[SOLVED] preg_split()

[php.ajax.coder]

I have a string like below

 

"hello it's 19:10"

 

I need to split by white space

 

leave : if its next to two numbers e.g. times otherwise remove

same for / for dates

 

Is there an easy way of doing this

 

Thanks

Do you mean explode to make a array, then work with the data.

 

not tested.

<?php

$word="hello it's 19:10";

$a=explode(' ',$word);

echo"<pre>";
print_r($a);
echo"</pre>";

?>

result tested.

<pre>Array
(
    [0] => hello
    [1] => it's
    [2] => 19:10
)
</pre>

This works for this string but i need to remove ":" from things like

 

"Hello: welcome"

[redarrow]

<?php

$word="hello: it's redarrow:";

$a=str_replace(':','',$word);

$b=explode(' ',$a);

echo"<pre>";
print_r($b);
echo"</pre>";

?>

 

result.

 

<pre>Array
(
    [0] => hello
    [1] => it's
    [2] => redarrow
)
</pre>

yes but that doesnt satisfy his other condition

 

leave : if its next to two numbers e.g. times otherwise remove

same for / for dates

geek way lol.

 

<?php

$word="hello: it's redarrow:";

$r=str_replace(':','',$word);

$a=explode(' ',$r);

$b=array_chunk($a,1);

echo"<pre>";
print_r($b); 
echo"</pre>";
?>

what wrong with this mate it works.

<?php

$word="hello it's redarrow";

if(strstr($word,':')){

$r=str_replace(':','',$word);

$a=explode(' ',$r);

print_r($a); 

}else{

$a=explode(' ',$word);

print_r($a);

}
?>

try this

<?php
$word="Hello: welcome / it's 19:10 12/03/2009";
$word = preg_replace('%(?<=[^\d])(:|/)(?=[^\d])%sm', '', $word);
$NewWord = preg_split('/\s+/sm', $word);
print_r($NewWord);
?>

 

EDIT: oops forgot about the date!

its a positive lookbehind that matchs any character that is NOT a A single digit.
