带数组的strstr（）和stristr（）

Posted 2021-02-27

Searches an array $haystack for $needle. Returns the value of the element which contains the first result. Use strstr_array() for case-sensitive searches and stristr_array() for case-insensitive searches.

<?php
 
function strstr_array( $haystack, $needle ) {
	if ( !is_array( $haystack ) ) {
		return false;
	}
	foreach ( $haystack as $element ) {
		if ( strstr( $element, $needle ) ) {
			return $element;
		}
	}
}
 
function stristr_array( $haystack, $needle ) {
	if ( !is_array( $haystack ) ) {
		return false;
	}
	foreach ( $haystack as $element ) {
		if ( stristr( $element, $needle ) ) {
			return $element;
		}
	}
}
 
?>
