How can I get a single word before or after another word in a given text. For example :
Text = "This is Team One Name"
and what if there is no word but digites before the middle word for example
Text= "This is 100 one Name"
How can I get the 100
?
How Can I get the word before and after One
, being Team
and Name
? Any regex pattern matching?
将它们捕获到组中
(?:(?<firstWord>\w+)\s+|^)middleWord(?:\s+(?<secondWord>\w+)|$)
This should do it:
function get_pre_and_post($needle, $haystack, $separator = " ") {
$words = explode($separator, $haystack);
$key = array_search($needle, $words);
if ($key !== false) {
if ($key == 0) {
return $words[1];
}
else if ($key == (count($words) - 1)) {
return $words[$key - 1];
}
else {
return array($words[$key - 1], $words[$key + 1]);
}
}
else {
return false;
}
}
$sentence = "This is Team One Name";
$pre_and_post_array = get_pre_and_post("One", $sentence);
<?php
$Text = "This is Team One Name";
$Word = 'Team';
preg_match('#([^ ]+\s+)' . preg_quote($Word) . '(\s[^ ]+)#i', $Text, $Match);
print_r($Match);
