php string replace
When it comes to replacing multiple values at a time, take two associative arrays.
One is for find words, another replacement.
1. str_replace(find-word, replace-word, $str, $variable[optional]); // case sensitive 2. str_ireplace(find-word, replace-word, $str, $variable[optional]); // case insensitive # Replace the existing string. # $variables are to find how many values have been replaced.
The Above can use this function with an array to replace any value.
$arr1 = str_replace('find', 'replacement', $arr);
$str = 'hello world!, the world is beautiful'; $arr_find = ['hello', 'world']; $arr_replace = ['hi', 'earth']; str_replace($arr_find, $arr_replace,$str); return $str = 'hi earth, this earth is beautiful';
- Replace the string from start to length.
substr_replace($str, replacement, start, length[optional])
- replace multiple words with an associative array. Where key is found, and replacement is value.
$strtr($str, 'find','replacement'); #replace multiple character
