eregi

Name

eregi — Performs a non-case-sensitive POSIX regular expression match against the specified string.

Synopsis

string eregi(pattern, subject[, matches]); string pattern: Regex pattern to match string subject: String to search using the pattern array matches (optional): Array in which to store the search results

Returns

FALSE if no match is found; otherwise, the length of the full match if the matches parameter is specified or 1 if it's not specified

Description

This function works like ereg() except that it ignores the case when matching alphabetic characters. See ereg() for a description of its parameters and usage.

Note

eregi() handles case properly for ISO-8859-1 8-bit alphabetic characters such as ƒ.

Example

Example 1123. Simple string match (non-case-sensitive version)

$look_for = "Quick";
$string = "The quick brown fox jumped over the lazy dog";
if (!eregi($look_for, $string)) {
   echo "Didn't find $look_for. Not there, even lowercase.\n";
}
else {
   echo "Found $look_for.\n";
}
