I have a text file in the form of Name@Phone\n. I put the data into an array with explode(). How can I remove duplicate lines (values) based on Phone only? I want to avoid
Eddie@999-999-999
Ed@999-999-999
I want to make this unique based on the Phone.
<?php
$result = array();
foreach($dataset as $input):
$parts = explode('@', $input);
$result[$parts[1]] = $parts[0];
endforeach;
$result = array_flip($result);
$directories[$directory] = substr($directory,0,10); so that the date would end up being the key and the largest numbered time is the last to be created.If you don't care about the names and just want a list of unique numbers you can replace all characters in the listings that aren't numbers or dashes then do an array_unique():
$arr = array(
'Eddie@999-999-999',
'Ed@999-999-999'
);
$arr = preg_replace('/[^\d\-]/', '', $arr);
$arr = array_unique($arr);
print_r($arr);
If you know the numbers are always in that format (name@number) then the response from @Kenaniah works well.
Use:
$result = array();
foreach($arrayData as $data){
$uniqueKey = strstr($data, '@');//@999-999-999
$result[$uniqueKey] = $data;
}
var_dump( $result );
