Question

i’m just wondering how I can replace multiple instances of – with just one using php,

for example say I have

test----test---3

what could I do to replace the multiple instances of – with just 1 so it would be

test-test-3

thanks 🙂

Answer 1

Remove every repeating character:

$string = 'test----test---3';
echo preg_replace('{(.)\1+}','$1',$string);

Remove specific repeating character:

$string = 'test----test---3';
echo eregi_replace("-{2,}", "-", $string);

Remove specific repeating character the ‘ugly’ way:

$string = 'test----test---3';
echo implode('-',array_filter(explode('-',$string)));

Result for all snippets:

test-test-3
