PHP Array values in string?
I have been looking around for a while in the PHP manual and can't find any command that does what I want.
I have an array with Keys and Values, example:
$Fields = array("Color"=>"Bl","Taste"=>"Good","Height"=>"Tall");
Then I have a string, for example:
$Headline = "My black coffee is cold";
Now I want to find out if any of the array ($Fields) values match somewhere in the string ($Headline).
Example:
Array_function_xxx($Headline,$Fields);
Would give the result true because "bl" is in the string $Headline (as a part of "Black").
I'm asking because I need performance... If this isn't possible, I will just make my own function instead...
EDIT - I'm looking for something like stristr(string $haystack , array $needle);
Thanks
SOLUTION - I came up with his function.
function array_in_str($fString, $fArray) {
$rMatch = array();
foreach($fArray as $Value) {
$Pos = stripos($fString,$Value);
if($Pos !== false)
// Add whatever information you need
$rMatch[] = array( "Start"=>$Pos,
"End"=>$Pos+strlen($Value)-1,
"Value"=>$Value
);
}
return $rMatch;
}
The returning array now have information on where each matched word b开发者_如何学Goegins and ends.
This should help:
function Array_function_xxx($headline, $fields) {
$field_values = array_values($fields);
foreach ($field_values as $field_value) {
if (strpos($headline, $field_value) !== false) {
return true; // field value found in a string
}
}
return false; // nothing found during the loop
}
Replace name of the function with what you need.
EDIT:
Ok, alternative solution (probably giving better performance, allowing for case-insensitive search, but requiring proper values within $fields parameter) is:
function Array_function_xxx($headline, $fields) {
$regexp = '/(' . implode('|',array_values($fields)) . ')/i';
return (bool) preg_match($regexp, $headline);
}
http://www.php.net/manual/en/function.array-search.php that's what you looking for
example from php.net
<?php
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');
$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array); // $key = 1;
?>
