Wildcard?

[ERuiz]

I have a script which receives _POST data from a program. I need to make sure that any data that has 747 in it, will be given a value I determine.

 

I was thinking about something along these lines:

 

 

$aircraft = $_POST[aircraft];

 

if ($aircraft == "%747%") {

 

$aircraft = "B747";

 

}

 

Would that work? I was thinking along the lines of the mySql LIKE commands where a % would be a wildcard. In other words, I want to check the variable $aircraft and if this variable has any reference to "747" (ej. Boeing747 or B747-200, et etc), then it will simply make it "B747".

 

Thanks for any help...

You actually use a function for this:

 

$aircraft = $_POST[aircraft];
$similar = strpos($aircraft, '747');

if($similar || $aircraft == "747") {
$aircraft = "B747";
}

 

In strpos, the first argument is the variable to search in and the second is what to search for. It returns a true if it could find it, a false if it couldn't.

Wrong function!

 

<?php
$aircraft = '400';
$similar = strpbrk($aircraft, '747');

if($similar) {
$aircraft = "B747";
}
echo  $aircraft;               // B747
?>

 

Anything with a "7" or a "4" in it will return true .

regex functions tend to be a lot slower. Use only when necessary.
