I have this php string
$mystring ="Yes YEs I am answering! On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >"
I want to split the string starting from "On Fri, Mar 21, 2014".How do I achieve this?
Note - the spilt condition can be general. i.e it can also be 'On Sat, Mar 22' or 'On Wed, Mar 29' etc
Also mention which php function should I use?
Because it would not work very good if you just split at the "On" word (could also exist in the text before, which I assume may be different), I suggest the following possibility:
$str = "Yes YEs I am answering! On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >";
if (preg_match('/^(.*)(On (Mon|Tue|Wed|Thu|Fri|Sat|Sun).*)$/', $str, $matches)) {
print_r($matches);
}
This gives you an output like the following, which should include all necessary values. Feel free to add an "i" after the second slash in the preg_match regex for case insensitive.
Array
(
[0] => Yes YEs I am answering! On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >
[1] => Yes YEs I am answering!
[2] => On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >
[3] => Fri
)
I would suggest a regex in order to do this, dieBeiden basically has it, though I would modify his regex a bit:
^(.*)(On (Mon|Tue|Wed|Thu|Fri|Sat|Sun), \w{3} \d{2}.*)$
$arr = explode('Yes YEs I am answering! ', $string);
It will find that word, delete it, and split on that place array!
And then you get
On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >"
next explode on ','
$arr = explde(',',$arr);
$strings = $arr[0].','.$arr[1];
Check this,this example I did found
<?php
$whois = "Record last updated on 10-Apr-2011.Record expires on 08-Oct-2012.Record Expires on 08-Oct-2008.";
$expires = preg_split('/Expires|expires/', $whois);
array_shift($expires);
echo "<pre>";
print_r($expires);
?>
gives
Array
(
[0] => on 08-Oct-2012.Record
[1] => on 08-Oct-2008.
)
You can also this
http://board.phpbuilder.com/showthread.php?10384775-RESOLVED-Split-String-at-first-word-match
you can use exploade function
Try with explode() like
$tempArr1 = explode('!' , $mystring);
$tempArr2 = explode(',' , $tempArr1);
echo $tempArr2[0].', '.$tempArr[1].', '.$tempArr[2];
If the initial part the string is ALWAYS "Yes YEs I am answering! " you can delete the first 24 characters from the string with the function
$mystring2 = substr($mystring, 24);
Also take a look at the explode() function ;)
You could us the explode function for this (https://www.php.net/explode) and split it on the word 'On', but when 'On' also occurs in the string, you're in trouble.
A better idea would be to use a regular expression with preg_split (http://www.php.net/manual/en/function.preg-split.php), with something like this:
<?php
$mystring ="Yes YEs I am answering! On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >";
$splitted = preg_split('/On ..., ... [0-9]{2}, [0-9]{4} at [0-9]:[0-9]{2} (AM|PM)/', $mystring);
var_dump($splitted);
?>
Feel free to make the regular expression more sophisticated :)
If you want to retain the datetime substring, then you can consume the leading space, then lookahead for as much of the datetime substring as you like.
Code: (Demo)
$mystring ="Yes YEs I am answering! On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >";
var_export(
preg_split('/ (?=On (?:Mon|Tue|Wed|Thu|Fri|Sat|Sun))/', $mystring)
);
Output:
array (
0 => 'Yes YEs I am answering!',
1 => 'On Fri, Mar 21, 2014 at 2:49 PM, Ajey Charantimath wrote: > answer to this question > > -- >',
)
