PHP case sensitive String Replace |
To replace a part of the string with another string we will use str_replace function in PHP. This function will replace all the occurrence of the string we target and will replace with the string we supply. Here is an example.
<?
$string="This is an example on how html is used in
developing user-friendly web sites. By using HTML we can
control the content of a page";
echo $string;
echo "<br><br>";
$string=str_replace("html","PHP",$string);
echo "<b>After replace</b> <br><br>$string";
?>
This is an example on how html is used in developing user-friendly web sites. By
using HTML we can control the content of a page
After replace
This is an example on how PHP is used in developing user-friendly web sites. By
using HTML we can control the content of a page
So you can see the text html is replace by PHP but HTML is not replaced.
So str_replace() is a case sensitive string replacing function. We can use str_ireplace() to get case insensitive string replacement
