Is there an inbuilt PHP function to replace multiple values inside a string with an array that dictates exactly what is replaced with what?
For example:
$searchreplace_array = Array('blah' => 'bleh', 'blarh' => 'blerh');
$string = 'blah blarh bleh bleh blarh';
And the resulting would be: 'bleh blerh bleh bleh blerh'.
You are looking for str_replace().
$string = 'blah blarh bleh bleh blarh';
$result = str_replace(
array('blah', 'blarh'),
array('bleh', 'blerh'),
$string
);
// Additional tip:
And if you are stuck with an associative array like in your example, you can split it up like that:
$searchReplaceArray = array(
'blah' => 'bleh',
'blarh' => 'blerh'
);
$result = str_replace(
array_keys($searchReplaceArray),
array_values($searchReplaceArray),
$string
);
array_values() is not necessary -- str_replace() will ignore the keys of arrays passed in as arguments 1 and 2 (find array and replace array).$string = 'blah blarh bleh bleh blarh';
$trans = array("blah" => "blerh", "bleh" => "blerh");
$result = strtr($string,$trans);
You can check the manual for detailed explanation.
IN CASE some one is looking for replacing same strings with different values ( per occurence ).. Example, to replace all ## by numbers++ OR values from an array-
$split_at = '##';
$string = "AA ## BB ## CC ## DD";
$new_string = '';
// echo $string;
$replace_num = 1;
$replace_arr = ['first' , 'second' , 'third'];
$split_at_cnt = substr_count($string, $split_at);
for ($split=0; $split <= $split_at_cnt; $split++)
{
$new_string .= str_replace('##', ($replace_num++)." : ".$replace_arr[$split], substr( $string, 0, strpos($string, $split_at)+strlen($split_at)));
$string = substr($string, strpos($string, $split_at)+strlen($split_at));
}
echo $new_string;
