With this peace of code i replace the first and the last occurence of a word in string.
$text = 'A United States aircraft fly in United States in the United States area.';
$find = 'United States';
$replace = ' U.S ';
$firsto = preg_replace("/$find/", "$replace", $text, 1); // stolen in stackoverflow
$lasto = preg_replace(strrev("/$find/"),strrev($replace),strrev($firsto),1); // stolen in stackoverflow
$final = strrev($lasto);
echo "<br><br> $final";
In this example there are 3 occurrences of the word United States
and the code below replace the first and the last occurrence.
And Output: A U.S aircraft fly in United States in the U.S area.
my problem is that if
the occurrence of word = 2
like this:
$text = 'A United States aircraft fly in United States';
Using a modified version of the code above i want to replace only the first occurrence if there are only 2 occurrences
and output something like this.
Output: A U.S aircraft fly in United States.
else if occurrence > 2
use the code below. thanks
