[SOLVED] Changing 8 2009 to just 8

[HoTDaWg]

hi there

 

i get a feeling this is a really stupid question and i apologize for not trying harder to figure it out, i just cant get my head around it and my deadline is slowly winding down.

 

im trying to replace a string such as "8 2009" (or "12 2009") to just "8" here is what i have been experimenting with, but i cant seem to get it right:

<?php
$thatmonth = "8 2009";
preg_replace('/^[\d]+[\s\d]+$/','/^[\d]+$/',$thatmonth)
?>

 

any help would be greatly appreciated, thanks

preg_replace('~([0-9]+) 2009~', '$1', $Content);

If that is your entire string you can simply use string indexes.

 

$thatmonth = "8 2009";
echo $thatmonth[0];

$thatmonth = "8 2009";
echo $thatmonth[0];

 

That would work on single digit months... but in the event of double digits, you would have to know that there are two digits and echo out the first two indexes... based on the same assumptions (that the string only consists the format of month[space]year), sscanf comes to mind on this one for me:

 

$thatmonth = "12 2009";
sscanf($thatmonth, '%d', $month);
echo $month; // 12

What are string indexes? I've worked with them in Python, but I didn't know they existed in PHP

Well, a string is a series of charactes of which are stored in indexes..

 

Example:

$str = 'cat';
echo $str[0] . "<br />\n"; // output: c
echo $str[1] . "<br />\n"; // output: a
echo $str[2] . "<br />\n"; // output: t

Can you do $str[0,2] like in Python?

[nrg_alpha]

I'm not versed in python, so I don't know what $str[0,2] does.. is that like a range from index 0 to 2 or something?

With regards to php, I don't think you can specify something like that.

Nope. You would need to use substr.
