我尝试在sql数据库中查找字符串。如果我有字符串"a b c d e"，为了获得准确性结果，我尝试"选择...从。。。其中列 = 'a b c d e' 或列='a b c d' 或 column='a b c' 或..." ，我试图找到像这样获取内爆数组的方法：
[0]=>a b c d e,
[1]=>a b c d,
[2]=>a b c,
...
[n]=>a
Can i do
诸如此类？
谢谢。
您可以使用 preg_split() 标记字符串，构建数组，然后用 array_reverse() 反转它：
$string = 'foo bar baz';
$results = array(); $current = '';
foreach (preg_split('/ +/', $string) as $token) {
$current = strlen($current) ? "$current $token" : $token;
$results[] = $current;
}
print_r(array_reverse($results));
输出：
Array
(
[0] => foo bar baz
[1] => foo bar
[2] => foo
)
我不确定你为什么要这样做，但这样做会做到：
$string = "Hello everybody, nice to meet you";
$parts = explode(" ", $string);
$new_array = Array();
for($i = 0; $i < count($parts); $i++)
{
$new_array[$i] = '';
for($j = 0; $j < count($parts) - $i; $j++)
{
$new_array[$i] = $new_array[$i]." ".$parts[$j];
}
}
print_r($new_array);
这是输出：
Array
(
[0] => Hello everybody, nice to meet you
[1] => Hello everybody, nice to meet
[2] => Hello everybody, nice to
[3] => Hello everybody, nice
[4] => Hello everybody,
[5] => Hello
)
<?php
$string = "Hello everybody, nice to meet you";
//remove the comma
$string = str_replace(',', '', $string);
//explode for each words with ' '(space) delimiter
$path = explode(' ', $string);
$final = array();
array_push($final, implode(' ', $path));
foreach($path as $el){
//remove max array element
$last_el = count($path) - 1;
unset($path[$last_el]);
//set the final array one by one.
array_push($final, implode(' ', $path));
}
//Show the result.
foreach($final as $row){
echo $row . ' <br />';
}
?>
