general question. regarding php functions

[piyush23424]

Hi,

do we have any php inbuilt function which returns true or false after checking a particular character (need to check comma) in a given string.

actually i want to conditionally explode a string i.e if string is having comma it will explode it by comma otherwise by space.

 

Thanks

how about:

 

if (preg_match(","$string))
{
    $string_array = explode(",",$string);
}

 

That should do the trick.

look at the 2 functions strpos() and strstr()

 

 

http://www.php.net/manual/en/function.strpos.php

http://php.net/manual/en/function.strstr.php

[piyush23424]

if (preg_match(",",$searchString))

    {

      $string_array = explode(",", $searchString);

    }

  else

    {

      $string_array = explode(" ", $searchString);

}

  echo "<pre>";

  print_r($string_array);

 

Output is warning error :

Severity: Warning

Message: preg_match() [function.preg-match]: No ending delimiter ',' found

Filename: controllers/cma.php

Line Number: 104

 

but its doing explode with space

Array

(

    [0] => 779,TAMIAMI

    [1] => TRL

    [2] => #6

)

preg_match() is a bit overkill for just looking for a character in a string

 

if(strpos($string,','))  is less overhead

if (preg_match(",",$searchString))

    {

      $string_array = explode(",", $searchString);

    }

  else

    {

      $string_array = explode(" ", $searchString);

}

  echo "<pre>";

  print_r($string_array);

I never tested the code, the following code works for me:

 

$string = "one,2,three,4";
if (preg_match("/,/",$string))
{
    $string_array = explode(",",$string);
}
echo "<pre>";
print_r($string_array);
