHP
eregi_replace
EREGI_REPLACE(3) 1 EREGI_REPLACE(3)
eregi_replace - Replace regular expression case insensitive
SYNOPSIS
string eregi_replace (string $pattern, string $replacement, string $string)
DESCRIPTION
This function is identical to ereg_replace(3) except that this ignores case distinction when matching alphabetic characters.
Warning
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
PARAMETERS
o $pattern
- A POSIX extended regular expression.
o $replacement
- If $pattern contains parenthesized substrings, $replacement may contain substrings of the form digit, which will be replaced
by the text matching the digit'th parenthesized substring; will produce the entire contents of string. Up to nine substrings
may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis.
o $string
- The input string.
RETURN VALUES
The modified string is returned. If no matches are found in $string, then it will be returned unchanged.
EXAMPLES
Example #1
Highlight search results
<?php
$pattern = '(>[^<]*)('. quotemeta($_GET['search']) .')';
$replacement = '\1<span class="search">\2</span>';
$body = eregi_replace($pattern, $replacement, $body);
?>
NOTES
Note
As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED
notice. See the list of differences for help on converting to PCRE.
Tip
eregi_replace(3) is deprecated as of PHP 5.3.0. preg_replace(3) with the i ( PCRE_CASELESS) modifier is the suggested alternative.
SEE ALSO
ereg(3), eregi(3), ereg_replace(3), preg_replace(3), quotemeta(3).
