mixed substr_replace ( mixed $string , mixed $replacement , mixed $start [, mixed $length ] )

Replace text within a portion of a string

substr_replace() replaces a copy of string delimited by the start and (optionally) length parameters with the string given in replacement.


<?php
$var 
'ABCDEFGH:/MNRPQR/';
echo 
"Original: $var<hr />\n";

/* These two examples replace all of $var with 'bob'. */
echo substr_replace($var'bob'0) . "<br />\n";
echo 
substr_replace($var'bob'0strlen($var)) . "<br />\n";

/* Insert 'bob' right at the beginning of $var. */
echo substr_replace($var'bob'00) . "<br />\n";

/* These next two replace 'MNRPQR' in $var with 'bob'. */
echo substr_replace($var'bob'10, -1) . "<br />\n";
echo 
substr_replace($var'bob', -7, -1) . "<br />\n";

/* Delete 'MNRPQR' from $var. */
echo substr_replace($var''10, -1) . "<br />\n";
?>
