if string contains

[dreamwest]

If i have 2 strings:

 

1234

 

and

 

HD1234

 

How can i tell php to only use "HD1234"

http://php.net/strpos

 

 

maybe?

<?php
$strings = array("the quick brown fox 1234", "the quick brown fox HD1234");

for($i = 0; $i < count($strings); $i++)
{
    if(strpos($strings[$i], "HD1234"))
    {
        echo $strings[$i];
    }
}

?>

@Prismatic:  I can't really think of any valid reason to ever use a for loop like this in PHP for arrays.

for($i = 0; $i < count($strings); $i++)
{

 

foreach would do it better:

foreach($strings as $key=>$string) {

be more specific.  Are you meaning to say that sometimes the string might be 1234 and sometimes it might be HD1234 and you only want to do something if it's HD1234?

Yes. Only if it has "HD" in the string.

 

Is there a contains function like this??

 

if str_contains("HD"){

Then do it

}else{ Dont do it
}

If that is the only thing in your string (not some number in a larger string), then you can do this:

 

$string = 'HD1234';
if (preg_match('~^HD[0-9]+$~',$string)) {
   // matches, do something
}
