Case insensitive regular expression match

eregi

(PHP 4, PHP 5)

eregiCase insensitive regular expression match

설명

int eregi ( string $pattern , string $string [, array &$regs ] )

This function is identical to ereg() except that it ignores case distinction when matching alphabetic characters.

Warning

이 함수는 PHP 5.3.0부터 배제됩니다. 이 기능에 의존하지 않기를 권합니다.

인수

pattern

Case insensitive regular expression.

string

The input string.

regs

If matches are found for parenthesized substrings of pattern and the function is called with the third argument regs, the matches will be stored in the elements of the array regs.

$regs[1] will contain the substring which starts at the first left parenthesis; $regs[2] will contain the substring starting at the second, and so on. $regs[0] will contain a copy of the complete string matched.

반환값

Returns the length of the matched string if a match for pattern was found in string, or FALSE if no matches were found or an error occurred.

If the optional parameter regs was not passed or the length of the matched string is 0, this function returns 1.

예제

Example #1 eregi() example

<?php
$string 
'XYZ';
if (
eregi('z'$string)) {
    echo 
"'$string' contains a 'z' or 'Z'!";
}
?>

주의

Note:

PHP 5.3.0부터 regex 확장은 배제되었습니다. PCRE 확장이 같은 기능을 합니다. 이 함수를 호출하면 E_DEPRECATED 주의가 발생합니다. PCRE로 변환하는 데 필요한 도움은 차이점 목록을 참고하십시오.

Tip

eregi() is deprecated as of PHP 5.3.0. preg_match() with the i (PCRE_CASELESS) modifier is the suggested alternative.
