Q1:
See the script below
Q2 : n/a
Q3 : n/a
Q4 :
You have to find the insertion point with strpos, and then insert like this
$pos = strpos($mystring,$findme);
if ($pos>0)
{
$leftmost = substr($mystring,0,$pos);
$rightmost = substr($mystring,$pos,strlen($mystring)-$pos);
$new_string = $leftmost . "XPTO" . $rightmost;
}
else
$new_string = $mystring;
The script
<?php
$mystring = 'foo foo foo test Foo FOO Foo fOO foo';
$x = 'test';
$pos = strpos($mystring,$x);
echo "POS=$pos<br>";
$b = eregi_replace("foo","bar",$mystring);
echo "A=$mystring<br>B=$b<br>";
$leftmost = substr($mystring,0,$pos);
$rightmost = substr($mystring,$pos,strlen($mystring)-$pos);
$new_string = $leftmost . "XPTO" . $rightmost;
echo "NEW = $new_string";
?>
would result in
POS=12
A=foo foo foo test Foo FOO Foo fOO foo
B=bar bar bar test bar bar bar bar bar
NEW = foo foo foo XPTOtest Foo FOO Foo fOO foo
Does this help ?
