Search and replace some value with multiple random values

Question

I have a file with the following content.

Some text bla-bla #date# other text #date# some other #date#

I need to replace #date# with some random date which I generate by using the following code with new random value for each #date#.

date('Y-m-d', strtotime( '+'.mt_rand(0,45).' days'))

At the moment all dates are replaced with the same value. Tks.

Sure, you need it identify all dates in the text file, iterate over them and replace them one by one. — arkascha

You can use preg_replace_callback to generate a new random date each time it replaces:

$string = 'Some text bla-bla #date# other text #date# some other #date#';
echo preg_replace_callback('/#date#/', function () { return date('Y-m-d', strtotime( '+'.mt_rand(0,45).' days')); }, $string);

Output:

Some text bla-bla 2019-01-22 other text 2019-02-16 some other 2019-02-19
