How to Replace Array Strings in PHP

By Technology Last updated Wednesday, July/10/2024

1). Open your PHP file in a text editor, such as Windows Notepad.
2). Enter an array and assign it string values as below:

$my_array = array('str 1', 'str 2', 'str 3', 'str 4', 'str 2');
3). Create two variables as below, assigning them the search and replace string values for your array:

$search_value = "str 2"; $replace_value = "str 7";
4). Sort through the array with a "foreach" loop as below, using the "strcmp" function to check each array value for a match with the search string and replace it with the replacement string:

foreach($my_array as $k => $value) { if (strcmp($value,$search_value)==0) { $my_array[$k] = $replace_value; } }

This will replace the two instances of "str 2" with "str 7" and modify the array.
5). Save the PHP file.
