EREGI(3) 1 EREGI(3)
eregi - Case insensitive regular expression match
SYNOPSIS
int eregi (string $pattern, string $string, [array &$regs])
DESCRIPTION
This function is identical to ereg(3) except that it 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
- Case insensitive regular expression.
o $string
- The input string.
o $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.
RETURN VALUES
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.
EXAMPLES
Example #1
eregi(3) example
<?php
$string = 'XYZ';
if (eregi('z', $string)) {
echo "'$string' contains a 'z' or 'Z'!";
}
?>
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(3) is deprecated as of PHP 5.3.0. preg_match(3) with the i ( PCRE_CASELESS) modifier is the suggested alternative.

ereg(3), ereg_replace(3), eregi_replace(3), preg_match(3), stripos(3), stristr(3), quotemeta(3).
