$pattern
, string $string
[, array &$regs
] )This function is identical to ereg() except that it ignores case distinction when matching alphabetic characters.
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
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.
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.
Example #1 eregi() example
<?php
$string = 'XYZ';
if (eregi('z', $string)) {
echo "'$string' contains a 'z' or 'Z'!";
}
?>
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_DEPRECATEDnotice. See the list of differences for help on converting to PCRE.
eregi() is deprecated as of PHP 5.3.0. preg_match()
with the i (PCRE_CASELESS) modifier is the suggested alternative.
