wordpress wp_get_archives output change with preg_replace

Question

good morning boys and girls...can someone point me to the right direction, please.

i want to replace my php-echo-output »JUNE 29, 2009–JULY 5, 2009« with just plain text: »last week«

<?php
ob_start();
wp_get_archives('type=weekly&limit=1');
$wklyarchives = ob_get_contents();
ob_end_clean();
$wklyarchives = preg_replace('%\&\#8211\;[a-zA-Z0-9, ]*\</a\>%s', 'last week</a>', $wklyarchives);
echo $wklyarchives;
?>

this preg_replace replaces just the 2nd part, so my output is now »JUNE 29, 2009last week« this preg makes me crazy...

Answer 1

You are only matching the dash and the part after it, so that's exactly what is getting replaced. If you add the same character class before the dash, like

[a-zA-Z0-9, ]%\&\#8211\;[a-zA-Z0-9, ]

it should work (depending on what $wklyarchives contains even before the 'JUNE 29' part; you might have to make sure you don't mach too much).

Answer 2

Okay, tried this with WordPress, worked fine:

'/[a-z0-9,]+ [0-9,]+ [0-9]+.?[a-z0-9,]+ [0-9,]+ [0-9]+/iu'

Remember, do not use output buffering with wp_get_archives. Use echo=0:

$wklyarchives = wp_get_archives("type=weekly&limit=1&echo=0");

Good luck.
