I am trying to find the word and add a number next to it. How could he do? I tried with the code below, but I could not. Could anyone help me? Thank you!
$string = 'I220ABCD I220ABCDEF I220ABCDEFG'
if (preg_match("/I220.*/", $string, $matches)) {
echo $matches[0];
}
Expected result: I220ABCD9 I220ABCDEF10 I220ABCDEFG11
Use preg_replace_callback instead like this:
$str = 'I220AB FRRRR CD I221ABCDEF I220AB DSFDSF CDEFG';
$repl= preg_replace_callback('~(I220[^\s]+)~', function($m) {
static $i=9;
return $m[1] . $i++;
}, $str);
echo $repl\n"; // I220AB9 FRRRR CD I221ABCDEF I220AB10 DSFDSF CDEFG
I am trying to find the word and add a number next to it. And in your desired output I don't see any number being added.I dont know what your requirnments for adding the number at the end are so i just incremeneted during the loop;
$string = 'I220ABCD I220ABCDEF I220ABCDEFG';
$arrayStrings = explode(" ", $string);
$int = 9;
$newString = '';
foreach($arrayStrings as $stringItem)
{
if (preg_match("/I220.*/", $stringItem, $matches))
{
$stringItem = $stringItem.$int;
$newString = $newString.$stringItem." ";
$int++;
}
}
echo $newString;
$string = 'I220ABCD I220ABCDEF I220ABCDEFG';
// This requires PHP5.3+ since it's using an anonymous function
$result = preg_replace_callback('/I220[^\s]*/', function($match){
return($match[0].rand(0,10000)); // Add a random number between 0-10000
}, $string);
echo $result; // I220ABCD3863 I220ABCDEF5640 I220ABCDEFG989
You'll need to use a catch block in your regex e.g. "/I220([^ ]+)/" and if you want them all, you'll need to use preg_match_all, too.
foreach($matches as $match) { print_r($match); }preg_replace_callback with your needs:
$string = 'I220ABCD I220ABCDEF I220ABCDEFG';
class MyClass{
private static $i = 9;
private static function callback($matches){
return $matches[0] . self::$i++;
}
public static function replaceString($string){
return preg_replace_callback('/I220[^\s]+/',"self::callback",$string);
}
}
echo(MyClass::replaceString($string));
of course you can edit to class to initialize the way you want
