code as follows:
<?php
$array = array(
'abcd',
'abcde',
'bcde',
'cdef',
'defg',
'defgh'
);
$str = '~'.implode('~',$array).'~';
$word = $_GET['word']; //url = xxx.php?word=a
preg_match_all("/~({$word}(?:[^~]*))/i",$str,$matches);
var_dump($matches[1]);
//输出
//array(2) { [0]=> string(4) "abcd" [1]=> string(5) "abcde" }
//End_phpThe above is the detailed content of PHP sample code for filtering the first character of an array. For more information, please follow other related articles on the PHP Chinese website!
