PHP str_replace function arguments are used as arrays

Str_replace for string substitution

The code is as follows	Copy Code
<?php Str_replace ("PHP", "java", "PHP Tutorial 4"); Java Tutorial 4 ?>

The variable being searched is a string

The code is as follows	Copy Code
<?php /* The variable being searched is a string */ $array =array (); $array []= ' PHP tutorial 1]; $array []= ' PHP tutorial 2]; $array []= ' PHP tutorial 3]; $array []= ' PHP tutorial 4]; $arrayNew =str_replace ("PHP", "Java", $array); Print_r ($ARRAYNEW); /* Array ( [0] => Java Tutorial 1 [1] => Java Tutorial 2 [2] => Java Tutorial 3 [3] => Java Tutorial 4 ) */ ?>

You can also handle variables in the form of an array, and the value you look for and the value you replace can be a pair of relationships

The code is as follows

Copy Code

<?php /* The variable to look for is an array form */ $array =array (); $array []= ' PHP tutorial 1]; $array []= ' PHP tutorial 2]; $array []= ' PHP tutorial 3]; $array []= ' PHP tutorial 4]; $find =array ("php", "tutorial"); $replace =array ("Java", "case"); $arrayNew =str_replace ($find, $replace, $array); Print_r ($ARRAYNEW); /* Array ( [0] => Java Case 1 [1] => Java case 2 [2] => Java case 3 [3] => Java case 4 ) */ ?>

The lookup value and the replacement value can be a many-to-many relationship

code is as follows

copy code

<?php /* The variable to look for is an array form */ $array =array (); $array []= ' PHP tutorial 1]; $array []= ' PHP tutorial 2]; $array []= ' PHP tutorial 3]; $array []= ' PHP tutorial 4]; $find =array ("php", "tutorial"); $arrayNew =str_replace ($find, "Java", $array);   Print_r ($ARRAYNEW);   /* Array (     [0] => javajava1     [1] =& Gt JAVAJAVA2     [2] => javajava3     [3] => javajava4 ) */
